Answer: </h3><h3>
There are 75 coins that aren't nickels. </h3><h3>
One equation you could use is 75+n = 92</h3>
(This solves to n = 17 meaning there are 17 nickels)
=====================================================
Explanation:
"There are 25 pennies, 21 dimes, and 29 quarters", so there are 25+21+29 = 75 coins so far. This is the amount of coins that aren't nickels. The rest are nickels, which is some amount n. This adds to the 75 to get 75+n. Set this equal to 92 because there are 92 coins in all. That's how we end up with 75+n = 92.

Extra info
The equation 75+n = 92 is the same as n+75 = 92. Subtract 75 from both sides to isolate n. You should get n = 17 after doing so.

=11/3×1/14
=3.67×0.07
=0.2568
D 1/2 because half the dice is odd and half is even
Answer:
<h2>
x = 20.8</h2><h2>
y = 22.3</h2>
Step-by-step explanation:
- x is the adjacent side
- 8 is the opposite side
- y is the hypothenuse
SOH - CAH - TOA
Since the opposite side is given and we need to find the length of the adjacent side, we can use tangent to solve for x.
Since the opposite side is given and we need to find the length of the hypotenuse, we can use sine to solve for y.
