Question

Rearrange the equation so r is the independent variable. 10q-5r=30

Answer 1

Answer:

hey mate

Ans- r=2q-15

Step-by-step explanation:

10q-5r=30

-5r=-10q+30

r=2q-15

Answer 2

"The equation so n is the independent variable is r = 2q - 6

Step-by-step explanation:

"GIVEN

• Expression 10q - 5r = 30

"TO FIND

• Rearrange the equation so r is the independent variable.

"SOLUTION

Equation → 10q - 5r = 30

• Add 5r on both side

10q - 5r + 5r = 30 + 5r

10q = 30 + 5r

• Subtract 30 on both side

10q - 30 = 30 + 5r - 30

5r = 10q - 30

• Divide both side with 5

r = 2q - 6

"» Therefore, the equation so r is the independent variable is r = 2q - 6
