If 3m = 19 - n and 2m + 5n = 30, then what is the value of m?
Answers
Answer:
m=5
Step-by-step explanation:
We can solve this by using a system of equations. The easiest way to solve this is by using substitution.
3m=19-n Subtract both sides by 19 to find n.
-19 -19
3m-19=-n Divide everything by -1 to make n positive.
/-1 /-1
n=-3m+19
Now, we can substitute n into the second equation.
2m+5(-3m+19)=30 Substitute (-3m+19) into n.
2m-15m+95=30 Simplify.
-13m+95=30 Simplify and subtract both sides by 95.
-95 -95
-13m=-65 Divide both sides by -13.
/-13 /-13
m=5
We don't need to solve for n at all, so that is the answer!

Graham drove 42 1/3 miles in 1 1/3 hours. What is the unit rate for miles per hour? Use pencil and paper. Describe a situation in which the unit rate would be easier to work with than the given rate.
Answers
Answer:
Step-by-step explanation:
42+(1/3)
42*(3/3)+(1/3)
(126/3) + 1/3
126/3 + 1/3 = 127/3 miles
4/3 hours
(127/3)/4/3)
(127/3)*(3/4)
= 127/4 or 31.75 miles/hour
It would have been nicer if we were told Graham's distance after 1 hour (when he had travelled 31.75 miles).

Step-by-step explanation:
First, you substitute.
x + 6 / 4
26 + 6 / 4
Then, you add.

Answers:
x = 60y = 70============================================
Explanation:
The parallel lines show that x = 60 since the 60 and the x angles are alternate interior angles. Alternate interior angles are congruent when we have parallel lines like this.
Focusing on the largest triangle, the three angles add to 180 degrees
x+y+50 = 180
60+y+50 = 180
y+110 = 180
y = 180-110
y = 70
This triangle appears to be equilateral, but it's not entirely so (it's fairly close however). That 50 degree angle in the bottom right corner would need to be 60 degrees for it to be equilateral.
Give the x-intercept for the equation 6x + 3y = -9
Answers
Answer:
-9/6 or -3/2
Step-by-step explanation:
To find the x intercept, substitute y = 0 into the equation:
6x + 3(0) = -9
Now simplify,
6x + 0 = -9
6x = -9
x = -9/6 → -3/2
Tip: If you were finding the y-intercept, you would substitute x = 0 into the equation instead

A factory makes 84 toys robots in a day after they purchase new equipment now they make 205 robots a day
Answers
Based on the given information the percent gain is 144%.
Initial production rate = 84 toy robots per day
Present production rate = 205 robots per day
Using this formula
Percent gain= Increase in production rate /Initial production rate× 100
Where:
Increase in production rate = 205 - 84 =121
Initial production rate = 84 toy robots per day
Let plug in the formula
Percent gain=121/84×100
Percent gain=144%
Inconclusion the percent gain is 144%.
