Answer:
A. -(5y+2) + y = 5
Step-by-step explanation:
Solving the above Equation given to us in the Question,
-x + y = 5...... Equation 1
x - 5y = 2....... Equation 2
Step 1
We make x subject of the formula in Equation 2
---> x= 5y + 2
Step 2
This would be to substitute 5y + 2 for x in Equation 1
-x + y = 5...... Equation 1
-(5y+2) + y = 5
Hence, Option A is the correct option
11x + 18 = 172 not a test i need the right awnser
Answer:
x=14
Step-by-step explanation:
11x+18=172, subtract 17 from both sides, 11x=154, divide 11 from both sides, x=14
Which of the following numbers is between 5 and 10 on a number line? Select two that apply.
Answer:
√38 , √44
Step-by-step explanation:
√25 = 5 and √100 = 10
So, required numbers should be between √25 and √100
And so, they are √38 , √44

Johnny and Dustin both went bowling last weekend, but not together. Johnny went during open bowling time, paying $13 for shoe rental and $3 per hour. Dustin went on family night, when each hour was $4 and shoe rental was $3. As it turned out, they played for the same number of hours and spent the same amount. How much did each one spend? How many hours did each one bowl?
Answer:
10 hours
$43
Step-by-step explanation:
Given that:
Jonny:
Shoe rental = $13
Fee per hour = $3
Dustin :
Shoe rental = $3
Fee per hour = $4
Number of hours bowled is the same
Let number of hours bowled = x
$13 + 3x = $3 + 4x
3x - 4x = $3 - $13
-x = - 10
x = 10
Number of hours each bowled = 10
Amount spent :
Jonny:
$13 + 3x = $13 + $3(10) = $13 + $30 = $43
Dustin :
$3 + 4x = $3 + $4(10) = $3 + $40 = $43

A concert charges $5 for a children's ticket and $11 for an adult’s ticket. One Saturday, the theater sold 1200 tickets for $10,800. How many children’ tickets and adults’ tickets were sold?
Answer:
i think 15 kid and 18 aduits
Step-by-step explanation:
Answer:
800 children’s ticket were sold and 400 adult tickets were sold
Step-by-step explanation: using elimination
variables-
amount of children’s ticket sold: C
amount of adult tickets sold: A
equations-
A+C=1200
5A+11C=10,800
solving-
(A+C=1200) -5 —> -5A-5C=-6000
5A+11C= 10,800
use elimination on those two equation and you get C=800, A=400.
to check you plug in the numbers into one of the equations, doesn’t matter which one.
The Micro Devices Company earned 3,632,859,678 dollars this year. 2,459,632,852 dollars were earned last year. Which is the best estimate of how many more dollars were earned this year than last year?
Answer:
$1,173,226,826
Step-by-step explanation:
The estimate of the increase in dollars earnings is the difference between this year's earnings and last year's earnings. In other words, the increase in earnings is the excess of current year's earnings over last year's earnings as computed below:
increase in earnings=this year's earnings-last year's earnings
this year's earnings=$3,632,859,678
last year's earnings=$2,459,632,852
increase in earnings=$3,632,859,678-$2,459,632,852
increase in earnings=$ 1,173,226,826

Answer:
A 33 degrees
Step-by-step explanation:
[tex]x \degree = 180 \degree - (23 \degree + 124 \degree) \\ \\ x \degree = 180 \degree - 147 \degree\\ \\ x \degree = 33 \degree \\ \\ x = 33[/tex]
Answer:
A) 33
Step-by-step explanation:
the angles of a triangle always add up to 180.
124 + 23 + x = 180
combine like terms
147 + x = 180
147 + x - 147 = 180 - 147
x = 180 - 147
x = 33

ABCD is a rhombus.
Find each angle.
Reason:
Plz answer ASAP, thank you
Answer:
Step-by-step explanation:
I sympathize. The question is not very clear: you don't know what A and B really are (I mean which vertex).
However it is a rhombus, and you are to assume that B follows A. So put A anywhere and make B follow it. They are supplementary which means they add to 180 degrees. All rhombi have that property.
A + B = 180
A/B = 2/1
Cross Multiply the second equation
A = 2*B
Put 2B into the first equation.
2B + B = 180 Combine the left terms
3B = 180 Divide both sides of the equation by 3
B = 180 / 3
B = 60
B = 60
A = 180 - 60 = 120
Label the two acute angles as 60 and the two obtuse angles as 120.
Acute: means less than 90
Obtuse: means more than 90

In an isosceles trapezoid, how do you prove the base angles are congruent?
Answer: Well there's a geometry definition stating that the two angles are equal.
But ig i can try to make a proof.
First make a perpendicular bisector from the vertex to the bottom splitting the bottom side in half.
Now because of LL theorem, and the reflexive property, the two triangles are equal.
Now using cpctc, the two angles are also equal.

Identify an equation in point-slope form for the line parallel to y+-2/3x+8 that passes through (4, -5).
Step-by-step explanation:
Line parallel to the line y = -2/3 x + 8 also has the slope -2/3.
Since the line passes through (4, -5), we have (x - 4) written on the right side and (y + 5) on the left side.
Hence the equation is y + 5 = -2/3 * (x - 4). (B)

Describe and correct the error in finding the intercepts.
Example:
The intercept is not at (8, 2) because... Instead, it
should be...
Answer:
The x=8 is only for the x interecept, and the x-intercept is (8,0). You assume y to be 0 then you say it's 2, that is incorrect. x and y interecepts should not be combined. The correct x-intercept and y-intercept are (8,0) and (0,2) respectively
