I think 6 because 12=3x-6
Answer:
x=1
Step-by-step explanation:
5-2x=3
-2x=3-5
-2x=-2
x=1
98+(3x-17)=180
81+3x=180
180-81=3x
3x=99
x=33
Write and solve an equation of ratios:
900 students 45 teachers
------------------ = -----------------
x 110 teachers
Cross multiplying, we get (900)(110) / 45, or
so x = # of students in the high school = 2200 (answer)
Answer:
Ayden meet his goal, because I paint 83% of the house that is greater than 80%
Step-by-step explanation:
to know the part that he painted with respect to the total we have to divide the amount that he paint by the total amount
415ft² / 500ft² = 0.83
if we want it as a percentage we simply multiply it by 100
0.83 * 100 = 83%
now we compare the percentage that I paint with what was his goal
83% > 80%
