Question

0.7(3s+4)−1.1s=7.9 I need a answer

Answer 1

Answer:

$\boxed {s = 5.1}$

Step-by-step explanation:

Solve for the value of $s$:

$0.7(3s + 4) - 1.1s = 7.9$

-Use Distributive Property:

$0.7(3s + 4) - 1.1s = 7.9$

$2.1s + 2.8 - 1.1s = 7.9$

-Combine like terms:

$2.1s + 2.8 - 1.1s = 7.9$

$s + 2.8 = 7.9$

-Subtract $2.8$ to both sides:

$s + 2.8 - 2.8 = 7.9 - 2.8$

$\boxed {s = 5.1}$

So, the value of $x$ is $5.1$.

Answer 2

First, expand the bracket

2.1s + 2.8 - 1.1s = 7.9

Next, collect like terms

s + 2.8 = 7.9

Lastly subtract 2.8 from 7.9 to get your answer.

s = 5.1

(Hope this helps! ^^)
