Answer:
C.
2.67 inches by 2.27 inches
Step-by-step explanation:
We can use ratios to solve
1 in x inches
-------- = ---------
7.5 ft 20 ft
Using cross products
1*20 = 7.5x
Divide each side by 7.5
20/7.5 =7.5x/7.5
2.67 =x
We can do the same for the other dimension
1 in x inches
-------- = ---------
7.5 ft 17 ft
Using cross products
1*17 = 7.5x
Divide each side by 7.5
17/7.5 =7.5x/7.5
2.27 =x
2.67 inches by 2.27 inches
Answer:
B (2.5, 0)
Step-by-step explanation:
2x - y = 5 (multiply all by 4)
8x- 4y = 20
-8x - 4y = - 20
eliminate the 4y
8x- 4y = 20
-8x - 4y = - 20
-------------------- –
16x = 40
x = 40/16 = 2.5
now we substitute x with 2.5
2x - y = 5
2(2.5) - y = 5
y = 0
