Answer:
D. 20/7
Step-by-step explanation:
Since
4/7 = x/5
Multiply the left side by x and the right side by 4 as shown below
7*x = 4*5

Then dividing both sides by 7 would cancel on the left
7x/7=x
X = 20/7

Answer:
X=6,-4
Step-by-step explanation:
0=x^2-2x-24
First substitute x with 6
0=(6)^2-2(6)-24
36-12-24
=0
Now try -4
0=(-4)^2-2(-4)-24
Two negative numbers time each other turns it into a positive number -4 x -4=16
24-24=0
