$20 a week for 10 weeks is:
20*10 = $200
She spends $6.75 each day for 5 days:
6.75*5 = $33.75.
Lets subtract her spending from her savings to find out how much she has left:
$200-$33.75 = $166.25
Answer:
-600
Step-by-step explanation:
4 x 10 x 3 x 5 x -1
40 x 15 x -1
600 x -1 = -600
Step-by-step explanation:
Given.


Take the second equation and subtract 2y to both sides.


Substitute x into the first equation and simplify.




Invert.

Substitute Y into your second equation.



Add -6 to both sides.


Answer:
(6, -3)
6(-5n+7)=0
We simplify the equation to the form, which is simple to understand
6(-5n+7)=0
Reorder the terms in parentheses
+(-30n+42)=0
Remove unnecessary parentheses
-30n+42=0
We move all terms containing n to the left and all other terms to the right.
-30n=0-42
We simplify left and right side of the equation.
-30n=-42
We divide both sides of the equation by -30 to get n.
n=1.4
