A can contained 5.5 ounces of tuna. Joey used 2.88 ounces of the tuna to make a sandwich. To find the amount of tuna remaining in the can, Joey subtracted as shown below: Is Joey's work correct? Explain how you can tell if his work is correct.

Answers

Answer:

Yes

Step-by-step explanation:

A full can of tuna has a certain amount in it, if a portion is removed from the can it is therefore subtracted from the total amount. This means that Joey's work is correct and the tuna can would have

5.5 oz - 2.88 oz = 2.62 oz

The best way to tell if his work is correct would be to weigh the remaining tuna in the can and see if it matches Joey's answer.

what is x in 6x - 4 = 8 ( 2 +1/4 x)

Answers

Answer:

Step-by-step explanation:

move the terms 6x-4=16+2x

collect like terms 6x-2x=16+4

divide both sides 4x=20

x=5

Answer:

x = 5

Step-by-step explanation:

6x - 4 = 8( 2 + 1/4x) Distribute

6x - 4 = 16 + 2x

-6x -6x Subtract

-4 = 16 - 4x

-16 -16 Subtract

At the grocery store, you can buy gum in a 6 pack for $11.70 or a 12 pack of gum for $23. Which is the better deal and what is the price per pack of gun if the better deal?

It costs $13 to order a cheese pizza and $2 for each extra topping. Write an equation for the function that gives the total cost y in dollars for ordering a pizza with x extra toppings.
Using the equation from question 5. Complete the table.
Extra Toppings X Total Cost (S) Y: Blank, blank, blank
3
4
5

Answers

Answer:

y = 2x + 13

Step-by-step explanation:

total cost of pizza (y) = price of cheese pizza + price ($2) of each added topping (x)

we can start by looking at y = 13 the total cost (y) of a CHEESE pizza is $13

If you want to ADD additional toppings, you pay $2 for each topping. We know how much each topping is, but we are not sure how many additional toppings we need. So x will represent how many toppings are added. We can multiply $2 times how many toppings to figure out the additional cost of the toppings.

y = 13 + 2x ; remember, function form is y=mx+b so re-write the equation as

y = 2x + 13

I am unsure why the 3, 4, and 5 are listed here, but if the problem is asking you to solve for how much your pizza will cost with 3 toppings, 4 toppings, and 5 toppings, you will need to use substitution to solve for the cost.

y = 2x + 13

y = 2(3) + 13

y = 6 + 13

y = 19

If you order a pizza with three additional toppings, your total cost will be $19.
