Answer:

x=3, y=-1

Step-by-step explanation:

We know that lcm(7, 2)=14, so we need to multiply equation 1 by 2.

This gives 2(4x-7y)=2(19), which simplifies to 8x-14y=38.

We know that lcm(2, 7)=14, so we need to multiply equation 2 by 7.

This gives 7(3x-2y)=7(11), which simplifies to 21x-14y=77.

Aha! Now we have a path to the solution!

We can subtract the first equation from the second to eliminate y.

This gives (21x-14y)-(8x-14y)=(77)-(38), which simplifies to 13x=39.

We can then divide by 3 to obtain x=3!

Then, we plug x=3 into the second equation to get 3(3)-2y=11.

We can subtract 9 from both sides to get -2y=2.

We then divide by -2 to obtain y=-1.

So, x=3 and y=-1, and we're done!

A sweater originally priced at $80 was marked down by 25%. What was the sale price of the sweater?
crimeas [40]
The original price of the sweater is $80 which is 100% of the price.
If the price is reduced by 25%, then the new price is 75% of the original price since 100% - 25% = 75%.
Now we need to find 75% of $80.

To find a percent of a number, multiply the percent by the number.
To convert a percent into a decimal, divide the percent by 100 which is the same as moving the decimal point two places to the left.

Here's how to change 75% into a decimal.
75% = 75/100 = 0.75

Here's how you calculate 75% of $80.
75% of $80 =

= 75% * 80

= 0.75 * $80

= $60

Answer: The sale price is $60.
