Answer:

Step-by-step explanation:

you want to create two equations for each situation so if v=number of students that can fit in a van and c=number of students that can fit in a car then you can create the equations 3v+1c=22 and 2v+4c=28

then you want to make both equations equal to c

so for the first one you subtract both sides by 3v and you get c= -3v+22

and for the second one you subtract 2v from both sides and end up with 4c=-2v+28 and then divide both sides by 4 leaving you with c= -1/2v+7

then you make both of those equations equal to each other and solve for v

so -3v+22= -1/2v+7 and you end up with v=6

therefore, each van can hold 6 students

$length = 3x - 5 \\ width \: = x \\ p = 2l + 2w \\ 54 = 2(3x - 5) + 2x \\ 54 = 6x - 10 + 2x \\ 54 = 8x - 10 \\ 64 = 8x \\ x = 8 = width \\ 3(8) - 5 = 24 - 5 = 19 \\ length = 19$

jeyben [28]

Answer:

x/2=87.2

Step-by-step explanation:

Pip was thinking of a number - Let's call this number x

Pip halve the number - So half of x = x/2 (or 1/2 x)

And gets an answer of 87.2 - x/2=87.2

So your equation would be x/2=87.2

I hope this helps :)

Alchen [17]

Amount of money Aisha receive from selling all of the bracelets is $33.25.

<u>Step-by-step explanation:</u>

In this question, its given that Aisha made bracelets for a craft fair. She spent $29.75 on supplies to make the bracelets. Each bracelet cost her about $0.85 to make. Aisha sells each bracelet for $0.10 more than it cost her to make. Let's calculate Number of bracelets Aisha made as $\frac{total-cost}{cost-of-one-bracelet}$ .

Number = $\frac{total-cost}{cost-of-one-bracelet}$

⇒ Number = $\frac{total-cost}{cost-of-one-bracelet}$

⇒ Number = $\frac{29.75}{0.85}$

⇒ Number = $35$

Now , its given that Aisha sell these bracelets with $0.10 more then it cost her i.e. at $0.95 , Let's calculate selling price as :

Price = $0.95(35)$

Price = $33.25

Therefore, amount of money Aisha receive from selling all of the bracelets is $33.25.
