Find the value of m .
35/50 = m/10
m = ___.

Answers

Answer 1
Answer:

(35)/(50)=(m)/(10)   Multiple 10 on both sides to get m by itself

(10)(35)/(50)=(m)/(10)(10)

(350)/(50)=m  Simplify

7 = m
Answer 2
Answer:

First, cross multiply

35 * m = 50 * 10

35m = 500

Then, Divide both sides by 35

m = 500 / 35

m = 14(2)/(7) or 14.29

James started tutoring children several times a week. The first 2 weeks he had to buy tutoring supplies and had losses of $40 and $56. The next three weeks he made a profit of $105, $70, and $140. At the end of the 6 weeks, he had a net profit of $252.

(a) write an equation to find the profit or loss for the 6th week in this situation. Solve your equation. Was there a profit or a loss for that week? Show your work.
(b) What was James's average profit or loss for the 6 weeks? Show your work.

Given:
Week 1 : - 40
Week 2 : - 56
Week 3 : 105
Week 4 :   70
Week 5 : 140
Week 6 : ?

At the end of the 6th week, net profit is 252.

Profit = 105 + 70 + 140 = 315
Loss = 40 + 56 = 96
Net Profit = 315 - 96 = 219
252 - 219 = 33 Profit on Week 6.

Average profit : 252 / 6 = 42 per week

Again Due Tomorrow!!Is (3,6) A Solution To
y = 3x - 3
and
y = 2x + 2

Answers

Plug in the values. The x value is 3, and the y value is 6. Act on that. The equation y = 3x - 3 changes to 6 = 3(3) - 3. Do those numbers work? Solve it.
6 = 3(3) - 3 --> 6 = 9 - 3 --> 6 = 6 ... So yes, (3, 6) is a solution for y = 3x - 3.
Now let's move on to the next equation. If we plug in the same x and y values, then y = 2x + 2 will change to 6 = 2(3) + 2. Now comes the solving ...
6 = 2(3) + 2 --> 6 = 6 + 2 --> 6 > 8 ... So the coordinates do not work for the second equation since the two answers are not equal.
y=x+3\n-2x+y=1\n\n-2\cdot3+6=1\n-6+6=1\n0=1\leftarrow \text{false}

Which system of equations can be used to solve the following problem?Each child ticket for a ride costs $3, while each adult ticket costs $5. If the ride collected a total of $115, and 33 tickets were sold, how many of each type of ticket were sold? Let c be the number of child tickets and a be the number of adult tickets.


A.3c+5a=33
a + c=115


B. 3a+5c=33
a + c=115

C. 5c+3a=115
c + a=33

D. 3c+5a=115
a +c

Answers

the answer is C. 5c+3a=115
c + a=33
if each child's ticket is $3 and there are 4 child tickets sold, then the total is 3×4if each child ticket is $3 and there are "c" child tickets sold, the total is 3c for the childs tickets

The area of a plot of land is 2496 square meters. A small part of the land is fenced. The ratio of the area of the plot of land to the area that is not fenced is 48:31. What is the area of the land that is not fenced?

Answers

My late response (haha): First, you would write a proportion.

Step 1: 2496 over 48 = x over 31
(x represents the area of the land that is not fenced).

Step 2: Cross multiply
2496 times 31 and x times 48

Step 3: Calculate
77376 = 48x

Step 4: Divide both sides by 48
77376/48 = 1612
48x/48 = x

Step 5: Write it as a sentence 
The area of the land that is not fenced is 1612 squared meters. 

Hope that helped! Good luck! :]
