Answer:

#5. m<NMO = 44 and X = 9

Step-by-step explanation:

#5. 5x - 1 + 3x + 4 = 75 (<NMP is the entire angle, which equals 75.)

combine like terms

8x + 3 = 75

subtract 3 from both sides and divide 8.

x = 9

5(9) - 1

m<NMO = 44

Fred spent half of his allowance going to the movies. He washed the family car and earned 6 dollars. What is his weekly allowance if he ended with 16 dollars

Answers

Answer:

His weekly allowance is 20 dollars

Step-by-step explanation:

the full equation would be (with x equaling weekly allowance):

(x÷2)+6=16

subtract 6 from each side to get

(x÷2)=10

then multiply each side by 2

x=20

Weekly allowance is $10. He ended with $16, so subtract 6 from 16 to get 10. $10 was the amount he still has left, and since he spent half multiply 10 by 2 to get $20

Answer:

x=27

Step-by-step explanation:

Aight so the angle of line AB equals 180 degrees. You have 36 degrees plus the right angle (90 degrees) which gets you 126 degrees. Subtract 126 from 180 and you get 54, the remaining value. So if 2x=54, then divide both sides by 2 to get x=27. that should be it

Answer:

6.5 rounded from 6.53...

to see if this is correct we can:

13.5+9.5+6.5*3 = 42.5

but since we rounded it we can say its 6.5

Answer:

6.55 meters each day

Step-by-step explanation:

You know that in the end the fence must be 42.6 meters long.

On Monday & Tuesday, he installed 22.95 meters of fence. (We know this because 13.45 + 9.5 = 22.95).

So, how much is left? You find that by subtracting 22.95 from 42.6.

42.6-22.95 = 19.65 meters

There are 3 days left of fencing, and these days he will install equal lengths, so you can divide 19.65 meters by 3 days.

19.65 / 3 = 6.55 meters of fence per day

Find an equation of the straight line that is perpendicular to the straight line x+2y=5 and that passes through the point (3,7)

Answers

Answer: y = 2x + 1

Step-by-step explanation:  

Rewrite the equation in standard form:

x+2y=5

2y = -x + 5

y = -(1/2)x + (5/2)

A line perpendicular to this would have a slope that is the negative inverse of the reference line slope, -(1/2), here.  The new slope would be 2.  The y-intercept, (5/2), will change, so we'll just use b for the new y-intercept, and calculate it later:

y = 2x +b

We know that point (3,7) lies on the new line (it is a solution to the equation), so we can use this point to find the new y-intercept, b.

7 = 2*3 + b

b = 1

The perpendicular line is y = 2x + 1, and goes through point (3,7)
