Answer:
24.6
Step-by-step explanation:
Given that the length of RT is 43 and that RE is 4x+7 and that ET is 2(x-4), we can use PWP to set up an equation to find the value of x.
4x+7+2(3x-4) = 43
4x+7+6x-8 = 43
10x = 44
x = 4.4
Then, we plug in 4.4 into the equation.
4*4.4+7=24.6
Sorry for the delay, hope this helps!

3(x+4)= 3x+12
3x+12+x+3+x=5x + 15
5x+15=180
5x=180-15
5x=165
x=165/5
x= 33min
mowing the grass = 3(x+4)
= 3(33+4)
=99+12
