Divide by 10 both sides and you get a=4
So we have 299790000, we want to have only one digit in front of the decimal, 2.9979x10^9
hope this helps :)
I don't think you use a fraction. You multiply .6666 by 72 which equals 47.9952 or rounded 48. :)
Answer:
<u>The smaller angle measures 44° and the larger measures 136°</u>
Step-by-step explanation:
Let'e recall that supplementary angles are two angles whose sum is 180° degrees.
Smaller angle = x
Larger angle = 3x + 4
Therefore, we have:
x + 3x + 4 = 180
4x = 180 - 4
4x = 176
x = 176/4
x = 44 ⇒ 3x + 4 = 136
<u>The smaller angle measures 44° and the larger measures 136°</u>
