Help quick! i will give you 20 points. You have 412 pints of ice cream for your birthday party. If you are going to serve 34 pint to each guest, how many guests will you be able to serve?

Answers

Division word problems often ask you to split something evenly. You should solve this problem by dividing the total amount of ice cream by the amount you will serve each guest. After converting to fractions, 4.5 divided by .75. You will have enough to serve six guests, and no ice cream left over.

Step-by-step explanation:

Divide each term by  [tex]8x+ 7[/tex]  and simplify.

Hope this helps :)

-ilovejiminssi♡

a(8x + 7) = 4x + 3.5

8ax + 7a = 4x + 3.5

equating coefficients of x : 8a = 4  so a = 1/2

also 7a = 3.5 so a = 1/2

The value of a is 1/2

You call your teacher and find out that the second part of the note should have said “sell four hot dogs and two bags of chips for $10.” What does that do for your system of equations now? With this new information, how much should each item cost? Again, show all of your work.

Answers

Answer:

h = $4 a hotdog

c = $2 bag of chips

Step-by-step explanation:

3h + c = 14

2h + c = 10

3h + c = 14

-2h - c = -10

h = $4 a hotdog

2(4) + c = 10

8 + c = 10

c = $2 bag of chips

Answer:

h = $4 a hotdog

c = $2 bag of chips

Step-by-step explanation

3h + c = 14

2h + c = 10

3h + c = 14

-2h - c = -10

h = $4 a hotdog

2(4) + c = 10

8 + c = 10

c = $2 bag of chips

Finding the slope:
Identify the slope on the graph below.​

Answers

3/2 is the slope of the graph

Answer:

[tex]\frac32[/tex]

Step-by-step explanation:

Hello!

Slope can be calculated by [tex]\frac{Rise}{Run}[/tex].

The Rise of the graph is how much the graph changes in y between two points.The Run of the graph is how much the graph changes in x between two points.

I'll pick points (0,-2) and (2,1) on the graph.

You can see that the difference in y (-2 and 1) is 3 units.

The difference in x (0 and 2) is 2 units.

Put it into the format and you get a slope of [tex]\frac32[/tex].
