The problem is the image (How is everyone day)

Answer:

casey has the faster rate

Step-by-step explanation:

first multiply jessicas race distance and time by 2

30 * 2

= 60

5 * 2

= 10

we did that so both jessicas time and caseys time was the same, making it easier to solve ( also by this point we already know who has the faster rate )

now we are going to divide both of their times and distances by 5

casey

10/5

= 2

45/5

= 9

jessica

10/5

= 2

60/5

the step is to divide their times/distances once again but this time by 2

casey

2/1

= 1

9/2

= 4.5

jessica

2/1

= 1

12/2

= 6

and our answer is 4.5 or casey !

4.5 > 6

hope this helps you! :)

The inequality is not true

Step-by-step explanation:

we have

$-2(2x+9)> -4x+9$

Correct Answers only please! I only have two attempts on this assignment, and I cannot retake it. I've already tried the answer

Answer: A. x= 5"

Step-by-step explanation:

ORIGINAL/NEW = 11"/7" = 8.5"/x

x = 7" x 8.5"/11" = 59.5"/11 = 5.409 ≅ 5.41"

If we wanted to keep most of the engraving, we would adjust the larger dimension, but we have been asked to adjust one dimension to 5", since it is said that C. x = 5.41 is incorrect

Then we will adjust the minor dimension to 5"

ORIGINAL/NEW = 11"/y = 8.5"/5"

y= 11" x 5"/8.5" = 6.47"

Then new dimensions of the paper are 6.47" x 5" to fit an 7" x 5" frame

Answer: A. x= 5"

How do u find the unit rate? <br> Pls explain it with 18 miles in 3 hours <br> thx

Tomtit [17]

Let's turn this into a fraction using the given information we already have.

$\frac{18}{3} \frac{miles}{hour}$

We want the denominator, or the bottom part of the fraction, to be 1 in order for us to have a unit rate.

This fraction can be simplified if we divide both the numerator and denominator by 3.

Numerator: 18/3 = 6

Denominator: 3/3 = 1

Now we have

$\frac{6}{1} \frac{miles}{hour}$

Any number divided by 1 is equal to that number.

$6 \frac{miles}{hour}$

Thus, your unit rate is 6 miles per hour.

Have an awesome day! :)
