7) Which number is a factor & of 15, but not a multiple
of 5?
A. 3
B. 10
C. 6
D. 9
factor

The correct answer is 3.

Step-by-step explanation:

Three is not a multiple of five because it is smaller than five, but it is a factor of 15 because 3 * 5 = 15

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
