Step-by-step explanation:
Let's solve your equation step-by-step.
0.75(8+e)=1.25e
Step 1: Simplify both sides of the equation.
0.75(8+e)=1.25e
(0.75)(8)+(0.75)(e)=1.25e(Distribute)
6+0.75e=1.25e
0.75e+6=1.25e
Step 2: Subtract 1.25e from both sides.
0.75e+6−1.25e=1.25e−1.25e
−0.5e+6=0
Step 3: Subtract 6 from both sides.
−0.5e+6−6=0−6
−0.5e=−6
Step 4: Divide both sides by -0.5.
−0.5e−0.5=−6−0.5
e=12

Answer:
x ≥ 88
Step-by-step explanation:
In order to have at least an average of 80 after 4 tests, the sum of her scores must be at least 80 * 4 = 320 so we can write the following inequality:
71 + 78 + 83 + x ≥ 320
232 + x ≥ 320
x ≥ 88
