Let's say the diameter of the larger gear is "x".

the small one has a diameter of 16cm, we know that, this is 2.5 more than (1/4)x.

\bf 16=\cfrac{1}{4}x+2.5\implies 16-2.5=\cfrac{x}{4}\implies 13.5=\cfrac{x}{4}\implies 4(13.5)=x

Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.
Slav-nsk [51]

Sample Response: To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

Solve the inequality(s)<br> 2c &gt; 2 <br> d/6 ≥ 1 <br> r + 9 ≤ 23
tatiyna
Divide both sides by 2 for the first one.
2c/2>2/2
c>1
simplify both sides for the second 1 
1/6d>=1
6*(1/6d).=(6)*(1)
d>=6
For the last one 
subtract 9 from both sides
r+9-9<=23-9   so  that r<=14
 Hope this helps!

By what percent will the fraction increase if its numerator is increased by 60% and denominator is decreased by 20% ?
seropon [69]

Answer:

100%

Step-by-step explanation:

Start with x.

x = x/1

Increase the numerator by 60% to 1.6x.

Decrease the numerator by 20% to 0.8.

The new fraction is

1.6x/0.8

Do the division.

1.6x/0.8 = 2x

The fraction increased from x to 2x. It became double of what it was. From x to 2x, the increase is x. Since x was the original number x is 100%.

The increase is 100%.
