Larry and Steve have 171 marbles in all.  The number of marbles Larry has is 39 fewer than 3/7 of the number of marbles Steve has.  How many marbles does Steve have?

Answers

Answer 1
Answer: Steve = x marbles,    Larry = 3x/7 – 39 marbles
Total marbles = 171 = steves + lary’s
X + 3x/7 – 39 = 171
X + 3x/7 = 171 + 39
10x/7 = 210
10x = 210 * 7
10x = 1470 X = 147
 Larry = 3/7(147) – 39  
Larry = 63 – 39 = 24
Steve = 147
 Total marbles = 147 + 24 = 171

To solve, find out how many times more miles that Rhonda rode for; this is a multiplication problem.
Rhonda rode for 10.2 miles.
The correct equation for this problem is r-1.8=8.4. Solve the problem by adding 1.8 to both sides.

Answers

Answer:

Option B and D is correct.

Step-by-step explanation:

we are given with the following:

Distance Steve biked = 8.4 miles

Distance Rhonda biked = r

According to the Question,

Steve bikes 1.8 miles less than Rhonda biked.

So,   r - 8.4 = 1.8

or     r - 1.8 = 8.4

add 1.8 on both side

r - 1.8 + 1.8 = 8.4 + 1.8

r = 10.2 miles

Therefore, Option B and D is correct .i.e., To solve, find the difference that Steve and Rhonda biked; this is a subtraction problem.  and Rhonda rode for 10.2 miles.  The correct equation for this problem is r-1.8=8.4. Solve the problem by adding 1.8 to both sides.

Tim mows neighborhood lawns for extra money. Suppose that he would be willing to mow one lawn for ​$12​, a second lawn for ​$15​, and a third lawn for ​$23. Also suppose that three neighbors are interested in having their lawns mowed. Mrs. Jones would be willing to pay ​$30 to have her lawn​ mowed, Mr. Wilson would be willing to pay ​$26​, and Ms. Smith would be willing to pay ​$23. Considering Mrs.​ Jones, Mr.​ Wilson, and Ms. Smith​ together, what will be their consumer​ surplus?  ​

Answers

$29 will be their consumer surplus.

Consumer surplus is the difference between how much a consumer is willing to pay and how much a consumer actually does pay.

$12.00 + $15.00 + $23.00 = $50.00 (How much the consumer actually pays)

$23.00 + $26.00 + $30.00 = $79.00 (How much the consumer is willing to pay)

$79.00 - $50.00 = $29.00 (Consumer surplus)
