8/9=4/5k how to solve

Mathematics

velikii [3]3 years ago

Divide both sides by 4/5 or multiply by the reciprocal.

Flip 4/5 to get the reciprocal.
The reciprocal of 4/5 is 5/4 so we will multiply both sides by that.

5/4 * 8/9 = 4/5 * 5/4 * k

4/5 and 5/4 cancel out so now you have


5/4 * 8/9 = k

multiply top and bottom
(5 *8 )/(4*9)

40/36

Simplify

Answer:

The coordinates of N are (-1,-6)

Step-by-step explanation:

M is the midpoint of AN

A(-7,4) and M(-4,-1)

The distance AM is given by (-4--7,-1 - 4) = (3,-5)

Since AM = MN;

N = M(-4,-1) + (3,-5)

N = (-4 + 3,-1 + -5)

This gives the coordinates of N to be;

N(-1,-6)

<u>Corrected Question</u>

Matt makes $80 a month mowing lawns. His friend James also mows lawns, but he makes x dollars less per  month than Matt does. James makes a total of $816 per year. How much less each month does James make than Matt? Solve the linear equation to find the value for x

. Remember that x represents how much less per month James makes than Matt

Equation: 12(80 – x) = 816

Answer:

x=$12

Step-by-step explanation:

To solve the given equation

12(80 – x) = 816

First, we distribute:

960-12x=816

Collect like terms

12x=960-816

12x=144

Divide both sides by 12

x=12

Therefore, James makes $12 less than Matt every Month.
