What is the solution to this equation?
1/2x-7=1/3(x-12)
x=

Answers

Answer 1

Answer:

[tex]x=18[/tex]

Step-by-step explanation:

By rearranging and multiplying by 6 at the end:

[tex]\frac{1}{2}x - 7 = \frac{1}{3}(x-12)\\\frac{1}{2}-7 = \frac{1}{3}x - 4\\\frac{1}{2}x - \frac{1}{3}x = -4 + 7\\(\frac{3}{6} - \frac{2}{6})x = 3\\\frac{1}{6}x = 3\\x = 3 \cdot 6 = 18[/tex]

I took the test

which equation represents the line that has a slope of 4 and passes through the point (2, 7)?
(A) y = 4x - 1
(B) y = 4x + 15
y=x+4
D y =
= 2x-4

Answers

Answer:

A) y = 4x - 1

Step-by-step explanation:

y = mx + b

y = 4x + b

7 = 4(2) + b

7 = 8 + b

-1 = b

y = 4x - 1

0.8 = 0.5x

Solve for x

Please show steps thanks so much

Answers

If I’m not mistaken, to solve for x you have to get it by itself so you need to divide 0.5 from both sides:

0.8/ 0.5 = 0.5x/ 0.5

Cross out the 0.5’s on the right because they cancel out and you will end up with:

0.8/ 0.5 = x

All you have to do then is divide 0.8 by 0.5 and you get:

1.6 = x

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [

Answers

Answer:

y = 4x+3

Step-by-step explanation:

The equation in point slope form is expressed as y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

If a line is parallel to y = 4x + 1, the slope of the line m = 4

Substitute m = 4 and the point (-2, -5) into the equation above;

y - (-5) = 4(x - (-2))

y+5 = 4(x+2)

y+5 = 4x+8

y = 4x+8-5

y = 4x + 3

Hence the equation of the line is y = 4x+3

25 apples to 10 oranges. What is the rate of the fruit

Answers

Answer:

The rate of the fruit is 5 apples to 2 oranges.

Step-by-step explanation:

The rate of the fruit is the ratio of apples to oranges. That is, the number of apples divided by the number of oranges into its simplest fraction form:

[tex]x = \frac{25\,apples}{10\,oranges}[/tex]

[tex]x = \frac{5\,apples}{2\,oranges}[/tex]

The rate of the fruit is 5 apples to 2 oranges.

You would have to step up your problem like this 2x-3=-x+3, then you add -x to both sides. So, the problem will look like this 3x-3=3 then add to both sides. The ending problem will look like this 3x=6 then divide 3 to both sides then your answer is 2! Hopefully this is correct!

Graph the line with a slope of 2/3 that contains the point (−3,−5)

Answers

Answer:

Step-by-step explanation:

So for the given information, it would be easiest to use slope-intercept form, which is y=mx + b, where m is the slope and b is the y-intercept.

We can plug in 2/3 for the slope, because we are given that.

y=2/3x + b.

To find the y-intercept, plug in the given point for x and y and solve for b.

-5 = 2/3 · (-3) + b

-5 = -2 + b

b = -3

So now we have the complete equation of the line.

y = 2/3x -3

Now to graphing.

We can put the y-intercept, (0, -3), and the given point, (-3, -5) on a graph.
