Solve for r 5(r-10)=-51
Pie

Answer:

r=−1/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(r−10)=−51

(5)(r)+(5)(−10)=−51(Distribute)

5r+−50=−51

5r−50=−51

Step 2: Add 50 to both sides.

5r−50+50=−51+50

5r=−1Step 3: Divide both sides by 5.

5r/5=−1/5

r=−1/5

How can mental math help you find solutions to inequalities?
shepuryov [24]

Answer:

There are many examples the basics are also easy to remember.

Step-by-step explanation:

We can input these for the following equation.

x > 5

(x is greater than 5)

Then compare to - x < 5

(minus x is less than 5)

We try a sum

3x -2 ≤ 1

we can then balance subtract -2

3x ≤ -1

then divide by 3

x= -1 /3

We try another value

3x -2 ≤ 0

1 ≤ 3x

1/3 ≥ x

We can check that each equality fits and alter the number accordingly.

For the first one we are saying it is no greater than 1

For the second we say it is greater than zero.

We are able to prove both have the answer.

Just like when we look for negative percentages and count down we record this as we count in mental math.
