What does the variable r represent in the equation 10r+4=8

Kryger [21]

Answer:

The value of variable r in the equation $10r+4=8$ is $\mathbf{r=0.4}$

Step-by-step explanation:

We need to find the value of variable r in the equation $10r+4=8$

Step 1: Write the equation

Step 2: Subtract 4 on both sides

$10r+4-4=8-4\\10r=4$

$\frac{10r}{10}=\frac{4}{10}\\r=0.4$

So, The value of variable r in the equation $10r+4=8$ is $\mathbf{r=0.4}$

Answer: for -10 + 4 the answer is -6

for -7 - 11 the answer is -18

Step-by-step explanation:

For -10+4 all you do is start at -10 and go up 4 to -6 (-9, -8, -7, -6)

and for -7 - 11 you start at 7 and just go down (but the numbers get bigger) to -18 (-8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18)
