X-y=50 and 2x=3y
x=y+50 so 2(y+50) = 3y
2y+100=3y
y=100
x-100=50
x=150
so our numbers are 150 and 100
150-100=50 and 150 is 3*50 and 100 is 2*50 so fits all requirements!
hope this helps you! thank you!
Answer:
8 oranges will cost $2.80.
Step-by-step explanation:
2.45/7=0.35
2.45+0.35=2.80
D=√(1.5)(1.4)
d= √6
d= 2.44948.....
Rounded to the nearest tenth would be c. 2.4 mi
Answer:
x = - 3
y = - 2
Step-by-step explanation:
Start with the second equation. Switch
3y = 2x Divide by 3
3y/3 = 2x/3
y = 2x/3
Now go to the first equation. Put the value for y in the first equation.
x - 3(2x/3) = 3 Cancel the 3s on the left.
x - 2x = 3 Combine
-x = 3 Multiply by -1
-1(-x) = 3(-1)
x = - 3
Now go back to the original equation I have called the second equation
2x = 3y
2(-3) = 3y Put in - 3 for x
- 6 = 3y Divide by 3
-6 / 3 = y
y = - 2
I think the answer is $560
working:
$875 * 64% = $560
