How would you begin to answer this question- solve for x if, 2x + 3x = 10. what’s the answer? Plz help me! I’m desperate
Answer:
You would begin to start this equation by combining like terms.
Step-by-step explanation:
To start you would first combine 2x + 3x and you get 5x. From there you would solve 5x=10. Now you would divide by 5 on both sides to get x=2.
7. A BOOKSTORE WAS SELLING BOOKS FOR 50% OFF. A SHELF IN THE STORE HAD A SIGN AS SHOWN:
"BOOKS ON THIS SHELF TAKE AN ADDITIONAL 25% OFF"
LETA PICKED OUT BOOKS FROM THE DISCOUNT SHELF THAT HAD A REGULAR PRICE OF $100. HOW MUCH
DID LETA PAY FOR THE DISCOUNTED BOOKS?
Answer:
Leta payed $37.50
Step-by-step explanation:
50% is another way of saying half. So half of 100 is 50. She is down to $50.00 If you take another 25% off then it is $37.50. This is because 25% of 50 is 12.50. If you subtract 12.5 from 50 then you get 37.50. This is how I know it is $37.50. Hope this helps! :)
find the total pay for the week $12.50 per hour time and a half for sunday hours worked day must be rounded to the nearest quarter hour.
Answer:
$392.19
Step-by-step explanation:
I find it less tedious to write equations in a spreadsheet than to do the arithmetic by hand.
Morning time and afternoon time are found by subtracting the start time from the end time. Then the time for the day is found by adding the morning and afternoon shift hours.
Rounding to the nearest quarter hour can be done a couple of ways. In a spreadsheet, you multiply hours by 4, round to an integer, then divide that integer by 4 to get the rounded hours. (In a spreadsheet, hours are 1/24 of a day. When the hours:minutes are converted to decimal, you get a number of days. To make hours again, you need to multiply that by 24.)
Of course, hours are multiplied by $12.50 to get pay for all days but Sunday. For Sunday, that product is again multiplied by 1.5 for "time and a half."
The total pay is $392.19.

Q
Lin
Elena
Q
Noah
Answer:
For Lin's answer
Step-by-step explanation:
When you have a triangle, you can flip it along a side and join that side with the original triangle, so in this case the triangle has been flipped along the longest side and that longest side is now common in both triangles. Now since these are the same triangle the area remains the same.
Now the two triangles form a quadrilateral, which we can prove is a parallelogram by finding out that the opposite sides of the parallelogram are equal since the two triangles are the same(congruent), and they are also parallel as the alternate interior angles of quadrilateral are the same. So the quadrilaral is a paralllelogram, therefore the area of a parallelogram is bh which id 7 * 4 = 7*2=28 sq units.
Since we already established that the triangles in the parallelogram are the same, therefore their areas are also the same, and that the area of the parallelogram is 28 sq units, we can say that A(Q)+A(Q)=28 sq units, therefore 2A(Q)=28 sq units, therefore A(Q)=14 sq units, where A(Q), is the area of triangle Q.
The reason is while computing the area is found to be 14 square units.
What is area of triangle?The area of Triangle = 1/2* base * height
given:
assumed area to be 14 square units
We will take the case of Elena
In figure the base = 7 units
height = 4 units
Area of triangle
=1/2*base*height
=1/2 * 7 * 4
=7*2
=14 square units

An online test of English spelling looked at how well people spelled difficult words. The bar graph to the right shows how many people per 100 spelled each word correctly. a. Estimate the number of people per 100 who spelled weird correctly. Round to the nearest 5. b. In a group consisting of 8724 randomly selected people, estimate how many more people can correctly spell weird than inoculate.
Answer:
a). 85 people
b). 4362 people
Step-by-step explanation:
The given bar graph shows how many people per 100 spelled each word correctly.
a. From the graph given extreme end of the bar for the word "weird" is between 80 - 90.
Therefore, approximate number of the persons who spelled weird correctly will be 85 (rounded to the nearest 5).
b. The number of people who can correctly spelled word "weird" = 85
The number of people who can correctly spelled word "inoculate" = 35
In 100 people, number of people who can correctly spell "weird" more than "inoculate"
= 85 - 35
= 50
in a group of 8724 randomly selected people, number of people who can spell the word "weird" correctly more than "inoculate"
= [tex]\frac{50}{100}\times 8724[/tex]
= 4362 people
Random selection means each individual has equal chance of being selected.
Given graph has the following information:
Total number of people under survey=100
a. To estimate the number of people per 100 who spelled weird correctly
From the graph it is around 84 and rounding it to nearest 5 will results in 85.
b. From the graph,
Number of people can correctly spell inoculate= 35
Number of people can correctly spell weird than inoculate=85-35
=50 out of 100
Using unitary method as follows:
100-------->50
1------------>1/2
8724------>1/2x8724
=4362
Thus, out of 8724 randomly selected people, 4362 people can correctly spell weird than inoculate.

A physical therapy facility is building a new pool that is 60 feet long and 7 feet deep. They have ordered enough tile for a
140-foot-long border around the edge. How wide should the pool be to ensure that all tiles are used?
Answer:
The Pool should be 10 feet wider
Step-by-step explanation:
The rectangngle shaped pool will have 4 sides...
If the Pool is 60 feet long then 120 feet should be covered by Tiles.
so only Tiles of 20 feet are left...
Hence the border will be 10 on one side and 10 on the other side
The Pool should be 10 feet wider
The calculation is as follows:
The rectangle-shaped pool will have 4 sides
In the case when the Pool is 60 feet long then 120 feet should be covered by Tiles.
Thus, only Tiles of 20 feet are left...
Therefore,
Hence the border will be 10 on one side and 10 on the other side

Note: Undefined is a terminology used to refer to a mathematical expression that has not been assigned a value or isn't correct. Also, a mathematical expression is considered to be undefined when its denominator is zero (0) i.e it is divided by zero (0).
Substituting the given values into the slope formula, we have;
Undefined [tex]= \frac{2 - [-1]}{-3 - a}[/tex]
Undefined [tex]= \frac{2 + 1}{-3 - a}[/tex]
Next, we would equate the denominator to zero (0);
[tex]-3 - a = 0[/tex]
a = -3

The endpoints of RS are R(−4,3) and S(16,18). Complete each statement using a fraction.
a. (8,12) is the point ___ of the way from R to S.
b. (0,6) is the point ___ of the way from R to S.
Answer:
a) (8,12) is the point [tex]\frac{3}{5}[/tex] of the way from R to S, b) (0, 6) is the point [tex]\frac{1}{5}[/tex] of the way from R to S.
Step-by-step explanation:
Let be [tex]X[/tex] a point in the line between endpoints [tex]R[/tex] and [tex]S[/tex]. The ratio of the line segment [tex]RX[/tex] to the line segment [tex]RS[/tex] is given by:
[tex]r = \frac{RX}{RS}[/tex]
Where:
[tex]RX = \sqrt{(x_{X}-x_{R})^{2}+(y_{X}-y_{R})^{2}}[/tex]
[tex]RS = \sqrt{(x_{S}-x_{R})^{2}+(y_{S}-y_{R})^{2}}[/tex]
Let be [tex]x_{R} = -4[/tex], [tex]y_{R} = 3[/tex], [tex]x_{S} = 16[/tex] and [tex]y_{S} = 18[/tex].
a) If we know that [tex]x_{X} = 8[/tex] and [tex]y_{X} = 12[/tex], the ratio of the line segment [tex]RX[/tex] to the line segment [tex]RS[/tex] is:
[tex]RX =\sqrt{[8-(-4)]^{2}+(12-3)^{2}}[/tex]
[tex]RX = 15[/tex]
[tex]RS =\sqrt{[16-(-4)]^{2}+(18-3)^{2}}[/tex]
[tex]RS = 25[/tex]
Then,
[tex]r = \frac{15}{25}[/tex]
[tex]r = \frac{3}{5}[/tex]
(8,12) is the point [tex]\frac{3}{5}[/tex] of the way from R to S.
b) If we know that [tex]x_{X} = 0[/tex] and [tex]y_{X} = 6[/tex], the ratio of the line segment [tex]RX[/tex] to the line segment [tex]RS[/tex] is:
[tex]RX =\sqrt{[0-(-4)]^{2}+(6-3)^{2}}[/tex]
[tex]RX = 5[/tex]
[tex]RS =\sqrt{[16-(-4)]^{2}+(18-3)^{2}}[/tex]
[tex]RS = 25[/tex]
Then,
[tex]r = \frac{5}{25}[/tex]
[tex]r = \frac{1}{5}[/tex]
(0, 6) is the point [tex]\frac{1}{5}[/tex] of the way from R to S.
