Jackie needs to save $125 to go to a concert. He has saved $35. He makes $7.50 an hour at his job.

Let x representing the number of hours.

Which equation and solution can be used to show how many hours jackie must work in order to have enough money to go to the concert?

A. 125x + 35 = 750; x = 5.75
B. 35 - 7.5x = 125; x = 6
C. 7.5x + 35 = 125; x = 12
D. 35x + 125 = 750; x = 18

Answers

Answer 1

Answer:

C

Step-by-step

Answer 2

Answer:

Answer is C

Step-by-step explanation:

First Jackie needs to save $125

y = 125

He already saved $35, this is our constant

He makes $7.50 an hour on his job,

Our variable x is hours

125 = 7.50x + 35

If we solve for x, we get x = 12

What is -9 ÷ 2/3?
I got: -27/3
Is it right?

Answers

No, the answer should be -27/2

Answer:

1.35

Step-by-step explanation:

Unfortunately you are wrong, the correct way to evaluate this problem…

We know 2/3 is 6.6 repeating

So if we do 9 divided by 6.6

We would get 1.35

Also I don’t know how your teacher want you to evaluate, but -27/3 can become a mixed number (9) which is obviously incorrect because 9 divided by a decimal lower that 1 is going to be a decimal lower than one.

Theresa's Book Barn sold $10,347 worth of books during September. In October, their sales were $12,115. How much higher were Theresa's book sales during October than in September? Explain how you got your answer.

Answers

Answer:

$1,768

Step-by-step explanation:

We know that Theresa's Book Barn sold $10347 worth of books in September, and $12,115 in October. Since we want to know how much higher the sales were in October than in September, we would have to subtract.

So, we would have to subtract the two numbers.

  12,115
- 10,347
    1768

Subtracting the two numbers gives us $1,768, which is the difference.

Answers

Answer:

Step-by-step explanation: The equivalent expression will be (-2)/ (-13) and-(-2/13) so option (A) and option (B) both will be correct. In such a fraction, the value that appears above the horizontal line is referred to as the numerator. It represents the number of pieces removed from the whole.

The denominator of a fraction is the numerical value that comes before the brings together various.

If we divide two numbers by each other than the upper word is called the numerator, and a lower word is called the denominator. For example, a fraction 1/5 here 1 will be the numerator and 5 will be denominated.

Given that now since the multiplication of - and - quantity is always positive so - and - is positive so it will be 2/13

If you take both options A and B in both options, the negative sign is going to be canceled and it will give a positive value.

Hence "The equivalent expression will be (-2)/ (-13) and-(-2/13)".

Answer is -1.25

Step-by-step explanation:'

You start by making sure everything in the problem is a decimal which means turning 1 1/4 into 1.25 and then adding the two numbers together -2.5+.25=-2.25

-2.25+1=-1.25

Brainliest would be nice.

Answer:  -3.125  or  -25/8

Step-by-step explanation:

I do not know what has been covered in your class, but the "x" appears to be multiplication here.

It would be best to convert into all decimals or all fractions.

For all fractions (I think is easiest):

-2.5  is -2  1/2 = -5/2   and then 1  1/4  = 5/4  (need improper fractions to multiply, then multiply straight across)

Then take -5/2  *  5/4  = -25/8    (multiply fractions by multiplying numerators together, then denominators together).  If you need this as a mixed number, -25/8  is    -3  1/8

For all decimals:

-2.5 is already as a decimal,  then 1  1/4  = 1.25

So then multiply:

1.25     (I put 1.25 first because it has more digits)

x -2.5   (note- multiplying a positive by a negative gives you a negative)

   

 6  2 5     (multiply 5x5 first, giving 25, so place 5 and carry the 2,

                  then multply 5x2 = 10 plus the 2 carried is 12, carry that 1

                 then 5x1 = 5  plus the 1 carried is 6)

+  2  5 0 0   (0 placeholder first, now multiply the 2 by each digit of 1.25,  

                   2x5 = 10, carry the 1, then multiply 2x2 = 4  plus the 1 carried

                     is 5,  then multiply the -2 by the 1 ,  -2x1 = -2)

 Now add the 625 + 2500 = 3125, there were 3 digits after the decimal originally, so move decimal back 3 places, giving 3.125.  Finally, the answer is negative because you multiplied a negative number with a positive one.  SO the final answer is -3.125   (also equal to the -25/8)

Factor the numerator of the given expression.

Rewrite 64 as 4³ and 1 as 1³:

[tex]\textsf{Apply the exponent rule} \quad a^b \cdot c^b=(ac)^b:[/tex]

[tex]\implies (4x)^3-1^3=(4x-1)\left(16x^2+4x+1\right)[/tex]

Step 2

Replace the numerator in the given expression with the factored numerator from step 1:

[tex]\implies \dfrac{64x^3-1}{4x-1}=\dfrac{(4x-1)\left(16x^2+4x+1\right)}{4x-1}[/tex]

Cancel the common factor (4x - 1):

Harry made a scale drawing of the elementary school. The schoolyard, which is 154 meters long in real life, is 22 millimeters long in the drawing. What scale did Harry use?
1 millimeter : __ meters

I'm sorry that there is no picture or drawing

Answers

Answer:

Based on the information given, the scale

that's used by Harry for drawing the schoolyard will be 1:7000.

Firstly, it should be noted that

meter = 1000 milliliters

Therefore, 154 meters = 154,000

millimeters

Since the schoolyard is 154 meters long in real life but is 22 millimeters long in the

drawing, then the scale will be:

= 22/154000

= 1/7000

a. 20 − (4 ⋅ 3)
b. (20 − 4) ⋅ 3
c. 20 + 4 − 3
d. 20 ⋅ 4 − 3

Answers

Answer:

a. 20 - (4 ⋅ 3)

Step-by-step explanation:

PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Please note that multiplication 4 ⋅ 3 will happen before the subtraction -

If we add parentheses, we introduce a new "order". But if the parentheses are around the first operation we perform, the order stays the same!

This means that answer a. must be correct.

We verify:

20 − 4 ⋅ 3 = 20 - 12 = 8

a. 20 − (4 ⋅ 3) = 20 - 12 = 8

b. (20 − 4) ⋅ 3 = 16 ⋅ 3 = 48

c. 20 + 4 − 3 = 21

d. 20 ⋅ 4 − 3 = 80 - 3 = 77

Answer: A: 20 - (4 x 3)

Step-by-step explanation:

In the end, the final answer is 8, so we need to see which one of these options give us 8. As seen, we first must solve the multiplication, and the first option, A, solves the multiplication first because it is in parenthesis, which gives us 8, so the correct answer is A.

First, solve what's in the parentheses remembering that when two exponents have the same base and are being multiplied together, their exponents add together:

3 + (-1) = 2

(2^2) / 2^2

And when two exponents with the same base are being divided by each other, the exponents subtract:

2 - 2 = 0
