Help solve for r algebra

Mathematics
1 answer:
bija089 [108]4 years ago
6 0

Answer:

\frac{20}{7}

Step-by-step explanation:

Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

7r=4(5)

Simplify: 7r=20

Divide both sides of the equation by 7 to get: r=\frac{20}{7}

YO PLZ HELP!! MARKING BRAINIEST!!
Yuliya22 [10]

Answer:

x = 26, 16

Step-by-step explanation:

( x-21) ^2 = 25

Take the square root of each side

sqrt(( x-21) ^2) = ±sqrt(25)

x-21 = ±5

Add 21 to each side

x-21+21 = 21±5

x = 21±5

x = 21+5  and x = 21-5

x = 26, 16
