This is the answer key, not my work. For question 7, how do you get the -3 and 2 to multiply the equations by

1 answer:

5 0

The -3 and 2 are just the numbers you multiply by to get the variable 's' have opposite values in the 2 equations so that when you add the 2 equations, they would cancel out

How many coins did julia collect

kondor19780726 [428]

Answer:

The number of coins Julia found is 5

Step-by-step explanation:

We know that the total number of gold coins collected divided by the number of people collecting is 6. So we can set up an equation:

$\frac{6+5+6+8+x}{5}=6$

this simplifies to:

$\frac{25+x}{5}=6$

Using the multiplication property of equality and multiplying both sides by we get:

25+x=30

Then finally, using the subtraction property of equality we get our answer:

x=5

The owner of a souvenir shop wants to order some custom printed mugs and t-shirts what is the price per t-shirt for 75 T-shirts

lara31 [8.8K]

Answer:

The price per t-shirts is $8.5.

Step-by-step explanation:

Let us assume the price per t- shirt = $m

The cost of 75 t-shirts = $637.50

Now, the total cost for 75 t-shirts = 75 x ( cost of 1 t-shirt)

⇒ $637.50 = 75 x ( m)

⇒ m = $637.50 / 75

or, m = 8.5

Hence, the price per t-shirts is $8.5.
