Let the number of boys be x
Let the number of girls be x + 4
(x + 4) + x = 28
x + x + 4 = 28
2x + 4 =28
2x = 28 - 4 → 2x = 24 → x = 24 / 2 → x = 12
The number of boys is 12, so the girls are 12 + 4 = 16
Ratio of girls to boys → 16 : 12 → 4 : 3
Ratio of girls to boys is 4:3
Answer:
2)16.5
Step-by-step explanation:
step1:v/2.2 -0.1=7.4
add 0.1 on both sides
step2:v/2.2=7.5
multiply by 2.2 on both sides
step3:v=16.5
2) v/2.2 - 0.1 = 7.4
v/2.2 = 7.4 + 0.1
v /2.2 = 7.5
v = 7.5 * 2.2
v = 16.5
4) -1.3g + 1.9 = -11.1
-1.3g = -11.1-1.9
-1.3g = -13
g = -13/-13
g = 1
6) -14.3 = -1.4 -3d
-14.3 + 1.4 = -3d
-12.9 = -3d
3d = 12.9
d = 12.9/3
d= 4.3
and a height of 17.25 feet. Jamal's
neighbor's roof has an area of 942 square
feet. What is the difference in area
between Jamal's roof and his neighbor's?
Answer: 103.65 square feet
Step-by-step explanation:
To find Jamal’s roof area: 97.2 x 17.25 = 1,676.7. Divide by two because it’s a triangle (gets you to 838.35).
Subtract 838.35 from neighbors roof area (gives you 103.65)
