Answers

Answer 1
Answer: Isolate m using inverse operations, get m by itself. (addition and subtraction, mult. and div.)

7m-35=5+2m\ (subtract\ 2m) \n 5m-35=5\ (add\ 35) \n 5m = 40\ (divide\ by\ 40) \n \boxed{m=8}
Answer 2
Answer: First add 35 to both sides. Second subtract 2m from both sides. Lastly divide both sides by 5.

Your school wants to collect at least 5,000 box tops for a fundraiser. Write and graph an inequality to describe the amount of box tops that your school hopes to collect.

Answers

The answer is: b\geq5,000 and the graph is attached.

The explanation is shown below:

1. You must use the information given in the problem to write the inequality.

2. b represents the number of  box tops for the fundraiser. Based on the information, the value of b must be greater than or equal to 5,000 box tops. Therefore, you have that the inequality is:

b\geq5,000

3. Then, you obtain the graph attached. As you can see, you must use a closed circle for ≥.

Jenny has saved $3,800 over the last 12 months. She saved either $250 or $350 a month. During the 12 month period, how many times did Jenny save $250 for the month?

Answers

Answer:

Jenny save 4 times \$ 250 for the month

Step-by-step explanation:

Given Jenny has saved \$3,800 over the last 12 months.

She saved either \$250 or \$350 a month.

Let the number of months to save \$250 be x

Let the number of months to save \$350 be y

Total period is 12 month.

x+y=12 \ \ \ \ equation\ 1

Jenny has saved $3,800 over the last 12 months.

250x+350y=3800

Dividing both side from 50 we get,

(250)/(50)x+(350)/(50)y= (3800)/(50)

5x+7y=76 \ \ \ \ equation\ 2

Now Multiplying  equation 1 by 5 we get,

5*(x+y)=5* 12\n5x+5y=60\ \ \ \ equation \ 3

Now Subtracting Equation 3 by equation 2 we get,

(5x+7y=76)-(5x+5y=60)\n2y=16\ny=(16)/(2)= 8

Substituting the value of y in equation 1 we get,

x+y=12\nx+8=12\nx=12-8\nx=4

∴ Jenny save 4 Months of  \$ 250 and 8 Months of  \$ 350in a 12 month duration

Answer:

4 times

Step-by-step explanation:

Let,

250 = x

350 = y

x + y = 12

250x + 350y = 3,800

Solve the system.

x = 4 and y = 8

Therefore, Jenny saved $250 for 4 months and $350 for 8 months.

What is 132654 rounded to the nearest hundred thousand

Answers

When rounding, always look to the number directly to the right of the number in the place that must be rounded. If the number is 5 or exceeds 5, change the number in the place that must be rounded to one higher number. If nothing exceeds, keep the number as is and change all other preceding places to 0.

In this case, your hundred thousand place would not change because the 3 next to it does not exceed 5.

Therefore, it will be 100,000

Hope this helps :)
