Subtract four from both sides. That'll put both numbers without a variable on one side, and the number with the variable is by itself.
Answer:
4
Step-by-step explanation:
For this problem, we are trying find the output of when plug in -3 into 2x+10:
f(-3)=2(-3)+10=-6+10=4
Answer:
x = 8/3
y = 7/3
Step-by-step explanation:
In a parallelogram the diagonals bisect each other.
So 2x = y + 3
x + y = 5
Then you set them up to do combination/elimination to solve for the two variables.
2x-y = 3
Then you add the two equations together
3x = 8
Solve for x
x = 8/3
Then solve for y by plugging it into a equation
x + y = 5
8/3 + y = 5
8/3 - 5 = -y
8/3 - 15/3 = -y
-7/3 = -y
y = 7/3
Answer:
<h2>$4.85</h2>
Step-by-step explanation:
John spent and gave to his two friends a total of
1.25 + 1.20 + 1.20 = $3.65
