Sidana [21]4 years ago

Answer:

<h2>14.7 Trees</h2>

Step-by-step explanation:

We solve this using a proportion.

\frac{10.5}{5} = \frac{x}{7}

10.5 x 7 = 73.5

5x = 73.5

x = 14.7

Now let's check the proportion.

\frac{10.5}{5} = \frac{14.7}{7}

10.5 x 7 = 73.5

14.7 x 5 = 73.5

73.5 = 73.5 ✅

I'm always happy to help :)

If y varies inversely with x, and y=8 when x=10 find x when y=4
lana66690 [7]

Answer:

x = 4

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 8 when x = 10

k = yx = 8 × 10 = 80

y = \frac{80}{x} ← equation of variation

When y = 4, then

4 = \frac{80}{x} ( multiply both sides by x )

4x = 80 ( divide both sides by 4 )

x = 20

a local hamburger shop sold a total of 424 hamburgers and cheeseburgers. the number of cheeseburgers sold was three times the nu
Vedmedyk [2.9K]

Answer:

There were 318 cheeseburgers sold and 106 hamburgers sold.

Step-by-step explanation:

h = hamburgers

c = cheeseburgers

<u>C = 3h                                                  </u>

An equation would be: 424 = 3h + h.

424 = 3h + h

424 = 4h                                               Add 3h and h together

106 = h                                                  Divide both sides by 4

<u>106 x 3 = </u><u>318                                        </u><u>This is cheeseburgers sold</u>

Checking:

<em>C = 3h</em>

318 = 3h                                                Divide both sides by 3

106 = h

Hope this helps,
