Answer:

x + y=24  

x=24-y = 3x+5y=100  

3(24-y)+5y=100

72-3y+5y=100

72+2y=100

2y=28

y=14, since x=24-y

x=10

So there are 10 3-point questions and 14 5-point questions.

When converting 750 ounces to pounds what unit would you place in the denominator of your ratio
kumpel [21]

Ounces would be in the denominator of your ratio.

Converting ounces to pounds you would simply divide by 16 :)

Have a great rest of your day! Good luck!

1. A catering company’s recipe for salad uses a ratio of 2 c of dressing to 4 lb of vegetables. (a) Draw a model for the ratio.
IRISSAK [1]
1. ratio = 2 c of dressing / 4 lb of vegetables

Use two variables: d for the number of c of dressing and v for the number of pounds of vegetables.

Then d / v = 2/4 = 1/2 => d = v/2

Now you can make a table

v     d  

2    1

4    2

6    3

8    2

And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2

b) I already did it above as part ot the explanation: d/v = 1/2

What is the answer to 6(x+4)=30
DanielleElmas [232]

Start by distributing the 6 through the parenthses on the left side.

So we have 6x + 24 = 30.

Solving from here, I would subtract 24 from both sides to get 6x = 6.

Finally, dividing both sides of the equation by 6, we have x = 1.
