<span>90/x=100/18</span>
<span>(90/x)*x=(100/18)*x - </span> multiply both sides of the equation by x
<span>90=5.55555555556*x - </span>divide both sides of the equation by (5.55555555556) to get x
<span>90/5.55555555556=x </span>
<span>16.2=x </span>
<span>x=16.2</span>
<span>18% of 90=16.2

Answer:
1.25
Step-by-step explanation:
Because they are equal triangles, all of their sides are equal
so, lets take one side of each triangle (4, 5)
the law:
the scale factor = the larger side ÷ the smaller side
x = 5 ÷ 4
x = 1.25
For checking:
the larger side = the smaller side × the scale factor
Y = 4 × 1.25
Y = 5
No 5/8 is not greater then 2/3, 5/8 is just 1/24 smaller then 2/3.
Answer:
Step-by-step explanation:
1) 17x + 175 = y
2) 17(28) + 175 = y
476 + 175 = y
651 = y
Cost for bus and 28 students is $651
3) 889 - 175 = 714
714/ 17 = 42
42 students attempted the trip
