\mathfrak{5x + 15 = 28}

\mathfrak{5x = 28-15}

\mathfrak{5x = 13}

\boxed{\mathfrak{x = \dfrac{13}{5}}} → option B.

Answer:

B

Step-by-step explanation:

The first thing you need to do is,

28 - 15

which is 13.

Now look at the answer choices and multiply them by 5.

It cannot be C or D because it would not fit the equation.

If anyone of them equal 13 then it is the answer.

Now lets try it.

43/5 = 8.6

13/5 = 2.6

8.6 times 5 is way to big so A is not it.

2.6 times 5 is 13.

So it is B.

How many solutions do you think the equation -10x+3=5x-27 has? Explain. Then, find the solution(s).
deff fn [24]
This will only have one solution because it does not deal with a quadratic. Then to isolate x you need to get the similar terms on different sides by subtracting or adding, Then divide both sides by the number next to x (coefficient).

Solve the following system of linear equations by graphing.
Oksanka [162]

Answer:

See Explanation

Step-by-step explanation:

For y=-\frac{1}{2}+3: (0,3) (2,2)

The equation is in slope intercept form. y=mx+b

The y intercept is 3.

The slope is 1/2.

Moving one unit down and 2 units to the right, we get (2,2)

For y=2x-2: (0,-2) (1,0)

The y intercept is -2.

The slope is 2.

Moving 2 units up and 1 unit to the right, we get (1,0)
