3 boys + 8 girls = 11 students
3 boys/ 11 students = x boys /33 students
using cross products
3 * 33 = x*11
divide by 11
99/11 = x
x=9
There are 9 boys
Answer:
x= 14
Step-by-step explanation:
When the triangles are similar, they should have a similar ratio that makes one side equal to another. In this case, the ratio is 1.5 as 24 divided by 16 is 1.5. Now, taking the side that is "similar" to the x-value which is 21, we divided 21 by 1.5 resulting in x= 14.
Answer:
21x - 15
Step-by-step explanation:
if this answer helped u and u liked it, pls mark as brainliest! thx!
Step-by-step explanation:
a= 16x+3-14x+15
combine like terms, 16x-14x= 2x
so,
2x+3+15,
15+3=18
18=2x, divide 18 by 2
x=9
b) *open the parenthesis* -1/6 *24x = -4x
-1/6*60 = -10
-4x- (-10)= -4x+10
-4x+10+2x= -4x+2x= -2x
-2x=10 = 2x=-10 = x=-5
Cheers!
2 1/2, 3, 3 1/2, 4, 4 1/2, 5
I hope this helped!!:)
