A student is collecting dimes and quarters as a fundraiser for their CAS project. After the first week, they tasked a younger sibling to count them up, who found there to be 211 coins. After taking the coins to the bank, the student was given $37.30. Find how many dimes did the student collect, and how many quarters did the sudent collect?
Answer: [tex]103,108[/tex]
Step-by-step explanation:
Given
There are total of 211 coins
The worth of the coins is [tex]\$37.30[/tex]
Suppose there are x dimes and y quarters
A dime is equivalent to 10 cents and quarter is equivalent to 25 cents
[tex]\therefore x+y=211\quad \ldots(i)\\\Rightarrow 0.1x+0.25y=37.30\\\Rightarrow x+2.5y=373\quad \ldots(ii)[/tex]
Solving (i) and (ii) we get
[tex]x=103,y=108[/tex]
Therefore, student collects 103 dimes and 108 quarters.

If I think of a number halve it and subtract 2 results is 10.write equations and solve it please
Answer:
24
Step-by-step explanation:
let 'x' = number
x/2 - 2 = 10
add 2 to each side to get:
x/2 = 12
cross-multiply to get:
x = 24
Answer:
The equation is (x/2) - 2 = 10The equation solves to x = 24============================================================
Explanation:
x = the number you think of
x/2 = the result after taking half of that number
(x/2) - 2 = subtract 2 from the previous result
(x/2) - 2 = 10 is the equation to solve
Solving said equation gets us...
(x/2) - 2 = 10
x/2 = 10+2 ... adding 2 to both sides
x/2 = 12
x = 12*2 ..... multiplying both sides by 2
x = 24
Notice how we basically undo everything applied to x. First we divided by 2, then we subtracted 2. So we follow that order in reverse to undo the "minus 2" (ie add 2 to both sides). Then we undo the division to multiply both sides by 2 to end up with the answer x = 24
-----------------
Let's check that answer:
x = 24
x/2 = 24/2 = 12 ... result after taking half of x
(x/2) - 2 = (12)-2 = 10 ... result after subtracting two
We end up with 10 as your teacher mentioned, so it confirms that x = 24 is the answer.
------------------
Here's another way to check:
(x/2) - 2 = 10
(24/2) - 2 = 10
(12) - 2 = 10
10 = 10
We end up with the same thing on both sides, so x = 24 is confirmed.

quentin is going to buy a pair of pants that cost $32.50. he has a coupon for 20% off the price of one item and another coupon for $5.00 off the price of one item. he can only use one coupon. which coupon should quentin use to save the most money
Answer:
20% coupon
Step-by-step explanation:
20% of 32.50 = 6.5
32.50 - 6.50 = 26
32.50 - 5 = 27.50
26 is less than 27.50, therefore, the 20% off coupon should be used to save him $1.50.

Find the value of x.
Answer:
x = 16
Step-by-step explanation:
Angles in a triangle add up to equal 180
Hence, 9x - 8 + x + 10 + x + 2 = 180
^ ( note that we just created an equation that we can use
to solve for x )
We now solve for x using the equation created.
9x - 8 + x + 10 + x + 2 = 180
step 1 combine like terms
9x + x + x = 11x
-8 + 10 + 2 = 4
we now have 11x + 4 = 180
step 2 subtract 4 from each side
180 - 4 = 176
4 - 4 cancels out
we now have 11x = 176
step 3 divide each side by 11
176 / 11= 16
11x / 11 = x
we're left with x = 16

Solve for w
5w.+ 36°
Зw
Answer:
w=18
Step-by-step explanation:
So, lets go over what we know:
A line is 180 degrees.
5w+36 is the first part of the line.
3w is the other part of the line.
So 5w+36 and 3w is 180 degrees.
We can write this as:
5w+36+3w=180
Combine the 5w and 3w:
8w+36=180
Subtract 36 from both sides:
8w=144
Divide 8 from both sides to get w alone:
w=144/8
=
w=18
Hope this helps!

To write the equation of a line in slope-intercept form, there are two things we need: the y-intercept and the slope.
To find the y-intercept using a graph is relatively easy. We are looking to see where the line crosses the y-axis. In this case, that is at the point (0,4).
To find the slope, we need to first find two points that are on the line. I will be using the points (0,4) and (2,5), though you can use any two that you would like. Then, we'll need to use the slope formula (y2 - y1 / x2 - x1).
(5 - 4) / (2 - 0)
1 / 2 = slope
Now that we have the slope and y-intercept, we can simply plug those values into slope intercept form, y = mx + b, where m is the slope and b is the y-intercept.
Therefore, our equation of the line in fully simplified slope-intercept form is y = 1/2 x + 4.
Hope this helps!! :)
Answer:
y = 1/2x + 4
Step-by-step explanation:
Slope-intercept form is: y = mx + b
The slope is 1/2 (mx)
Up 1, Over 2, which is the space between each dot.
The y-intercept is 4 (b)
The point where the line crosses the y-axis.
y = 1/2x + 4
Hope this is correct for you!
Lian has $1.00. She has only nickels and dimes. Lian has twice as many dimes as nickels. How many dimes does she have?
Answer: 8
Step-by-step explanation:
Given
Lian has [tex]\$1.00[/tex] and she has twice as many dimes as nickels
Suppose she has [tex]x[/tex] nickels
So, the number of dimes is [tex]2x[/tex]
Nickel is equivalent to 5 cents and dime is equivalent to 10 cent
[tex]\therefore \ x(0.05)+2x(0.1)=1\\\Rightarrow 0.05x+0.2x=1\\\Rightarrow 0.25x=1\\\Rightarrow x=4[/tex]
Therefore she has 8 dimes with her.

What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
where -
{m} is the slope of the line.
{c} is the {y} - intercept.
Given is that the equation {y} = ax describes the graph of a line.
It is asked to find that if the value of {a} is negative, then what would be the orientation of the line.
The general equation of a straight line is -
y = mx + c
Here {m} denotes the unit rate. Unit rate is the rate at which the value of {y} changes per unit change in the value of {x}. So, we can write that the orientation of the line is going down and to the left.
Therefore, if the value of a is negative, the line is going down and to the left.

Thirty students were asked what their favorite number from 1 through 9 was. The results were 8 students said 3. 6 students said 4, 9 students said 7, and 2 students said 9. What is the experimental probability that the number 7 was picked as the favorite number?
Answer:
3/10
Step-by-step explanation:
From the question, we have the total number of sampled students as 30
9 students said 7 was their favorite
So the experimental probability that we have 7 picked as the favorite number will be the number of respondents who chose 7 as their favorite divided by the total number of respondents
We have this as;
9/30 = 3/10

Answer:
x = 14
m<D = 57
Step-by-step explanation:
All triangle interior angles add up to 180.
<D and <E are congruent because of the congruent legs which makes them congruent angles:
4x + 1 + 4x + 1 + 5x - 4 = 180
13x - 2 = 180
13x = 180 + 2
13x = 182

If m is a common divisor of x and y, then x/y = (x ÷ k)/______
Answer:
[tex]\frac{x}{y} = \left(\frac{x}{y} \right)\cdot 1 = \left(\frac{x}{y}\right)\cdot \left(\frac{m}{m} \right) = \frac{\frac{x}{m} }{\frac{y}{m} }[/tex]
Step-by-step explanation:
The common divisor is the greatest natural number so that two or more natural numbers have no remainder. If [tex]m[/tex] is a common divisor of [tex]x[/tex] and [tex]y[/tex], then [tex]p = \frac{x}{m}[/tex] and [tex]q = \frac{y}{m}[/tex], where [tex]p[/tex], [tex]q[/tex] [tex]\in \mathbb{Z}[/tex]. Then, we have the following expression:
[tex]\frac{x}{y} = \left(\frac{x}{y} \right)\cdot 1 = \left(\frac{x}{y}\right)\cdot \left(\frac{m}{m} \right) = \frac{\frac{x}{m} }{\frac{y}{m} }[/tex]
