ANSWER IF YOU KNOW

Allison drew a number line to model seven eighths − two eighths. Is the model correct? Explain why or why not. You can write out the fraction names or use the forward slash (/) on your keyboard to represent the fraction bars.

A number line from zero to one partitioned into eighths. There are five hops beginning at seven eighths and ending at two eighths.

Answers

Answer 1

did it show the number line she threw?

Answer 2

Answer:

no, because the number line shows the arrow going backward, so now we know its subtraction, so you're going to count backward until you reach the number we are looking for so 7/8 minus 2/8 equals 5/8.

I need 3 paragrahps Please read the promtp !

Answers

Before we write 3 paragraphs, we need to solve the equation ourselves using the order of operations.

Order of Operations: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. (PEMDAS)

3 · (10 - 2) + 4²

3 · (8) + 4²

3 · (8) + 16

24 + 16

40

Finally, here's the prompt:

The requirements of the prompt are to show step-by-step how to solve the problem and to explain the order of operations in 3 paragraphs.

 In order to solve the equation, we have to understand the order of operations, which is the order used in solving expressions. The order of operations are parenthesis, exponents, multiplication, division, adding, and finally subtracting. It's usually abbreviated to 'PEMDAS'.

 The first step of solving the equation is solving what's in the parenthesis, which is 10 - 2. By subtracting, you should get 8. The second step is solving the exponents, which is 4 to the second power. to do that, we multiply 4 by itself, so we should get 16. Now, for the third step, we have to multiply 3 x 8 before we add 16 so we follow the order of operations. After multiplying 8 x 3, you should get 24.

 Now, all that's left is to add 24 and 16. Our answer should be 40. That's how you solve the equation using order of operations. In this equation, we only used parenthesis, exponents, multiplication, and addition. Even though there was no division or subtracting (besides subtracting in parenthesis), we still follow the order of operations.

Answer: I did Parenthesis, I subtracted 10-2, that gave me 8. Next I did exponents, I multiplied 4 twice or to the 2nd power. That gave me 16. Then I multiplied 3 and 8 and that equals 24. After that the only thing left to do is add 16 and 24 which equals to 40. That's how I got my answer by using PEMDAS. I followed the order of operations even though I didn't have to use division.

Write the following as ordered pairs.

y = 6x
4x + y = 7

y = 3x
x = -2y + 70

Answers

Y=3x ≈ 3(10)
X= -2(3x) + 70
X= -6x + 70

7x=70
Divide both sides by 7
X=10
Y=30

Jason plans to join a health club. The club charges $6.50 per week plus a $20 enrollment fee. If Jason has budgeted to spend no more than $250 this year on health club expenses, how many weeks will he be able to workout at the club?

A. 20w + 6.5 ≥ 250

B. 20 + 6.5w ≥ 250

C. 20w + 6.5 ≤ 250

D. 20 + 6.5w ≤ 250

Answers

take 250$ - 20$ = 230$
then 230$ divide by 6.50$ per week

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?

Answers

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.

Georgia practiced for her dance recital for 3/4 of an hour on Monday, 3/8 of an hour on Tuesday, and 5/6 of an hour on Wednesday. How much longer did she practice on Monday than on Tuesday?

Answers

Answer:

The Answer is 22.5

Step-by-step explanation:

because 3/4 is 45 minutes.'

and 3/8 is 22.5 minutes.

45-22.5=22.5 minutes different.

ANSWER:
3/8 longer or 2 times longer or 22.5 minutes longer on Monday depending on the type of answer they want.

EXPLANATION:
3/8 longer or 2 times longer Explanation is:
Gotta find common denominator
Common denominator is 8
6/8 on Monday and 3/8 on Tuesday so difference of 3/8 or twice as long

22.5 Minutes Longer explanation is:
3/4 of an hour is 45 minutes (60/4=15x3=45) 3/8 of an hour is 7.5 minutes (60/8=7.5x3=22.5)
So 45-22.5= 22.5 minutes longer on Monday

Trevor is having trouble understanding how the degree of a nonzero constant is 0. Use the expression 3x^0 to help explain this concept to Trevor.

A. The degree of a monomial is the sum of the number of its variables. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Therefore, the degree of the nonzero constant 3 is 0.
B. The degree of a monomial is the coefficient of its variable. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Since the expression has no variables, the degree of the nonzero constant 3 is 0.
C. The degree of a monomial is always zero. Therefore, the degree of the nonzero constant 3 is 0.
D. The degree of a monomial is the sum of the exponents of its variables. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Therefore, the degree of the nonzero constant 3 is 0.

Answer:

1) 2 boots for 7 shoes = 8 boots for 7x4 shoes (28 shoes)

2) 7 shoes for 2 boots = 49 shoes for 2x7 boots (14 boots)

Answer:

1. 28

2. 14

Step-by-step explanation:

1. As you can see on the bottom 2x4=8 (or 8 divided by 2) so all they did was multilpy the first number by four so to get the second number on the top you have to do the same thing (7x4=28)

2. Now that you have the second number on the top you can find the third number on the bottom. So all you have to do is divide 49 by 28 which is 1.75, then you would go down to the bottom and do 8 times 1.75 and you get 14

the boeing 747 airplane is 250 feet in length. If a model of this airplane is 8 inches long, what scale was used to create the model.

please help!!!

Answers

answer: The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first:  19/38, since 19 is the size of the model's length and 38 is the real length.  For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:

19*x = 38*18

19x = 684

36m because 250 divided by 8=36m
