Mila and samuel had an equal amount of money for shopping. Mila spent $42 and Samuel spent $36. After that, Mila had 1/2 of what
koban [17]

Answer:

Mila had $48 initially

Step-by-step explanation:

Let the amount of money they had be x

Mila spent $42; what is left would be x-42

Samuel spent $36: what is left would be x-36

So, what Mila had left is half of what Samuel has; that would be;

x-42 = 1/2(x-36)

2(x-42) = x -36

2x-84 = x -36

2x - x = 84 -36

x = $48

What does (d+3) represent in 4.5(d+3)=45
Scrat [10]

Answer:

(d + 3) would be 10

Step-by-step explanation:

<u>Step 1:  Distribute</u>

4.5(d + 3) = 45

(4.5 * d) + (4.5 * 3) = 45

4.5d + 13.5 = 45

<u>Step 2:  Subtract 13.5 from both sides</u>

4.5d + 13.5 - 13.5 = 45 - 13.5

4.5d = 31.5

<u>Step 3:  Divide both sides by 4.5</u>

\frac{4.5d}{4.5} = \frac{31.5}{4.5}

d = 7

<u>Step 4:  Determine what (d+3) is</u>

(d + 3)

(7 + 3)

10

Answer: (d + 3) would be 10

How do you know how many places are in fifty million without writing the number in standard form
wolverine [178]
We know that 1 million has 6 zeros. This means 1 million has 7 place values: one for the 1 and 6 for the zeros.

50 has 1 more place value than one, so 50 million has 1 more place value than 1 million.

So, 50 million has 8 place values.
