Answer:

2x−5y=12

y = 2/5x + −12/5

Answer is x = 5/2y + 6 because....

First,  Add 5y to both sides.

2x − 5y + 5y = 12 + 5y

Then, Divide both sides by 2.

\frac{2x}{2} = \frac{5y+12}{2}

Therefor, your answer is going to be x = 5/2y + 6

* Hopefully this helps:) Mark me the brainliest:)!!!

<u>Answer:</u>

2/5

<u>Step-by-step explanation:</u>

We are given the following equation of a line and we are to tell the slope of the line:

2x-5y=12

We know that the standard equation of a line is given by:

y = m x + c where m is the slope of the line.

So re-writing the given equation in the standard form:

y=\frac{2}{5} x-\frac{12}{5}

Therefore, 2/5 is the slope of the line.

Nadusha1986 [10]

Answer:

16 years old

Step-by-step explanation:

Let's use the letters s, b, and c for Sushil, Brian, and Caroline's ages. Sushil is the oldest, followed by Brian, and then Caroline, the youngest. From the problem description, we can set up three equations:

s = b + 6 <em>(Sushil is 6 years older than Brian)</em>

c = b - 5 <em>(Caroline is 5 years younger than Brian)</em>

s + b + c = 64 <em>(The total of their ages is 64)</em>

Since s and c are already in terms of b, we can substitute them into the last equation and solve to find Brian's age:

(b + 6) + b + (b - 5) = 64

3b + 1 = 64

3b = 63

b = 21

Now that we know Brian's age, we can simply subtract 5 to find Caroline's:

c = b - 5 = 21 - 5 = 16 years old.

Svetach [21]
Equations:

100 + 35m
50 + 35m

Steps:
100 + 35m = 50 + 35m <span>

<em>Set the equations equal to each other.</em>
</span>   <span />
<span>
100 + 35m = 50 + 35m <span>
-50              - 50
</span>
<em>Subtract 50 from both sides of equation to isolate the variable on one side</em>.

50+35m=35m
     -35m  -35m

<em>Subtract 35m from both sides of equation.</em>

50=m

In fifty months, they will have the same amount of money. They will each contain $1850 dollars.

Hope this helps.

Answer:

2.  92 ounces of Sprite

3.  1/6 do not want mustard on their ham sandwiches

4.  6 hours playing volleyball

5. 32 portions

Step-by-step explanation:

2.  Sam has 8 cans of Sprite.  Each can is 11 2/4 ounces

We can simplify 2/4 to 1/2

Multiply the number of cans by  the ounces per can

8 * 11  1/2

8 * 11.5

92 ounces

3.  1/2 of the students want ham.  1/3 of those do not want mustard

We multiply 1/2*1/3 = 1/6

1/6 of the students do not want mustard on their ham sandwiches

4.  8 hours at the beach.  3/4 of the time was spent playing volleyball

Multiply this together

8*3/4 = 8/4*3 = 2*3 = 6 hours

5.  We have 4 lbs of wings.  We divide it into 1/8 lbs parts

4 ÷ 1/8

Copy dot flip

4 * 8/1

32 portions
