Simplify 10(n + 3).

10n + 30
10n + 13
10n + 3

N+3 evaluates to N+3
Multiply 10 by N+3

Multiply 10 by each term in N+3 term by term.

This is the distributive property of multiplication.

Multiply 10 and N
Multiply 1 and N

The N just gets copied along.
10 × N = 10N

Multiply 10 and 3
10 × 3 = 30

10*(N+3) evaluates to 10N+30

***The final answer is 10N+30***

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
