75 protein bars must be sold to equal the income!
Answer:
x=-19
y=55
Step-by-step explanation:
y=-3x-2.
5x+2y=15
substitute y into 5x+2y =15
5x +2 (-3x-2) = 15
distribute
5x -6x-4 = 15
combine like terms
-x-4 =15
add 4 to each side
-x-4+4 = 15+4
-x=19
multiply by -1
x = -19
now lets find y
y= -3x-2
y = -3(-19) -2
y = 57-2
y =55
The answer is 140.
Hope this helped :D
The answer is 33 meters
use the Pythagorean theorem
56^2+x^2=65^2
3136+x^2=4225
x^2=1089
x=33
