1. one number added to three times another number is 24. five times the first number added to
three times the other number is 36. find the numbers.

Step-by-step explanation:

x + 3y = 24multiply by -1

5x + 3y = 36

-x - 3y = -24 (result of multiplying by -1)

5x + 3y = 36

add

4x = 12

x = 12/4

x = 3 <

x + 3y = 24

3 + 3y = 24

3y = 24 - 3

3y = 21

y = 21/3

y = 7 <

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
