18-2x=4x is given
18=6x is addition property of equality
3=x is I think division property of equality bc you divided to get x=3
Answer:
-240
Step-by-step explanation:
Since 20 is right next to -12 that means you have to multiply.
Answer is a right triangle. The angles of a triangle must add to 180 degrees.
You have two 45 degree angles
45 + 45= 90
Now you need 1 more angle to equal 180
180- 90= 90
A right angle is 90 degrees. A right triangle has one right angle and two acute.
Answer:
y = -2x + 14
Step-by-step explanation:
Step 1: Our line is parallel to this line, so it has the same slope, but a different y-intercept, so set up the equation...
y = -2x + b
We are given a point (x, y) of (5, 4), so plug that in and solve for b.
4 = -2(5) + b
4 = -10 + b (simplify)
14 = b (add 10 to both sides to isolate b)
So the equation of our line is y = -2x + 14
68 sq in. You multiply 5 by 12 ( amount of inches in a foot) and get 60, then add the extra eight inches(these inches are from 5.8). Hope this helps :)
