-3/4 x + 1/2 = 3/4 solve for x please

Mathematics
1 answer:
velikii [3]3 years ago
3 0

Answer:

x = -\frac{1}{3}

Step-by-step explanation:

  1. 1/2 = 2/4
  2. Plug 2/4 in: -3/4x + 2/4 = 3/4
  3. Subtract 2/4 from each side, so it now looks like this: -3/4x = 1/4
  4. Divide each side by -3/4, so it cancels out the -3/4 next to x. It should now look like this: x = -1/3

I hope this helps!

Find the sum of 5
vova2212 [387]

Answer:

\frac{10}{50} + \frac{35}{50}

Sum: [/tex] \frac{9}{10} [/tex]

Step-by-step explanation:

Given, \frac{1}{5} and \frac{7}{10}

Expressing in an equivalent form whereby they would have a common denominator, we would multiply the numerator and denominator of each fraction by the denominator of the other fraction.

Thus, we would have:

\frac{1 \times 10}{5 \times 10} = \frac{10}{50}

\frac{7 \times 5}{10 \times 5} = \frac{35}{50}

\frac{10}{50} + \frac{35}{50}

The sum is: \frac{10}{50} + \frac{35}{50} = \frac{10 + 35}{50} = \frac{45}{50}

Simplify

\frac{45}{50} = \frac{9}{10}

If the gradient of the line joining the points [4,-9]and [-3,h]is -3, find the value of H
Scrat [10]

Answer:

<h2>h = 12</h2>

Step-by-step explanation:

To find the value of h use the formula for finding the slope of a line

That's

m =  \frac{y2 - y1}{x2 - x1}

Where ( x1, y1) and (x2 ,y2) are the points

From the question

slope = - 3

The points are [4,-9] and [-3,h]

Substitute these values into the equation

We have

- 3 =  \frac{h + 9}{ - 3 - 4}

- 3 =  \frac{h + 9}{ - 7}

Cross multiply

That's

- 3(-7) = h + 9

21 = h + 9

h = 21 - 9

We have the final answer as

<h3>h = 12</h3>

Hope this helps you
