Answer:
Step-by-step explanation:
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126
Answer:
The two angles are 54 degrees and 126 degrees.
Answer:
63
Step-by-step explanation:
15 x 4.2
15 x 42 (get rid of the decimal by moving it one to the right)
15 x 42 = 630
630 = 63.0 (put the decimal back in by placing it one spot to the left)
Answer: 63
hope this helps :)
Simple Interest , I = PRT/100
Where P = Principal, R = Rate, T = Time in years
Time, T = (100*I)/(P*R)
T = 100* 84 / (600 * 7) Use your calculator
T = 2
Time is 2 years.
1306.66
If we divide 3920 by three, we get 1306.66.
