n+3 the sum of a number and three means a number plus three.
7n+10
10
10 + 15a * * * * * No! It is 10 + n/15
n/6+10=n/2 n/6+10=3n/6 10=2n/6 60=2n 15=n
2(n + 10)

n = 5.
They have n in common.
12 more than a number means: __+12 (a number plus 12). You can express this as an algebraic expression: n+12 or 12+n(n representing a number.)
Six times a number minus five is less than twice the number plus ten. 6 * n - 5 < 2 * n + 10 6n - 5 < 2n + 10 4n - 5 < 10 4n < 15 n < 15/4 This statement will hold true for all n < 15/4
n+3 the sum of a number and three means a number plus three.
7n+10
10
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
