If n + 7 = 10, evaluate 2n - 2<br> O 3<br> 0 17<br> 4<br> 6
Alexandra [31]

Answer:

The value of 2n - 2 is 4.

Step-by-step explanation:

Given the equation

n + 7 = 10

Subtract  7 from both sides of the equation

n+7-7=10-7

Simplify

n=3

Now substituting n = 3 in the equation

2n - 2 = 2(3) - 2

          = 6 - 2

          = 4

Therefore, the value of 2n - 2 is 4.

What is the step by step to solved a divide decimal 1.52 divide by 1.9
lora16 [44]

ANSWER

0.8

EXPLANATION

We want to simplify

1.52 \div 1.9

We convert the decimals to fractions

\frac{152}{100}   \div  \frac{19}{10}

We multiply by the reciprocal of the second fraction.

\frac{152}{100}   \times \frac{10}{19}

\frac{19 \times 8}{100}   \times \frac{10}{19}

Cancel the common factors to obtain,

\frac{8}{10}  =  0.8
