Answer:
Step-by-step explanation:
I haven't got time to do all these by I'll give you the method in each case.
You have to make the x or y term equal (or 1 term + and other -) in both equations before adding or subtracting.
A . Multiply equation 2 by 2 and subtract (to eliminate x)
- don't forget to multiply EACH TERM by 2.
B. Multiply equation 2 by -2 and add.
C. Multiply equation 1 by 3 and equation 2 by 2 ( this will give -6y and +6y in the resulting equations ) so you then add to eliminate y.
D. Multiply equation 1 by 13 and equation and equation 2 by 2 to eliminate x then add.
Okay, so we need to find the price of the original shirt and the discounted shirt with the 5% tax.
5% (into a real number) is .05
Multiply 20.98 and 15.48 by .05
20.98*.05= 1.049 I am going to round to 1.05
15.48*.05= 0.774 I am going to round to .75
Now we know the prices of both, so we subtract them by each other.
20.98+1.05= 22.03
15.48+.75= 16.23
22.03-16.23= 5.80
But since we rounded the numbers, I would go with choice D.
Hope this helps!

There r 8 odd number rooms
Answer:
5 gallons
Step-by-step explanation:
We can use ratios to solve
5/12 gallon x gallons
---------------- = -------------------
1/24 minute 1/2 minute
Using cross products
5/12 * 1/2 = x *1/24
5/24 = x/24
Multiply each side by 24
24*5/24 = x/24*24
5=x
We can pump 5 gallons
