A proportional relationship is when you cross multiply, and the numbers are equal. See the first few numbers.

1 x 12 = 12
3 x 4 = 12

Now solve.

3 x 16 = 48
48/12 = 4

20 x 8 = 160
160/5= 32

The first answer is 4, and the second is 32.

Hope this helps! :)

Answer:

4 and 32 are the only ones equivalent since the proportional is 4 times the letter x.

Answer:

Thus, a golden retriever should be given 19 teaspoon of medicine.

Step-by-step explanation:

Given that a golden retriever weighing 85 pounds has diarrhea. His medicine is prescribed as 1 teaspoon per 5 pounds.
To find how much medicine should he be given.
Assign a variable. Write a sentence that gives the information to find it.
Translate into a proportion be careful of the units.
Multiply both sides by the Least Common Denominator and simplify. Check the answer.

Step 1 of 3

Write the data in mathematical form and simplify.

Let x=the number of teaspoon

If 1 teaspoon medicine is 5 pounds then 85 pounds is how many teaspoon of medicine.

Translate the statement into proportion.

$\begin{aligned}\frac{\text { pounds }}{\text { teaspoon }} &=\frac{\text { pounds }}{\text { teaspoon }} \\\frac{5}{1} &=\frac{85}{x}\end{aligned}$

Step 2 of 3

Multiply both sides by x and simplify

$$x(5)=\frac{85}{\bcancel{x}}(\bcancel{x})$

5x=85

Divide by 5,

$x=\frac{85}{5}$

Simplify, x=19

Step 3 of 3

Check the answer.

Substitute x=19 in original proportion and simplify.

$$$\begin{aligned}\frac{5}{1} &=\frac{85}{x} \\5 &=\frac{85}{19}\end{aligned}$\\ \\ Hence, $5=5$, True$

Use a number line to help you find the sum of -24+8

Triss [41]

Answer:

-16

Step-by-step explanation:

When adding a negative and a positive number, you need to keep in mind that your are essentially adding.

so if I have a number line

-24, -23, -22, -21, -20, -19, -18, -17, -16, -15, -14,,,,

you will start at -24 and will go up the number line (to the right) 8 times and that should get you your answer.
