Minus 9$ from the 13$ after you get the answer then double it you should come out with the correct answer

So to find the answer to this, you have to consider that \frac{1}{2} x + 9 = 13 - half because half the pocket money (x) was spend on clothes, then plus 9 because that's how much extra she gained and 13 because that was the result of all the changes.

To solve this, first subtract 9 from both side, which leaves you with \frac{1}{2} x = 4 and \frac{1}{2} x is the same as \frac{1x}{2}, so to solve this, multiply both sides of the equation by two, resulting in x = 8. SO from this we can conclude that the weekly allowance is $8

If after 45 minutes han cycled for 6 miles and claire cycled for 9 miles what will the difference between them be after 45 minut
IceJOKER [234]

Answer:

The difference between them will be 6.

Step-by-step explanation:

When they went for their first round of cycling, which was 45 minutes, it was already a distance of 3 miles adding another 6 to Han's miles and another 9 to Claire's miles it would give you 18 and 12 and 18 minus 12 is 6.

Therefore, it was doubled from the distance only being 3 miles to 6 miles.

What is the slope of the line shown in the graph?<br> A 3/2<br> B 2/3<br> C -3/4<br> D - 2/3
goldenfox [79]

Answer:

D. -2/3

Step-by-step explanation:

Since it is going down, it is negative

Think of this: Rise/Run

In this case, rise is when you are going up or down the graph

Run is when you are going to the right of the graph

Let's use 2 points (0,3) and (3,1)

Since you are going three points to the right we are going to put 3 in for run

You are going 2 places down, so we are going put -2 in for rise

This gives us -2/3

Another way to do this is (1-3)/(3-0) = -2/3

name three different pairs of fractions that have the same product when multiplied .explain how you got your answer
Deffense [45]
\frac{5}{10}*\frac{10}{40}=\frac{50}{400}
\frac{2}{8}*\frac{2}{4}=\frac{4}{32}
\frac{1}{4}*\frac{1}{2}=\frac{1}{8}

\frac{1}{8} is obtained by multiplying \frac{1}{2} and <span>\frac{1}{4}
</span>You basically create equivelant fractions for both 1/2 and 1/4 and multiply by each other. This way you get the same result always.
