What number 3 times equals 49

16.3333 (and so on)

Step-by-step explanation:

This is easy to figure out by using the inverse operation of multiplication, which is division. We divide 49/3, which equals 16.3 (with the 3 repeating), so that is the answer!

Hope this helps and have a nice day (～*▽*)～

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

$12. that is my answer.
