Answer:

Step-by-step explanation:

∠DEF = x

∠ABC = 2*x = 2x

∠DEF + ∠ABC = 90  {as they are complementary}

x +2x = 90

3x = 90

x = 90/3

x = 30

A printer is printing photos. For every 15 photos, the printer takes 3 minutes.
Alex17521 [72]

Answer:

3:15, 5:25, 7:35, 8:40, 10:50

Step-by-step explanation:

When I first tried this I thought it was for every one there was fifteen. I messed up then looked, realized, and changed it. For every 3 there is 15 so 15 ÷ 3 = 5 so when I saw the 5 I multiplied it by five to get 25 then continued throughout. Your first step when doing these problems again is to divide (but make sure you divide the right number) then once you find out that sweet number, multiply is by the time to get the photos, and divide by five on the photos to get the time.

<em>Hope you got this right!</em>
