pashok25 [27]

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.

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!

A motorist is pumping gas into his car at a rate of 5/12 of a gallon every 1/24 of a minute. At this rate, how many gallons of g
kirill115 [55]

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
