Answer:

1. 10d + 5n = 85

2.  idk how to attach stuff

3. 17 nickels  

4. 8.5 thats weird tho since its not possible to get 85 with using only dimes you would have to use 8 dimes and 1 nickel but its doesn't ask for that so 8.5 ig

Step-by-step explanation:

5n = 85

5*17 = 85

10d = 85

Answer:

3.14

Step-by-step explanation:

compare 3.4 to 3.111111111111111111...

4 is bigger than 1

3.14 is bigger than 3.1 repeating.

The number 3.1 repeating (or 3.1 with an infinite number of decimal places of 1) is equivalent to the mathematical concept of the number 3.1111..., where the digit 1 repeats indefinitely.

When comparing 3.14 and 3.1 repeating, we can consider the decimal places:

3.14 has a hundredth place digit of 4, which is greater than the repeating decimal of 3.1, where the hundredth place digit is 1.

Therefore, 3.14 is bigger than 3.1 repeating.

Answer:

x² + x + 5

Step-by-step explanation:

Using Synthetic division

 - 5 | 1    6    10     25

        ↓  - 5   - 5   - 25

       -----------------------

        1    1      5      0 ← remainder

Since the remainder is zero then (x + 5) is a factor of the polynomial

The Quotient = x² + x + 5

Thus

x³ + 6x² + 10x + 25 = (x + 5)(x² + x + 5)

32h (1 day and 8h )

Step-by-step explanation:

268-12=256

256:8= 32

32h

Answer:

8x+12= 268

Step-by-step explanation:

We know that Lester already has $12, so that would be: +12

Since he works for $8 an hour, x will represent each hour: 8x

*x will determine the number of hours, if you want days, then divide the amount of hours by 24.

Answer:

a = 38 degrees

Step-by-step explanation:

ok that line is equal to 180 degrees

180 of the line subtract 52 degrees and 90 degrees equal the missing angle

52 + 90 = 142

180 - 142 = 38

a = 38

Maxwell runs faster than Hayley

In order to determine who runs faster, the average speed has to be determined

Average speed is total distance travelled divided by total time travelled.

Average speed = Total distance / Total time

Hayley's average speed = [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{6}[/tex]

=  [tex]\frac{3}{4}[/tex] x 6 = [tex]\frac{9}{2} = 4\frac{1}{2}[/tex] miles / hour

Maxwell's average speed = [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{2}{15}[/tex]

[tex]\frac{2}{3}[/tex] x [tex]\frac{15}{2}[/tex] = 5 miles / hour

Maxwell runs faster because he has a higher average speed when compared with Hayley

For this question, you want to look at the equation and find a number with a variable.

For y = 2x + 3, 2x is the thing you should be looking at.

For the slope, you need to take out the x in 2x to find the answer. So, 2 should be your answer!

Answer:

Step-by-step explanation:

18+33=51

Answer:

Suppose that P(t) describes the position of Matt over time

Let's define the edge of the pool as our zero in the position axis.

At the beginning, Matt was 3 ft away from the edge, so we have:

P(0s) = 3ft

He walked away for 4 seconds, then he was 12 ft away from the edge.

Then at t = 4s his position was:

P(4s) = 12ft.

So we have two points, (0s, 3ft) and (4s, 12ft).

The graph that describes this situation will be the line that connects those two points.

An example is shown below.

Answer:

0,3 - 4,12

Step-by-step explanation:

Answer:

a) 1/3

b) 12/44

Step-by-step explanation:

To find the answer to a you must simplify the fraction 16/48 which would give you 1/3.

To find the answer to b you must first subtract 16 from 48 and then add 12. You should get 44 so your ratio of passengers who got on the bus at the stop compared to the new total then on the bus would be 12/44.

Answer:

Number of stickers Sarah had = 28

Number of stickers she put on her binder = x.

Number of stickers left with her = 28 - x

Number of stickers Haylee had = 40

Number of stickers she put on her locker = 3x

Number of stickers left with her = 40 - 3x

Both Sarah and Haylee had the same number of stickers left.

28 - x = 40 - 3x

=> 3x - x = 40 - 28

=> 2x = 12

=> x =  = 6

Answer:

100ft²

Step-by-step explanation:

The problem here is to find the area of the room that will give a length of 10ft.

  Note;

 The room is a square room.

Now let us solve this problem;

   Area of a square is:

    Area = L²

Where L is the length of the room;

So the area of the room is;

    Area = 10² = 100ft²

The area of the room that will give a length of 10ft is 100ft²
