5/6 n=10 show me how to solve it please

Answers

Answer 1
Answer:

Hey there! :)

Answer:

n = 12.

Step-by-step explanation:

Given:

5/6n = 10

Solve by isolating the variable. Divide both sides by 5/6. (Multiply by the reciprocal)

5/6n · 6/5 = 10 · 6/5

n = 10 · 6/5

n = 12.
Answer 2
Answer:

Answer:

6n = 10 ×5

6n = 50

n = 50/6

n = 8.3

Peter baked 64 loaves of bread in three days. How many loaves did he bake each day, if he baked 3 more loaves on the second day than on the first day, and 4 more loaves on the third day than on the first day?

Answers

Answer:

19

Step-by-step explanation:

1st day: x

2nd day: x+3

3rd day: x+4

Equation: x+(x+3)+(x+4)=64

                 3x+7=64

                   3x=57

                      x=19

I hope you found this answer helpful!!!!!!(sorry if instructions aren't clear)

A student is trying to solve the set of two equations given below:Equation A: x + z = 6
Equation B: 3x + 2z = 1

Which of the following is a possible step used in eliminating the z-term?
Multiply equation A by −2.
Multiply equation B by 2.
Multiply equation A by 3.
Multiply equation B by 3.

Answers

a possible step used in eliminating the z-term is "multiply equation A by −2."

x + z = 6
3x + 2z = 1

x + z = 6 / *(-2)
3x + 2z = 1


-2x - 2z = -12
3x+ 2z = 1

-2x + 3x -2z +2z = -12 +1
x = -11

-11 + z = 6
z = 6 + 11
z = 17

Answer:Multiply equation A by -2 is correct everyone

Find the slope of the line that passes through 6, 0 and −3, 2

Answers

Answer:

slope = - (2)/(9)

Step-by-step explanation:

calculate the slope m using the slope formula

m = \frac{y_(2)-y_(1) }{x_{2-x_(1) } }

let (x₁, y₁ ) = (6, 0 ) and (x₂, y₂ ) = (- 3, 2 )

substitute these values into the formula for m

m = (2-0)/(-3-6) = (2)/(-9) = - (2)/(9)

A man flies a small airplane from Fargo to Bismarck, North Dakota --- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only .9 hours. What is the plane's speed in still air, and how fast is the wind blowing?

Answers

Answer:

90 mi/h

Step-by-step explanation:

Calculate speed, distance, or time using the formula d = st, distance equals speed times time. The Speed Distance Time Calculator can solve for the unknown sdt value given two known values.

Time can be entered or solved for in units of seconds (s), minutes (min), hours (hr), or hours and minutes and seconds (hh:mm:ss).  

To solve for distance use the formula for distance d = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

Plane speed in still air: 120mph

Wind speed: 30pmh

Speed of plane to Bismarck: 90mph

Speed of plane to Fargo: 150mph

Many fundraisers ask for donations using e-mail and text messages. The paper "Now or Never! The Effect of Deadlines on Charitable Giving: Evidence From Two Natural Field Experiments" ( Journal of Behavioral and Experimental Economics [2016]: 1-10) describes an experiment to investigate whether the proportion of people who make a donation when asked for a donation by e-mail is different from the proportion of people who make a donation when asked for a donation in a text message. In this experiment, 1.32% of those who received and opened an e-mail request for a donation and 7.77% of those who received a text message asking for a donation actually made a donation. Assume that the people who received these requests were randomly assigned to one of the two groups (e-mail or text message) and suppose that the given percentages are based on sample sizes of 2000 (the actual sample sizes in the experiment were much larger). a. The study described is an experiment with two treatments. What are the two treatments? b. Use a 90% confidence interval to estimate the difference in the proportions who donate for the two different treatments c. Is there convincing evidence that the proportion who make a donation is not the same for the two different methods? Carry out a hypothesis test using a significance level of 0.05. d. Is there convincing evidence that the proportion who make a donation after receiving an email is smaller than the proportion who make a donation after receiving a text message? Carry out a hypothesis test using a significance level of 0.10.
