Solve 7r+ 2 = 5(r – 4) ​
AveGali [126]

Multiply the bracket by 5

I used PEMDAS

P= parenthesis

E= exponents

M=multiplication

D= division

A= addition

S= subtraction

7r+2= 5(r-4)

7r+2= 5r-20

Move 5r to the left hand side . Positive 5r changes to negative 5r

7r-5r+2= 5r-5r-20

2r+2=- 20

2r+2-2= -20-2

Move positive 2 to the right hand side. Changes to negative -2

2r+2-2= -20-2

2r= -22

Divide by 2 for 2r and -22

2r/2= -22/2

r= -11

Answer is r= -11

The blue dot is at what value on the number line?<br><br><br>10 +<br><br><br>2.
NikAS [45]

Answer:

-10

Step-by-step explanation:

We can figure out that the number line is by four.

How?

There is one line between 10 and 2. Sooo:

10 - 2 = 8

8 / 2 = 4

If we check it (10 - 4 - 4 = 2) it checks out!

Using this information we can figure out what the blue dot is.

2 (given) - 4 (incriments of number line) - 4 - 4 = - 10

There is our answer, -10!
