Hello!

To convert \frac{3}{4} to a fraction with a denominator of 8, multiply the fraction by \frac{2}{2}; \frac{2}{2} =1, so the fraction is equivalent, but would have an increased numerator and denominator.

\frac{3}{4} * \frac{2}{2} = \frac{6}{8}

Your new fraction is \frac{6}{8}. Add it to \frac{5}{8}:

\frac{6}{8} + \frac{5}{8} = \frac{11}{8}

Now we must convert it to a mixed number. To do that, divide 11 by 8.

Answer:
1 \frac{3}{8}

3/4= x/8
3 is to 4 as x is to 8
cross multiply
(3*8)= (4*x)
24= 4x
divide both sides by 4
6= x

3/4= 6/8

Or 4 goes into 8 two times. Multiply 3 by two, which equals 6

Add 6/8 to 5/8:
6/8 + 5/8
=11/8
=1 3/8 mixed number

ANSWER: 6/8 and 1 3/8

Hope this helps! :)

Consider this expression.
schepotkina [342]

Answer:

9m^2 + 17m- 9

Step-by-step explanation:

Given

7m^2 + (2m - 1)(m + 9)

Required:

Simplify

We start by opening the bracket

7m^2 + (2m(m + 9) - 1(m + 9))

7m^2 + 2m^2 + 18m - m - 9

Collect Like Terms

9m^2 + 17m- 9

Hence, the equivalent expression is 9m^2 + 17m- 9

I need help on listing the four points that have a distance of 8 from B, thank you!
dolphi86 [110]

Answers:

  • (12, 3)
  • (-4, 3)
  • (4, 11)
  • (4, -5)

A diagram is shown below.

===========================================================

Explanation:

First we locate point B at (4,3). The '4' in the x position means we've gone 4 units to the right of the origin, and the 3 in the y coordinate means we've gone 3 units up.

Now we need to find four points that are 8 units away from this central location. We'll ignore point A.

What we can do is add 8 to the x coordinate of point B to get x+8 = 4+8 = 12. Keeping the y coordinate the same, the point (12, 3) is exactly 8 units away from (4,3). Think of drawing a number line through those two points. Then we can note there are 8 spaces between (4,3) and (12,3). Or we can say "there are 8 spaces between 4 and 12" since that '3' doesn't really play much of a role in this case.

So (12,3) is one answer.

---------------------------------

Move back to point B(4,3)

Instead of adding 8 to the x coordinate, let's subtract 8 from it

x-8 = 4-8 = -4

Again the y coordinate is kept the same.

The point (-4, 3) is 8 units away from (4,3). The number line distance from -4 to 4 is 8 units.

So (-4,3) is another answer.

----------------------------------

Move back to point B

From this starting point, we can move 8 units up. Doing this means we add 8 to the y coordinate, while the x coordinate is kept intact.

(4,3) turns into (4,11) after doing so.

(4,11) is another answer.

---------------------------------

Move back to point B

From this point, we can move down 8 units to arrive at (4,-5). note how y-8 = 3-8 = -5. The x coordinate is kept the same.

(4,-5) is another answer.

----------------------------------

The four points we found were:

  • (12, 3)
  • (-4, 3)
  • (4, 11)
  • (4, -5)

which are four possible answers

Those points are found by going 8 units right, 8 units left, 8 units up and 8 units down in that order. Each time we started at point B as our center of operation. The use of the word "center" is done because we can form a circle of radius 8, and the center of the circle is at B(4,3). Any point on the circle's edge is exactly 8 units away from the center point B.

Refer to the diagram below. The four answers are the red points P,Q,R,S. The point T is another point that could be an answer, but it's not as easy to find compared to the four other points.
