Y=1/2x+2
y=-x+5
subsitute since they both equal y
1/2x+2=y=-x+5
1/2x+2=-x+5
subtract 2 from both sides
1/2x=-x+3
multiply both sides by 2
x=-2x+6
add 2x to both sides
3x=6
divide both sides by 3
x=2
subsitue
y=-x=5
y=-2+5
y=3
x=2 and y=3
solution in (x,y) form is (2,3)
Hey it would be true i had the same question on a test
Answer:
35 one-dollar bills
18 ten dollar bills
Step-by-step explanation:
We can solve this problem by using logic. First we have to understand that if all the 53 bill were $10 bills, then the combined monetary value would be...
53 x $10 = 530$
Now we start to replace the $10 bills with 1$ and each time we replace 1 bill, the combined monetary value will decrease by...
$10 - $1 = $9
We also know that we need to decrease the combined monetary value all the way to $215, which mean there has to be...
(530 - 215) / 9 = 35 one dollar bills.
And now since we know there are 35 one-dollar bills, that means there has to be...
53 - 35 = 18 ten dollar bills
Answer:
<u>6.975 pints of blue paint</u>
