<span>A golf ball can travel 170 mph. This is 10/7 times the fastest speed recorded for a hockey puck. What is the record speed for a hockey puck? Make an equation and solve.
</span>The speed of hockey puck = x
<span>(10/7)x = 170 </span>
<span>10x = 1190 </span>
<span>x = 119 mph</span>
I'm pretty sure if the answer accepts decimals, if two apples = 175 grams, then one apple equals 87.5 grams, and if we want an apple that equals four grams, it would be less than one apple so we would divide the grams of one apple till it equals 4, therefore 87.5/4 = 21.875
P.S. im not entirely sure this is right im just trying to help :)

Answer:
5 felt pads.
7 cards.
Step-by-step explanation:
Remark
- The total number of items is 12
- So let the felt sheets be x
- Let the cards = y
Equations and Solution
x + y = 12
Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.
0.5x + 0.75y = 7.75 Multiply this equation by 2
x + 1.5y = 15.50 write the first equation underneath and subtract.
<u>x + y = 12</u>
.5y = 3 Divide by 0.5
y = 3/0.5
y = 7
So she can get 7 cards.
x + y = 12
x + 7 = 12
x = 12 - 7
x = 5
So she can buy 5 felt pads.
Is answer is 80% because you move the decimal to the right 2 times
