Answer 1

Respuesta:

Explicación paso a paso:

5m - 3 = 37

5m = 37 + 3

5m = 40

m = 40/5

m = 8

9c = 27   c = 27/9   c = 3

√a = 9

(√a)² = 9²

a = 9 x9    a = 81

6 + √y = 8

√y = 8 - 6

(√y)² = 2²

y = 4

2x/5 = 8

2x = 5 * 8

2x = 40

x =40/2

x = 20

y² - 23 = 58

y² = 58 + 23

y² =  81

√y² = √81

y = 9

8m + 78 = 86

8m = 86 - 78

8m =  8

m = 8/8    m = 1
