Answer:
19.32
Step-by-step explanation:
One way to find the missing number is to get the value of the left side of the equation first.
8.4(1.5 + 2.3) = 31.92
Now we need to take that value and subtract it to the value on the right side of the equation.
31.92 - 12.6 = 19.32
So we have:
8.4(1.5 + 2.3) = 12.6 + 19.32
31.92 = 31.92
Answer:
The required number is 19.32
Step-by-step explanation:
Consider the provided expression.
Let the missing number is x.
[tex]8.4(1.5 + 2.3) = 12.6 +x[/tex]
Add the numbers as shown.
[tex]8.4(3.8) = 12.6 +x[/tex]
Open the parentheses.
[tex]31.92= 12.6 +x[/tex]
Subtract 12.6 from both the sides.
[tex]31.92-12.6= 12.6-12.6 +x[/tex]
[tex]x=19.32[/tex]
Hence, the required number is 19.32
