What is -7+4m+10=15-2m=

Mathematics
1 answer:
Inessa [10]3 years ago
5 0

Answer:

m=2

Step-by-step explanation:

Add the numbers

-7+4m+10=15-2m

3+4m=15-2m

Rearrange terms

3+4m=15-2m

4m+3=15-2m

Rearrange terms

4m+3=15-2m

4m+3=-2m+15

Subtract 3 from both sides of the equation

4m+3=-2m+15

4m+3-3=-2m+15-3

Simplify

4m=-2m+12

Add 2m to both sides of the equation

4m=-2m+12

4m+2m=-2m+12+2m

Simplify

6m=12

Divide both sides of the equation by the same term

6m = 12

6m/6 = 12/6

Simplify

m = 2

I NEED HELP ASAPPP!!!! It’s urgentttttt!!!!
Akimi4 [234]

Answer: (x - 2)² + (y - 14)² = 1

Step-by-step explanation:

<u>Concept:</u>

Here, we need to know the idea of the circle formula.

Circle formula: (x - h)² + (y - k)² = r²

Center = (h, k)

Radius = r

If you are still confused, please refer to the attachment below for a graphical explanation.

<u>Solve:</u>

Center = (2, 14)

Radius = 1

<em>Given formula</em>

(x - h)² + (y - k)² = r²

<em>Substitute the value into the formula</em>

(x - 2)² + (y - 14)² = (1)²

<em>Simplify</em>

(x - 2)² + (y - 14)² = 1

Hope this helps!! :)

Working together, it takes two different sized hoses 20 minutes to fill a small swimming pool. If it takes 30 minutes for the la
Anuta_ua [19.1K]

Answer:

60 minutes for the larger hose to fill the swimming pool by itself

Step-by-step explanation:

It is given that,

Working together, it takes two different sized hoses 20 minutes to fill a small swimming pool.

takes 30 minutes for the larger hose to fill the swimming pool by itself

Let x be the efficiency to fill the swimming pool by larger hose

and y be the efficiency to fill the swimming pool by larger hose

<u>To find LCM of 20 and 30</u>

LCM (20, 30) = 60

<u>To find the efficiency </u>

Let x be the efficiency to fill the swimming pool by larger hose

and y be the efficiency to fill the swimming pool by larger hose

x = 60/30 =2

x + y = 60 /20 = 3

Therefore efficiency of y = (x + y) - x =3 - 2 = 1

so, time taken to fill the swimming pool by small hose = 60/1 = 60 minutes

natali 33 [55]

Answer:

250 minutes with the flat rate of $29.

x\leq 250

x would be the number of minutes called.

x-250

Tracy would be charged by $0.35 per minute.

f(x)=29\\ 0\leq x\leq 250

f(x)=0.35(x-250)+29,\\250\leq x\leq ∞
