For the following equations, draw a picture of the tiles on an Equation Mat. Then use “legal” moves to simplify and solve for the variable.


a. -2+x = -x+2


b. 2+3x = x+7

Answers

Answer 1
I can solve these for you

a:
-2+x=-x+2
+2 +2
x=-x+4
+x +x
2x=4
— —
2 2
x=2

so the solution to a is x=2


b:
2+3x=x+7
-2 -2
3x=x+5
-x -x
2x=5
__ __
2 2
x=2.5, or 2 1/2

so the solution to b is x= 2 1/2

PLEASE ANSWER QUICKLY I WILL GIVE BRAINLIEST Mrs. Morales wrote a test with 18 questions covering spelling and vocabulary, Spelling questions W) are
worth 5 points and vocabulary questions (y) are worth 10 points. The maximum number of points possible
on the test is 100
Part 1 out of 4
Write an equation in slope-intercept form to represent the number of questions on the test
The equation is y

Answers

Here's our data:

15 questions total

Total number of points: 100

Spelling questions are worth 5 and represented by x

Vocab questions are worth 10 and represented by y

Therefore:

x+y=15

5x + 10y= 100

So:

x+y=15

x= 15-y

5x +10y =100

5(15 -y) +10y =100

75 -5y +10y =100

75 +5y = 100

5y=25

y=5

x +y=15

x+5=15

x=10

There are 10 spelling questions and 5 vocab questions

Help fast Please!!!!! What is the vertical distance between
(-3, -2.5) and (-3, 5)?

Answers

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.

I hope that helps, have a great rest of your day! ^ ^
