The answer is 18.13
(145/8) ÷ 2 » 18.125 ÷ 2 = 9.0625 is how I get this answer
Answer:
x = 5, y = 4
Step-by-step explanation:
x + 4y = 21
4x - 16 = y
x + 4(4x - 16) = 21
x + (16x - 64) = 21
(17x - 64) = 21
17x = 85
x = 85/17
x = 5
___________________
x + 4y = 21
5 + 4y = 21
4y + 5 = 21
4y = 16
y = 16/4
y = 4

Answer:
24 inches
Step-by-step explanation:
The television is a rectangular screen, the diagonal represents the hypotenuse side while the length and height are the adjacent and opposite side in no particular order hence we can use Pythagoras theorem to find the length.
Recall that the theorem states that
opposite side^2 + adjacent side^2 = hypotenuse side^2
let the length of the television screen be L
L^2 + 18^2 = 30^2
L^2 + 324 = 900
L^2 = 900 - 324
L^2 = 576
L = √576
= 24 inches
Answer:
w = 11
Step-by-step explanation:
<u>Step 1: Subtract 4 from both sides</u>
15 = w + 4
15 - 4 = w + 4 - 4
11 = w
Answer: w = 11
The formula for the area of a parallelogram is
A=b*h where b=base and h=height
We know that the height is 1/2 foot. But for the base, we need to subtract 1/8 from 3/4
b=3/4-1/8=6/8-1/8=5/8
the base is 5/8 foot
now we can solve
A=5/8*1/2=5/16 or 0.3125 feet
Answer=5/16 or 0.3125 feet
