Answer:
true
Step-by-step explanation:
The problem is basically asking you _ x 4 = 50, so, what is 1/4 of 50? (12.5)
X + y = 120000
0.15x - 0.10y = 5500
Multiply both sides of bottom by 100 to remove decimals
x + y = 120000
15x - 10y = 550000
Multiply both sides of top by 10
10x + 10y = 1200000
15x - 10y = 550000
Add the two
25x = 1750000
x = 70000
He paid $70,000 for the property that made a profit, and paid $50,000 for the property that lost value.
Answer:
If 1 pint is equal to 2 cups, then 5 pints would equal _<u>5</u>_ cups.
Step-by-step explanation:
Let's use a ratio to solve:
pints : cups
1 : 2
2 : 4
3 : 6
4 : 8
5 : 10
There would be 10 cups in 5 pints.
K=4
add seven on both sides
2x-4y=7
add 4y on both sides
2x=7+4y
divide 2 on both sides
x=7+4y/2
plug that into original equation
2(7+4y/2)-4y-7=0
7 and 4y cancel out
2(2)=0
4=0
