Answer:
a, c, d, f for sure has a hypotenuse but id-k if e would count
Step-by-step explanation:
So 1 nickle=5 cents
1 quarter=25 sents
q=number of quarters
n=number of nickles so
total is
q+n=20
5n+25q=400 (since 100 cents=1 dollar and 4 dollares=400 cents)
SO THE 2 EQUATIONS WOULD BE
n+q=20
5n+25q=400
so q+n=20
subtract q from both sides
n=20-q
subsitute 20-q for n in the second equation
5(20-q)+25q=400
distribute
100-5q+25q=400
add like terms
100+20q=400
subtract 100 from both sides
20q=300
divide both sides by 20
q=15
thhere are 15 quarters
subsitute 15 for q in first equation
15+n=20
subtract 15 from both sides
n=5
5 nickles
15 quarters
Answer:
x = 3
Step-by-step explanation:
Perform the indicated multiplication, using the distribution rule:
10 + 6x = 4x + 16
Gathering the first powers of x on the left and the constants on the right, we get:
2x = 6, or x = 3
- -- There are 260.714 weeks total in 5 years.
But you can round by doing this:
52*5=260
This is because you have 52 weeks in a year and 55 years so you multiply.
