Answer:
14) y = 81
15) n = 6
Step-by-step explanation:
14)
54:30 = y:45
cross multiply: 45(54) = 30y, so y = 81
15)
6:3 = 12:n
cross multiply: 12(3) =6n, so n = 6
<span>16=4²
25=5²
</span>So that means the square root of 22 is between 4 and 5.
Square 4.5
4.5² = 20.25
<span>4.5 < √22 < 5
So the nearest whole number would be 5.

If you have some scratch paper handy, you can divide the track into 2 semi circles, and one rectangle. Multiply the length (100) by two since a rectangle has 2 lengths (one on top, one on bottom). However, do not add the widths to the final perimeter because it is not part of the track. Now to find the semicircles (the two curves on each end). The circumference of a circle is 2

Answer:
x = 87/11 = 7.909
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
22x - 174 = 2 • (11x - 87)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : 11x-87 = 0
Add 87 to both sides of the equation :
11x = 87
Divide both sides of the equation by 11:
x = 87/11 = 7.909
One solution was found :
x = 87/11 = 7.909
