What is the solution to the equation

Mathematics
1 answer:
Dimas [21]3 years ago
6 0

Answer:

D) 21!

Step-by-step explanation:

So what we are dealing with here is some fractions that need to be made equal

Think about the fractions 1/2 and 2/4. They look different, right?

Well really, they are equal to another. All we need to do is simplify them!

If we divide the numerator and denominator (the top and bottom) of the fraction by, lets say, 2!

2 / 2 = 1

-          -

4 / 2 = 2

And viola! It's been simplified down, and now we can see they are alike!

2 pieces of a pie cut in 4 pieces is the same as 1 piece of a pie cut in half!

(pro-tip, always try dividing a fraction by 2 first)

So now, using the same principal, we can solve this problem

By taking the denominators and dividing them like this:

35 / 5 = 7

We get 7! Now since we need to make these fractions equal, lets multiply the 7 we just got by the numerator of the second fraction, 3

7 x 3 = 21

So if we put the 21 over the 35, we get 21/35!

Thus, our answer is 21!

To find the surface area, you need to do the following:
A side of the figure is a trapezoid, so you should do 13+5x7 (since there are 2 of the same sides there is no need to divide by two.) and it should equal 126. To find the area of the top of the figure, you need to do 5x2 which equals 10. The area of the bottom of the figure is 26 (13x2), then do 2x3x2 to get the sides on the left and right of the figure. After all of this, add them together. (126+10+26+12=174.)
The surface area should be 174mm.

Find the perimeter of a triangle with sides 15 inches, 15 inches, and 21 inches length.
Degger [83]

find the perimeter of a triangle with sides 15 inches, 15 inches, and 21 inches length

To find the perimeter of a triangle we add all the sides of the triangle

The length of the sides of the triangle are given as 15 inches, 15 inches, and 21 inches

Perimeter of a triangle =

15 inches + 15 inches +   21 inches = 51 inches

So 51 inches is the perimeter

Identify an equation in slope intercept form for the line parallel to y= -2/3x+8 that passes through (4, -5)
Evgen [1.6K]

Answer:

3y = -2x -7

Step-by-step explanation:

The equation of the line;

     y = -\frac{2}{3}x + 8

Unknown:

Equation of the line passing through (4, -5);

Solution:

To solve this problem;

    the equation of a line is given as;

        y = mx + c

where x and y are the coordinate

           m is the slope

          c is the intercept

To solve this problem,

  The slope  -\frac{2}{3} if the same as that of the new line since they are parallel;

Equation of the new line;

    x  = 4 and y = -5

     -5 =  -\frac{2}{3} x 4 + c

      -5 = -\frac{8}{3} + c

       c  = -5 + \frac{8}{3}

       c = -\frac{7}{3}

So, the equation of the line is;

    y =  -\frac{2}{3}x - \frac{7}{3}

 or ;

     3y = -2x -7
