Answer:
$1350
Step-by-step explanation:
5% of 1000 is 50
50x7 is 350
1000+350=1350
Answer:
54
Step-by-step explanation:
The two angles add to 90 degrees since they are complementary
the ratio is 3:2
Multiply by x
3x:2x
Add them together and set equal to 90
3x+2x=90
5x=90
Divide each side by 5
5x/5 = 90/5
x = 18
The first angle is 3*18 = 54
The second angle is 2*18 = 36
Answer: 3.5
Step-by-step explanation:
Hello! To answer this question we have to make an equation. In this equation I will represent the total number of songs Lou has as the variable x.
So 4x +6x + x = 682
This simplifies to 11x = 682. When you divide both sides by 11 you get x = 62. This is how many songs Lou has.
Since we are trying to find how many songs Kelly has, we must multiple 62 x 4 to get 248. Kelly has 248 songs.
