Paraphin [41]3 years ago

Answer:

a=2

Step-by-step explanation:

Subtract 2a from both sides.

9a−2−2a=12

Combine 9a and −2a to get 7a.

7a−2=12

Add 2 to both sides.

7a=12+2

Add 12 and 2 to get 14.

7a=14

Divide both sides by 7.

a= $\frac{14}{7}$

Divide 14 by 7 to get 2.

a=2

aksik [14]

Step-by-step explanation:

Increase the number by 5% of its value.

Percentage increase = 5% × 220

New value =

220 + Percentage increase =

220 + 5% × 220 =

(1 + 5%) × 220 =

(100% + 5%) × 220 =

105% × 220 =

105 ÷ 100 × 220 =

105 × 220 ÷ 100 =
