Answer:

x = # of 5 cent coins

y = # of 50 cent coins

x+y=25

.05x+.5y=7.1

y=25-x

(.05x+.5(25-x)=7.1)100

5x+50(25-x)=710

5x+1250-50x=710

-45x=-540

x=12

You have 12, 5 cent coins and 13, 50 cent coins.

I’m stuck and I would really like your help.
Neporo4naja [7]

Answer:

Answer: 1/12

Step-by-step explanation:

2/5x-4=8-3/5x.

We want to tank x out of the denominator by multiplying x on both sides.

2/5-4x=8x-3/5

Now we simplify

-12x=-1

x=1/12

Put x in the equation to check it

What is 82,119 rounded to the nearest ten thousand?
Stels [109]
80,000.
To round up to the nearest ten thousand, we would see if the next lower place value has a amount either 5 or higher or 4 or lower.
If it’s five or higher, we round up.
If it’s four or lower, we round down.
We can see that the number in the ten thousands place is 8. The number in the place value after 8 is 2.
2<5 so we round down.
The answer is 80,000.
Hope this helps!
