Let x = the boys
3x = the girls
x + 3x = 180
4x = 180
4x/4 = 180/4
x = 45 boy's profit.
3x = 3(45) = 135 girl's profit.
We could use the proportion
7/12=?/60
Then do 60×7=420
Then 420/12= 35
It takes Kiara 35 minutes to get ready for school
The answer is 16 because you have to solve for T which is 4 So you will multiply 4 times 4 because T is for 4 and you had to put parentheses around 4...4×4 is eight and you have to subtract 24-8 and it will give you 16
The value of x is 9.
Solution:
Proportionality theorem:
<em>If a line is parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>
In the given triangle, the middle line is parallel to the base, so the sides are in the same ratio.
Do cross multiplication.
⇒ 9 × 56 = 72(3x – 20)
⇒ 504 = 216 x – 1440
Add 1440 on both sides of the equation.
⇒ 1944 = 216 x
Divide by 216 on both sides of the equation.
⇒ 9 = x
Switch the sides.
⇒ x = 9
The value of x is 9.
