Answer:

G -21

Step-by-step explanation:

m /28 = -27/36

We can solve using cross products

m*36 = -27 * 28

36m = -756

Divide each side by 36

36m/36 = -756/36

m = -21

Answer: -21

Step-by-step explanation:

M/28=-27/36

Looking at the above equation, you will solve using cross multiplication

36×m=28×-27

M= 28×-27/36

M= -756/36

M= -21

The correct option is G

Given the diagram below, find the height of the shorter tree.
rusak2 [61]

Answer:

h = 13 m

Step-by-step explanation:

The triangles are similar, so the ratios of corresponding sides are equal, that is

\frac{h}{39} = \frac{16}{48} = \frac{1}{3} ( cross- multiply )

3h = 39 ( divide noth sides by 3 )

h = 13

kvv77 [185]

Answer:

Step-by-step explanation:

1 ring has a radius of 3 feet

1 ring has a circumfrence of 2*pi*r = 2 * 3.14 * 5 = 10*Pi

5 rings would have a length of 50 * pi length = 50*3.14 = 157 feet

- 6x +15 <br>Can anyone please show me the steps of solving this equation​
Vesna [10]

Answer:

-6x + 15 = - 69 which x = 14

Step-by-step explanation:

You cannot solve this equation. There is no equal sign anywhere. Either you mean

-6x = 15 in which case the answer is

-6x/-6 = 15/-6

x = - 2 1/2 or x= - 2.5

or you mean that you use the distributive property

- 3(2x + 5)

You may have left something out of this.

-6x + 15 = -  69

You can do it now that you have the complete equation. But you need the entire equation before you can answer the question.

Subtract - 15 from both sides.

-6x + 15 - 15 = -69 - 15

-6x = - 84

Divide by - 6

-6x/-6 = - 84/-6

x = 14

But what you want is

-6x + 15

-6*14 + 15

-84 + 15

-69

-6x + 15 = - 69

when x = 14 which is usually what you are asked.

If y = 124 and x = 12, find y when x = -24.
tatyana61 [14]

Answer:

y = -248

Step-by-step explanation:

Hi there!

Set up a proportion:

\displaystyle\frac{124}{12} =\frac{y}{-24}

Cross-multiply:

12y=(-24)(124)\\12y=-2976\\y=-248

I hope this helps!
