Answer:

169 $cm^{2}$

Step-by-step explanation:

= 54 + 115

SA = 169 $cm^{2}$

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

$10r+4=8$

Step 2: Subtract 4 on both sides

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

Step 3: Divide both sides by 4

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

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