LMNO is a parallelogram
so NM = OL
x + 15 = 3x + 5
solve for x
x - 3x = 5 - 15
-2x = -10
x = 5

Answer
x = 5

Since LMNO is a parallelogram all the sides are equal so if you take 3x+5 and x+15 youll find that if you replace x with 5 on each side youll end up with 20 total on both sides therefore your answer is x equals 5.

Find two supplementary angels such that the measure of the first angle is 38° less than three times the measure of the second

stiks02 [169]

angle 1+ angle 2=180 supplementary angles add up to 180

angle 2=x assign angle a variable

angle 1= 3x-38 find equation for first angle

3x+x-38=180 set both angles added together equal to 180

4x-38=180 combine like terms

4x=218 add 38 to both sides

x=54.5 divide by 4

angle 2= 54.5

angle 2= (3x54.5)-38 plug back in and solve

angle 1= 125.5

A farmer grows two types of grain in his fields. He has a seed budget of $17,000.00 and has spent $9,200.00 to plant wheat seed

Helen [10]

Okay so first you have to subtract 17000 from 9200 to see how much money you have left to spend. Then once you get that number, which is 7800, you have to see what's that maximum number of acres that you can get. So you divide 7800 from 41.00 and you can get your answer. Your answer will be 190 acres. 190 acres is the highest you can go without going over budget.

Solve the system of equations by graphing on your own paper. What is the x-coordinate of the solution?

Dovator [93]

Y = x + 7
y = -2x - 11

x + 7 = -2x - 11
3x + 7 = -11
3x = -18
x = -6

The x-coordinate of the solution is -6.

I have attached a graph of the two equations since the question really wanted you to graph it and then find the answer.
