Answer:
Number of people in each car = x = 8
Number of people in each van = y = 22
Step-by-step explanation:
Let
Number of people in each car = x
Number of people in each van = y
8x + 8y = 240 (1)
4x + y = 54 (2)
From (2)
4x + y = 54 (2)
y = 54 - 4x
Substitute y = 54 - 4x into (1)
8x + 8y = 240 (1)
8x + 8(54 - 4x) = 240
8x + 432 - 32x = 240
8x - 32x = 240 - 432
-24x = -192
x = -192/-24
x = 8
Substitute x = 8 into (2)
4x + y = 54 (2)
4(8) + y = 54
32 + y = 54
y = 54 - 32
y = 22
Number of people in each car = x = 8
Number of people in each van = y = 22
Solve for y .−5y−8(−7y+4)=−7−9(2−y)

Answer:
y = 7/50
Step-by-step explanation:
-5y + 56y - 32 = -7 - 18 + y
50y = -25 + 32
50y = 7
y = 7/50
Answer:
[tex] \frac{1}{2} [/tex]
Step-by-step explanation:
Open the bracket
[tex] - 5y + 56y - 32 = 7 - 18 + 9y[/tex]Collect the like terms
[tex]51y - 9y = - 11 + 32[/tex]
[tex]42y = 21[/tex]
Divide both sides by 42
[tex]y = \frac{21}{42} [/tex]
[tex]y = \frac{1}{2} [/tex]

Please help! A robotic vacuum cleaners can clean 2 square feet of carpet in 8 minutes. About how long does it take for it to clean a carpet covering a room with the dimensions shown below?
Answer: 6480
Step-by-step explanation: So since the dimensions are easy to calculate, just multiply 9 by 4 and 15 by 3, then you get 36 and 45. Multiply 36 by 45 and you get 1620, but since the vacuum can get 2 square ft, then divide by 2 and you get 810. Since it takes 8 minutes to clean up, multiply 810 by 8 and you get 6480. I do believe

A tessellation has 2 pairs of congruent angles around the point of intersection. The measure of each of one pair of congruent angles is 28∘. What is the measure of each one of the other pair of congruent angles? The measure of each one of the other pair of congruent angles is
9514 1404 393
Answer:
152°
Step-by-step explanation:
If two pairs of congruent angles total 360°, then the different angles must total 180°. The other angle measure is 180° -28° = 152°.
The measure of each angle in the other congruent pair is 152°.
Last week the waiter received $80 in tips. This week the waiter received $63 in tips. What is the percent decrease in tips from last week to this week?
A 0.21%
B 21%
C 22%

The area of a circle is 81 pi in2 what is the circumference in inches express ur answer in terms of pi
Answer:
Circumference of circle = 18π inches
Step-by-step explanation:
Given the following data;
Area of circle = 81π in²
To find the circumference;
First of all, we would find the radius of the circle using the area of circle formula.
Area of circle = πr²
Substituting into the formula, we have:
81π = πr²
Dividing both sides by π, we have;
81 = r²
Taking the square root of both sides, we have;
r = 9 inches
Now, to find the circumference of the circle;
Circumference of circle = 2πr
Circumference of circle = 2*π*9
Circumference of circle = 18π inches.
Find the area. The figure is not drawn to scale.
Answer:
A = 1/2 (13) ( 9 +9)

Hello There!
The shown angles have a sum of 90 degrees
This is noticeable because there is a square at the vertex which indicates that its a right angle
A right angle has a measure of 90 degrees
That being said we can create an equation to solve for x
90 = 66 + 8x having made an equation we now solve for x
step 1 subtract 66 from each side
90 - 66 = 24
66 - 66 cancels out
now we have
24 = 8x
step 2 divide each side by 8
8x/8=x
24/8=3
we're left with x = 3
Answer:
x=3
Step-by-step explanation:
8x+66=90 complement
8x=90-66
x=24/8=3

Step-by-step explanation:
#8 A boogie board that has a regular price of $70 is on sale at a 35% discount. Find the selling price.
Answer:
45.5
Step-by-step explanation:
To find 35% of 70, you have to use the equation...
70 x 35/100
70 x 35 = 2,450
2,450/100 = 24.5
24.5 is 35% of 70, so the item is now $24.5 less than the original price.
70 - 24.5 = 45.5
The selling price is $45.5
