Answer:
r = 2.75
Step-by-step explanation:
1.25 + r = 4
Subtract 1.25 on both sides.
1.25 + r - 1.25 = 4 - 1.25
r = 4 - 1.25
r = 2.75
The solution to the equation is r = 2.75.
The answer is c
Have a good day !!!!!
This has infinitely many solutions if that is all that the question asked...
2x+3y=12
3y=-2x+12
y=(-2x+12)/3
So for any value of x you choose it will give you the corresponding y value that makes your original equation true.
Answer:
A:40%
B:7.8
Step-by-step explanation:
Using a proportion , you can solve for the bottom side.
13/19.5 = 5.2/x
multiply 19.5 and 5.2 and rewrite the equation
101.4=13x
x=7.8
To find the scale, divide 5.2 by 13
5.2/13=0.4
Double check by dividing 7.8 by 19.5
7.8/19.5=0.4
0.4=40%
