Answer:
4
Step-by-step explanation:
In this question, you would be solving the expression by combining like terms.
Solve:
(5a + 3b - 6c) - (20 - 4b + 13c)
Distribute the negative to the variables inside the parenthesis.
5a + 3b - 6c - 20 + 4b - 13c
Combine like terms.
5a + 7b - 6c - 20 - 13c
5a + 7b - 19c - 20
You can't combine anymore like terms now, so your answer would be 5a + 7b - 19c - 20
Answer:
5a + 7b - 19c - 20
Step-by-step explanation: B
put the center of the circle on the right of the line and the edge of the circle on the p. Make part of a circle. you dont have to do the whole circle, but you can if you want.
do the same thing again but on the other side of the line.
now it should look like the first image i included (if you didnt do the whole circle)
now take your straightedge/ruler/line maker and make it go through the intersecting points on the circles, like the second image.
Note that my images are for demonstration. They're not perfect at all, they're just to show you how to do it.
Another way to write the expression the answer is this (t.14)-(t.5)
