Hi!
We need to find the value of x by isolating it on one side of one of the equations.
5y = x - 7
Add 7 to both sides.
5y + 7 = x - 7 + 7
5y + 7 = x
Now put the value of x in the other equation.
2y = 5y + 7 + 3
Simplify
2y = 5y + 10
Subtract 5y from both sides.
2y - 5y = 5y - 5y + 10
-3y = 10
Divide by -3 on both sides.
y = -10/3
Now put the value of y in the other original equation to solve for x!
5 * -10/3 = x - 7
-50/3 = x - 7
Add 7 to both sides.
-50/3 + 7 = x - 7 + 7
-29/3 = x
The answer is C.){(-29/3, -10/3)}
Hope this helps! :)

Answer:
Try this example! The link to the actual question is at the bottom.
Step-by-step explanation:
A percent is a portion of 100. If $25 is 100% of the price, and we receive 20% off then we pay 80% of the price. 100%-20%=80%. We find the new price by multiplying 25 by the percent as a decimal. 80% is 0.80.
25(0.80)=$20. The discount is $5 off.
We add tax by using the percent as we did above. Instead of calculating how much we will pay after the discount, we calculate how much the tax percent is in dollars. We take 7.5% and convert to decimal 0.075. We multiply by the price we pay $20.
0.075(20)=$1.50.
We add $1.50 to our total of $20 to pay $21.50.

Answer:
moderate positive relationship
Step-by-step explanation:
From the data:
The linear relationship between score and rating can be obtained by calculating the Pearson correlation Coefficient between the two variables. This can be obtained more easily by using technology, a linear correlation Coefficient calculator. The result of the correlation Coefficient for the data above is about 0.66. This value is positive which shows that the association between the variables is positive, increase in one leads to increase in the other and vice versa. Also the value shows that the relationship is fairly strong.
The largest GCF of both 64 and 40 would be 8
When you do 64/8 you get 8
When you do 40/8 you get 5
SO the final answer is 8:5
Hope this helps
