Step-by-step explanation:

Billys mistake was when he multiplied the 80 by 12 instead of carrying the 1 from getting 160 from 80 x 2 he just put 16 and added 8 to it from 1 x 8.

Answer:

the graph does not represent a function

Answer:

[tex]\huge\boxed{\sf v = 80\ mph}[/tex]

Step-by-step explanation:

Given Data:

Distance = S = 100 miles

Time = t = 1 1/4 hours = 1.25 hours

Required:

Speed = v = ? mph

Formula:

v = S/t

Solution:

v = 100 / 1.25

v = 80 mph

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!

Answer:

8

As shown, the key to the table is 1Ibs = $2.00

4($2)

= 8

Answer:

6 (sorry if im wrong ): )

Step-by-step explanation:

If we are assuming that we are using the ratio 1:2, then you would multiply it by 4. This would make the ratio 4:8. Next, minus 2 from 8 = 6.

Answer: 8/15

Step-by-step explanation:

2/3 divided by 5/4:

To make the answer to 2/3 divided by 5/4 in decimal form, you simply divide the numerator by the denominator from the fraction answer:

8/15 = 0.5333

Answer:

8/15

Step-by-step explanation:

2/3 / 5/4 = 8/15

Answer:

4 2/21

Step-by-step explanation:

2/3 and 3/7 have a common denominator, 21

so, 14/21 and 9/21

plug in the whole numbers: 1 14/21 and 2 9/21

which will give you: 3 23/21

so, simplify it which will give u the answer: 4 2/21

Answer:

the answer is B

Step-by-step explanation:

hope this helps you!

Answer:

B

Step-by-step explanation:

You see that the question mentions MPH. An hour is 60 minutes, so you would look at the 60 minutes on the base of the graph. If you go directly up to where the diagonal (dark) line perfectly crosses a point of the grid (that's any corner of any square on this grid) and look directly to the left (which represents the MPH) you see the number 3. If you go even higher, you see 6 MPH.

The 3 miles at 60 minutes represents 3 MPH, which is Tanisha's speed.

The 6 miles at 60 represents 6 MPH, which must be Albert's speed.

Since 6 is two times bigger than 3, the correct answer is B) Albert is running two times faster than Tanisha is walking.

Answer:

Answer:

7 to the power of 7 ( which is 823,543 )

Step-by-step explanation:

Why? well if 4+3 is 7 the exponent would be 7 to because if you look carefuly it says with an exponent of 2 + 5 and 2 + 5 is 7 so your exponent is 7.

I hope This is right!

Answer:

-5 , 8 , 48 , -6

Step-by-step explanation:

-7- -2 = -5

This complies with the rule that 2 negatives make a positive.

12 + (-4) = 8

You just ignore the brackets.

-8(-6) = 48

The -8 next to the bracket with no symbol means you need to multiply, and again 2 negatives make a positive.

18/-3 = -6

As the 18 is not negative, but -3 is, the answer is also a negative because one negative and one positive make a negative!

Hope this helps and have a good day!

Answer:

27. My fiend solved the inequality correctly but graphed it incorrectly. The statement "x > 5" is correct but but since the symbol is "greater than" it should have been graphed with an open circle to the right rather than a closed circle to the right.

28. My friend is incorrect for both solving the inequality and graphing. The correct answer for solving the inequality would be "5 ≥ x ". And for graphing the correct answer would be closed circle to the right since the symbol is greater than.

Step-by-step explanation:

27. Solving the inequality

x - 7 > -2

+ 7 + 7

------- ------

0 5

answer: x > 5

Graphing the inequality

Since the symbol is greater than, it would be a open circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 28 the symbol is just greater than, not greater than or equal to.

28. Solving the inequality

8 ≥ x + 3

-3 - 3

-------- --------

5 0

answer: 5 ≥ x

Graphing the inequality

Since the symbol is greater than than or equal to, it would be a closed circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 27 the symbol is just greater than or equal to, not just greater than.

This might not be the right way to do it or the right answer for that matter, I am very new to solving and graphing inequalities so I just decided to give this one a shot.

Hope this helps ; )

Answer:

A

Step-by-step explanation:

==================================================

Explanation:

The customer saves 15%, but still pays the remaining 85%. The two percentages add to 100%.

85% of $900 = 0.85*900 = 765

After the 15% discount is applied, the customer would pay $765

---------

Then after the sale, the price is marked up by 15%

This means we'll multiply by 1.15 to indicate a 15% increase

1.15*765 = 879.75

Notice that we don't get back to the original price (900) even though we increased by the same percentage as before. This is because 15% of a smaller number is a smaller amount; ie we have a smaller increase compared to the decrease earlier.

---------

Afterwards, divide the value 879.75 over the original price of $900

879.75/900 = 0.9775

Move the decimal point two spots to the right to end up with 97.75%

That percentage rounds to 98% when rounding to the nearest whole percent.

Answer: C , combine like terms

Step-by-step explanation:

Answer:

The final Price is: $75.14

Step-by-step explanation:

you first have to do -=- which means /105=35%/100

then you would do 105x35=3675/100=36.75

then Subtract 105-36.75=68.25.

The next step is to do -=- /68.25=10.1%/100

you would multiply 68.25 and 10.1 and get 689.325 the you would divided that by 100 and get 6.89325 then you would add 68.25 and 6.89325 and get 75.14.

Step-by-step explanation:

Backpack 2 is 2x, 2y, so double each number:

(0,2) = (0, 4)

(8,2) = (16, 4)

(6,5) = (12, 10)

(2,5) = (4, 10)

(0,2) = (0,4)

Backpack 3 is x + 8, y - 2 so add 8 to x and subtract 2 from y:

(0,2) = (8, 0)

(8,2) = (16, 0)

(6,5) = (14, 3)

(2,5) = (10, 3)

(0,2) = (8, 0)

Backpack 4 is x, 2y, so keep the same x and multiply y * 2

(0,2) = (0, 4)

(8,2) = (8, 4)

(6,5) = (6, 10)

(2,5) = (2, 10)

(0,2) = (0,4)

Answer: 9:00 PM

Step-by-step explanation:

every 24 hours it will 4:00 PM again - so we do . . .  245 ÷ 24 = 10 days and 5 hours.  

so in 245 hours it will be 9PM
