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}

83 tens × 2 tens =166
FinnZ [79.3K]
1 cube= 1 unit
1 Rod (Long)= 10 units
10 Rods (Longs)= 1 flat (1 flat=100 units)
10 flat =1 cube(1 cube=1000 units)
83×10= 830
2×10=20
830×20= 16,600
Just wanted to add more to help you understand why 83 is multiplied by ten and 2 is multiplied by 10. Its because when we use Base ten blocks, tens represent 1 Rod (Long)= 10 units. Hope it helps more.
