Answer:
m= -20/7
Step-by-step explanation:
5m+72=−2m+52
Add 2m to each side: 7m + 72 = 52
Subtract 72 from each side: 7m = -20
Divide each side by 7: -20/7

Jill can run 20 miles in
three hours at a steady
rate. How many minutes
will it take her to run
five miles?
Answer:
45 minutes
Step-by-step explanation:
Change 3 hours to minutes
1 hours = 60 minutes
3 hours = 180 minutes
Using proportions
20 miles 5 miles
------------- = ----------------
180 minutes x minutes
Using cross products
20x = 5* 180
20x =900
Divide each side by 20
20x/20x = 900/20
x =45
45 minutes
Answer: 45 minutes
Step-by-step explanation: 20 miles in 180 minutes, 5 miles is 1/4 of 20 miles so you divide 180 by 4 which gives you 45

Mr. Anderson has 4/5 of a pizza left over and split it among his 4 children. What fraction of the pizza did each child get? * 11 points 1/5 2/3 16/5 16/20
Answer:
The answer is 1/5
Step-by-step explanation: Turn 4 in to a fraction (4/1) and take 4/5 then flip the the 4/1 fraction (1/4) and multiply it by 4/5. 4/5*1/4=4/20 simplify it 1/5. Hope this helped!

The sum of 2 numbers is 25. The sum of their reciprocals os 1/4. Determine the two numbers.
Answer:
5, and 20
Step-by-step explanation:
5+20=25
reciprocal of 5 is 1/5 and reciprocal of 20 is 1/20 so 1/5=4/20 and 4/20 + 1/20 = 5/20. 5/20 = 1/4

<1 and <2 form a linear pair. The measure of <2 is six more than twice the measure of <1. Find the measure of <2
Answer:
122 Degrees
Step-by-step explanation:
Since we are given that angle 1 and 2 make a linear pair:
angle 1 + angle 2 = 180 degrees ----------------------------(1)
We have also been told that angle 2 is 6 more than twice the measure of angle 1
Which means: angle 2 = (2*angle1) + 6 -------------------(2)
From putting the value of angle 2 in (1) from (2)
angle 1 + 2*angle 1 + 6 = 180
3*angle 1 = 174
angle 1 = 58 degrees -----------------------(3)
From (1) and (3):
angle 2 + 58 = 180
angle 2 = 122 degrees
Therefore, the measure of angle 2 is 122 degrees

A number is doubled and then increased by nine. The result is ninety- Three. What is the original number?
Answer:
42
Step-by-step explanation:
First you subtract 93 by 9. You get 84. Then you divide it by 2. Which is your answer, 42.
This can be represented as:
93=2x+9
First subtract 9 from both sides
84=2x
Then divide by 2 on both sides
42=x

Write the equation of line in slope-intercept form.
Line parallel to y=−2x+3 that passes through the point (−100,−100)
Answer: y= -2x - 500
Step-by-step explanation:
Parallel lines have the same slopes but different y-intercepts. This means that the line parallel to y=-2x + 3 will have the same slope which is -2.
We will input the x and y coordinates for the given point into the formula and solve for the y-intercept to write the equation.
-100 = -2(-100) + b where b is the y-intercept
-100 = 400 + b
-400 -400
b = -500
The y intercept is -500 and the slope is -2 therefore, the equation will be
y= -2x - 500

When do you use the divergence test, comparison test, p test, geometric, integral, comparison, limit comparison, and alternating series?
Step-by-step explanation:
Divergence Test: use this when the limit as n approaches infinity of a sequence isn't 0.
If lim(n→∞) an ≠ 0, then an diverges.
(Note this only tests divergence, not convergence.)
P Test: use this when the series is a p-series.
For an = 1 / nᵖ, if p > 1, then the series converges. Otherwise, it diverges.
Geometric Test: use this when the series is a geometric series.
For an = a₁ (r)ⁿ, if -1 < r < 1, then the series converges. Otherwise, it diverges.
Integral Test: use this when the sequence can be easily integrated.
If ∫₁°° f(x) dx converges, then ∑₁°° f(n) converges.
If ∫₁°° f(x) dx diverges, then ∑₁°° f(n) diverges.
Comparison Test: use this when a sequence is similar to a p-series or a geometric series.
If bn > an and bn converges, then an converges.
If bn < an and bn diverges, then an diverges.
Otherwise, inconclusive.
Limit Comparison Test: use this when comparison test is inconclusive.
If an ≥ 0 and bn > 0, and lim(n→∞) an/bn > 0 and finite, then an and bn either both converge or both diverge.
Alternating Series Test: use this when the series is alternating. This usually includes (-1)ⁿ or (-1)ⁿ⁺¹, but might use trig functions instead.
If an = (-1)ⁿ bn or (-1)ⁿ⁺¹ bn, where bn ≥ 0, and if lim(n→∞) bn = 0, and bn is decreasing, then an converges.
(Notice this only tests for convergence, not divergence.)
Bao can eat 12 chicken wings in 3 minutes. She eats the chicken wings at a constant rate.
How many chicken wings can Bao eat in 12 minutes?
chicken wings
Stuck?
Answer:
48
Step-by-step explanation:
If Bao eats 12 chicken wings in 3 minutes than that will help us find the unit rate by dividing 12 by 3, and then you will get 4. Now that you know the unit rate you will multiply it by 12 and get 48.
Answer:
For this we have to do simple division and multiplication, giving us the answer of 48.
Step-by-step explanation:
The easiest way to solve this is to first divide 12 by 3, giving us 4, the amount of time it would take for Bao to eat a single chicken nugget. And then since the question asks how many Bao can eat in 12 minutes, you would multiply 4 by 12, thus giving you the answer of 48.

Is 4x + 9 equivalent to 2(2x+5) -1?
Answer: Yes!
Step-by-step explanation:
1. So you have: 4x+9 and 2(2x+5)-1
2. Simplify the 2nd expression: 2(2x+5) -1 = 4x + 10 - 1 = 4x+9
4x+9 = 4x+9
Answer:
Yes
Step-by-step explanation:
Set them equal to each other to see. If they are, then you should come out with the answer 0 = 0.
4x + 9 = 2(2x + 5) - 1
4x + 9 = 4x + 10 - 1
