In the picture find 15 and 20 the answer for 16) 3/2= 150%
All the corners of a rectangle is equal to 90 degrees. So you need to set (x-1) and (2x+10) equal to 90 and then solve for x.
(x - 1) + (2x + 10) = 90
<em>Combine the like terms...
</em>3x + 9 = 90
<em>Subtract both sides by 9...
</em>3x + 9 - 9 = 90 - 9
3x = 81
<em>Divide both sides by 3...
</em><em>3x = 81
</em>(3x) / 3 = 81 / 3
x = 27

Step-by-step explanation:
<u>Step 1: Make an expression</u>
150 - 7.50x = 112.50
<u>Step 2: Solve the expression for x</u>
150 - 7.50x = 112.50
150 - 7.50x - 150 = 112.50 - 150
-7.50x / -7.5 = -37.5 / -7.5
x = 5

Answer:
Step-by-step explanation:
Let the 4 greatest numbers be, A, B, C D
(A + B + C + D)/4 = 8
Total sum = 4 × 8
= 32
Let the 4 lowest numbers be, D, E F G,
(D + E + F + G)/4 = 20
Total number = 4 × 20
= 80
Hence, the difference between the sums of the 3 greatest number and the 3 smallest numbers:
A, B, C and E, F, G
= D + (E + F + G) - (A + B + C) - D
= (E + F + G) - (A + B + C)
= 80 - 32
= 48.
