6-2x=2(15-x)
distribute
6-2x=30-2x
add 2x to both sides
6=30

For the following linear equations, determine which inverse operation allows you to determine the solution of the equation. In y

VARVARA [1.3K]

Answer:

see explanation

Step-by-step explanation:

(1)

Given

$\frac{n}{5}$ = - 0.3

Since n is divided by 5 then use the inverse operation, multiplication.

Multiply both sides by 5 to clear the fraction

n = 5 × - 0.3 = - 1.5

(2)

Given

- 2n = 4 $\frac{1}{3}$ ← change to an improper fraction

- 2n = $\frac{13}{3}$

Since n is multiplied by - 2 then use the inverse operation, division.

Divide both sides by - 2

n = $\frac{13}{-6}$ = - $\frac{13}{6}$

1.C

2. 130, answer not listed

3. A

4. B

5.C

Step-by-step explanation:

To solve equations with fractions, convert from a mixed number to an improper fraction then use the inverse. The inverse of a fraction is multiplying by the reciprocal of the fraction on both sides.

$2\frac{1}{4}r=10\\\\\frac{9}{4}r=10\\\\\frac{4}{9} *\frac{9}{4}r=10*\frac{4}{9}\\\\r=\frac{40}{9} \\\\r=4\frac{4}{9}$

$\frac{h}{26}=5\\\\\frac{26}{1} *\frac{h}{26}=5*\frac{26}{1}\\\\h=130$

$\frac{6}{7}k=6\\\\\frac{7}{6} *\frac{6}{7}k=6*\frac{7}{6}\\\\k=\frac{42}{6} \\\\k=7$

$\frac{4}{5}x\\\\\frac{4}{5}*\frac{5}{8}\\\\\frac{20}{40} \\\\\frac{1}{2}$

$\frac{h}{4/9} \\\\\frac{\frac{16}{3} }{\frac{4}{9} } \\\\\\\frac{\frac{16}{3} *\frac{9}{4}}{\frac{4}{9}*\frac{9}{4}}\\\\\frac{16}{3} *\frac{9}{4}\\\\\\\frac{144}{12} \\\\12$
