What is 7•8+1•40. Explain your answer

zaharov [31]

Answer:

Step-by-step explanation:

We will use the order of operations to solve the equation

7×8+1×40

multiplication before addition, so we do this first:

7×8=56

We change the equation to this:

56+1×40

Then we multiply:

1×40=40

We change the equation to this:

56+40

Then we add to solve:

56+40=96

➷ T $\boxed{4}$ B $\boxed{24}$

✽ Ok, so B is the number of boys and T is the number of teachers.

➷ $t \div ( B + 18) = \frac{2}{21}$

$\frac{B}{18} = \frac{4}{3}$

✽ Then solve the second equation for B.

➷ $B = 24$

✽ Plug into the first equation to find T.

➷ $T \div (24 + 18) = \frac{2}{21}$

$T = 4$

✽

➶ Hope This Helps You!

➶ Good Luck (:
