Answer:
Find the value of x, if 8,x, x, 50 are in proportion.
If a,b,c and d are in proportion then we have a/b = c/d
Now we need to find the value of x given if 8, x, x, 50 are in proportion.
So we have 8/x = x/50
Or x x x = 8 x 50
Or x^2 = 400
Or x = ±√400
Or x = ± 20
Therefore the value of x will be + 20 or - 20

Answer:
Step-by-step explanation:
We need x first.
AB = DE
12 = 3x -3
4 = x -1 . . . . . divide by 3
5 = x
Now, we can find y.
∠C = ∠F
7x +y = 55
y = 55 -7x = 55 -7(5)
y = 20

Answer:
19
Step-by-step explanation:
I found it by making 4 3/4 to 4 6/8 by multiplying the numerator and denominator by 2, so the denominators can be equivalent, and then you do 4 6/8 ÷ 2/8 = 19
Answer:
3/4
Step-by-step explanation:
Choose two coordinates on the line and use the slope formula to figure out the slope.
For example, use coordinates (0,-1) and (4,2).
Slope formula: y2-y1/x2-x1
2--1/4-0 = 3/4
