Answer:

85

Step-by-step explanation:

68 x 5 = 340

80 x 3 = 240

340+240=580

750-580= 170

170 ÷ 2 ====== 85

What percent of 160 is 56?
kakasveta [241]
160 = 100%
56 = x%

then you would cross multiply

160x = 56(100)

160x = 5600

x = \frac{5600}{160}

x = 35

so

35% of 160 is 56.

How did i work this out?
bogdanovich [222]

knowing the answer is between 3 & 4 plug those as x and see what you get for answers than adjust the number accordingly

3^3+2(3) = 33 so its higher than 3

4^3 + 2(4) = 72 so it is lower than 4

try the middle so try 3.5

3.5^3 + 2(3.5) = 49.875

question states use 1 decimal place so now try 3.6

3.6^3+2(3.6) = 53.856


3.5 is closest
