Find the value of x. Round to the nearest tenth.

10.

Step-by-step explanation:

According to Pythagoras,

14^2 = 10^2 + x^2

196 = 100 + x^2

x^2 = 196-100

x^2 = 96

x = 9.8

x = 10  (nearest tenth)

Hope,  this will help and please mark me as brainliest.

Let x be the number of apples 
Let y be the number of oranges 

x+y≤20 
0.24x+0.8y≤12

x≤20-y 

0.24(20-y)+0.8y≤12
4.8-0.24y+0.8y≤12
0.56y≤7.2
y=12.9 (you can choose 12 here, since you can't have a fraction of an orange sold) 

x= 7.14 (again, rounding this off to 7) 

Therefore, Darcy got 12 oranges and 7 apples. 

Hope I helped :)
