Answer:

477

Step-by-step explanation:

It's pretty simple. All you need to calculate is how much they made in the 9 hours. So multiply 58 x 9 and you get 522. Then take away what they didnt make, which was 45. That gives you 477.

Answer:

A) B. 18-6

B) 20÷4

C) 20

Step-by-step explanation:

Part A

The order of operations tells you that the first step is to evaluate any expressions in parentheses. Here, that means you first evaluate (18 -6).

Part B

After parentheses have been removed, the next step is to perform multiplication and division. Here, there is only one term involving division, so you divide 20 by 4 as your second step.

Part C

After you have done parts A and B, your expression is ...

3 + 12 + 5

The value of this sum is 20.

Answer:

$\large\boxed{19\dfrac{17}{20}}$

Step-by-step explanation:

$\text{First step:}\\\\\text{Find LCD}\ (Least\ Common\ Denominator)\\\\LCD=20\\\\4\cdot5=20\\5\cdot4=20\\\\\dfrac{1}{4}=\dfrac{1\cdot5}{4\cdot5}=\dfrac{5}{20}\\\\\dfrac{3}{5}=\dfrac{3\cdot4}{5\cdot4}=\dfrac{12}{20}\\\\9\dfrac{1}{4}+10\dfrac{3}{5}=9\dfrac{5}{20}+10\dfrac{12}{20}=(9+10)+\dfrac{5+12}{20}=19\dfrac{17}{20}$
