Answer:
X=1
Step-by-step explanation:
I’m guessing that this is for systems of equations?
n - nickels
d - dimes
These are the equations you start off with.
n = 5d-2
0.95 = 0.10d+0.05n
Substitute the top equation for n into the variable n in the bottom equation.
0.95 = 0.10d+0.05(5d-2)
Solve for d.
0.95 = 0.10d+0.25d-0.10
1.05 = 0.35d
3 = d
Substitute d into the top equation and solve for n.
n = 5(3)-2
n = 15-3
n = 12
There are 3 dimes and 12 nickels in the coin purse! Hope this helped <3
Yes that is a repeating decimal the answer would be -0.4444444.. and so on.
The probability of rolling a 1 or an even number is 5/8.
If there are 8 sides of the die from numbers 1-8, the numbers of the probability are 1, 2, 4, 6, and 8. That makes 5 numbers out of 8 possible numbers. So, the probability is 5/8.(62.5%)
<u>Final Answer:</u>
x = 20
<u>Step-by-step explanation:</u>
we'll be using the pythagorean theorem method, in this triangle the missing letter is a.
formula: 
a = x
b = 21
c = 29
a = 
a = 
(note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)
a = 
a = 20
x = 20
