Question

4t +3.82=27.42
5t - 2.54 = 7.66
7.2m-3.2m-8.12=0.38
3.2n-0.2n-9.36=0.54
решите и распишите , спасибо

Answer 1

Пошаговое объяснение:

4t +3.82=27.42

4t=27,42–3,82

4t=23,6

t=5,9

5t - 2.54 = 7.66

5t=7,66+2,54

5t=10,2

t=2,04

7.2m-3.2m-8.12=0.38

7.2m-3.2m=0,38+8,12

4m=8,5

m=2,125

3.2n-0.2n-9.36=0.54

3,2n–0,2n=0,54+9,36

3n=10

n= $frac{10}{3}$

n= $3 frac{1}{3}$

Answer 2

Ответ:

1.t=5.9

2.t=2.04

3.m=2.125

4.n=3.3

Пошаговое объяснение:

1 пример

$4t + 3.82 = 27.42$

$4t = 27.42 -3.82$

$4t = 23.6$

$t = 5.9$

2 пример

$5t - 2.54 = 7.66$

$5t = 7.66 + 2.54$

$5t = 10.2$

$t = 2.04$

3 пример

$7.2m - 3.2m - 8.12 = 0.38$

$4m - 8.12 = 0.38$

$4m = 0.38 + 8.12$

$4m = 8.05$

$m = 2.125$

4 пример

$2n - 0.2n - 9.36 = 0.54$

$3n - 9.36 = 0.54$

$3n = 0.54 + 9.36$

$3n = 9.9$

$n = 3.3$
