Joan has raised $306 by selling 34 equally priced boxes of chocolate for the team fund-raiser. Which of the following equations

can be used to find the price, n, of each box of chocolate?
n divided by 34 = 306

34n = 306

n - 34 = 206

n + 34 = 306

34n = 306 can be used to find the price, n, of each box of chocolate.
306/34 = 9
34 x 9 = 306

To solve this problem you must apply the proccedure below:

1. Let's call:

x: hot dogs.
y: hamburguers.

2. Then, you must make a system of equations, as below:

5x+4y=12.25 (i)
4x+5y=12.50 (ii)

3. Now, you can solve the system of equation as below:

5x+4y=12.25
x=(12.25-4y)/5

4x+5y=12.50
4((12.25-4y)/5)+5y=12.50
y=1.5

4x+5y=12.50
4x+5(1.5)=12.50
x=1.25

4. Therefore, the answer is:

The cost of one hot dog is $1.25 and the cost of one hamburguer is $1.50

I have no idea what I am doing. Here is one of my problems,

Alisiya [41]

You need to set up a linear graph. One side with gallons and the other with dollars. Point 1 will be at (1500, 2.10). Point 2 (1300, 2.95). Draw a straight line through these points in your graph and your graph will then give you the answers to your other questions.

Which pairs of points would result in a line with a rate of change of 2:1? Select all that apply.

Helen [10]

Answer:

Options A, C, D are true.

Step-by-step explanation:

We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.

A. The points are (-4,-11) and (-2,-7).

Then the slope of the joining line is $\frac{-7-(-11)}{-2-(-4)} =2$

B. The points are (5,6) and (-5,12).

Then the slope of the joining line is $\frac{12-6}{-5-5} =-\frac{3}{5}$

C. The points are (0,-3) and (-4,-11).

Then the slope of the joining line is $\frac{-11-(-3)}{-4-0} =2$

D. The points are (0,-3) and (5,7).

Then the slope of the joining line is $\frac{7-(-3)}{5-0} =2$

Therefore, options A, C, D are true. (Answer)

Jay is letting her bread dough rise. After three hours, her bread dough is \dfrac{11}{5} 5 11 start fraction, 11, divided by,

timama [110]

Answer:

Jay's bread size is 220% of the original size.

Step-by-step explanation:

The question is incomplete.

The complete question is as follows.

Jay is letting her bread rise. After 3 hours,her bread is at 11/5 of its original size. What percent of its original size is jays bread dough?

Solution:

Let the original bread size be = $100$ units

After 3 hours the bread rises = $\frac{11}{5}$ of the original size

New size of bread = $\frac{11}{5}\times 100=220$ units

Percent of original size the new bread is

⇒ $\frac{New\ bread\ size}{Original\ bread\ size}\times 100$

⇒ $\frac{220}{100}\times100$

⇒ $220\%$
