Answer:
(-2, -4.5)
Step-by-step explanation:
We can solve this equation with substitution.
x=2y+7
3x-2y=3
We can "substitute" 2y+7 for x into the second equation:
3(2y+7)-2y=3
Distribute the 3
6y+21-2y=3
Add like terms
4y+21=3
Subtract 21 from both sides
4y=-18
Divide both sides by 4 to isolate y
y=-4.5
Plug -4.5 back in for y:
x=2(-4.5)+7
x=-9+7
x=-2
(x,y)=(-2,-4.5)
Answer:
17 is the answer.
Step-by-step explanation:
Answer:
X= -50
Step-by-step explanation:
Remove the parenthesis
multiply both sides by two
x - 6 = -56
Move the 6 to the other side
x = -56 + 6
x = -50
The answer is 1.85
To figure this out, think about what we want. We want our original number plus 85% of the original number. The 1 part will give you back your original number, and the 0.85 part will add 85%.
30
factors of 6: 6 12 18 24 30
factors of 5: 5 10 15 20 25 30
so its 30
or simply multiple the denominators 6×5=30
