if the -8-13 are both in the denominator

-24/(-8-13)

-24/-21

divide both sides by -3

[-24/-3] / [-21/-3]

8 / 7

if the -13 comes after the division

(-24/-8) -13

insens350 [35]

For this case the distance will be given by:

d ^ 2 = (12 * 1.5) ^ 2 + (8 * 1.5) ^ 2

Rewriting we have:

d ^ 2 = (18) ^ 2 + (12) ^ 2

d ^ 2 = 324 + 144

d ^ 2 = 468

d = root (468)

d = 21.63 Km

Answer:

1) She did not find the full distance each traveled in 1.5 hours.

2) She should have used 12 km for Joseph's distance and 18 km for Isabelle's distance.

What is the value of minus 6 x cubed minus y squared minus 3 x y if if x = -2 and y = 4

Oksi-84 [34.3K]

Well, "minus 6 x cubed minus y squared minus 3 x y" translates to:

$-6x^{2} -y^{2} -3xy$

Then, if we insert the values for x and y, we get:

$-6(-2)^{2} -(4)^{2} -3(-2)(4)$

When we distribute and multiply:

$144-16-24$

And once we combine like terms:

1 point<br> Solve: 0.75 (x + 200) = 150.5 (2 – 28)<br> type your answer...

adelina 88 [10]

Answer:

$\huge \: x = - 5417.33$

Step-by-step explanation:

$0.75 (x + 200) = 150.5 (2 – 28) \\$

<u>Expand the terms and simplify</u>

That's

$0.75x + 150 = 301 - 4214 \\ 0.75x + 150 = - 3913$

Subtract 150 from both sides of the equation

$0.75x + 150 - 150 = - 3913 - 150 \\ 0.75x = - 4063$

<u>Divide both sides by 0.75</u>

$\frac{0.75x}{0.75} = - \frac{4063}{0.75} \\ x = - 5417.333333$

We have the final answer as

Hope this helps you
