Answer: 3 1/6 + 4 5/6 = 8 1/6.

Step-by-step explanation:

Let’s leave the whole numbers out for a second. You add 5/6 and 1/6 and that equals 1 or a whole. You add that to the whole numbers on the side of the fractions. So 3+4+1 =8. This is how the answer is 8 1/6.

Hope this helps :)

If the point (4,-2) is included in a direct variation relationship, which point also belongs in this direct variation? A. (-4,2)

IceJOKER [234]

Answer:

(-4,2) belongs in this direct variation.

Step-by-step explanation:

Let the direct variation relationship is expressed by the equation y = mx ........ (1), where x and y are in direct variation and k is the variation constant.

Now, the point (4,-2) is included in the direct variation relationship, then from equation (1) we get, -2 = 4m

⇒ $m = - \frac{1}{2}$

Therefore, the equation (1) becomes $y = - \frac{1}{2}x$

⇒ x + 2y = 0 ......... (2)

Now, from the given four options only the point (-4,2) satisfies the relation (2).

Hence, (-4,2) belongs in this direct variation. (Answer)

A person places $686 in an investment account earning an annual rate of 3.8%, compounded continuously. Using the formula V = Pe^

kykrilka [37]

Answer:

V = $1213.03

Step-by-step explanation:

We can determine the amount of money after 15 years with the given formula:

$V = Pe^{rt}$ (1)

Where:

V: is the value of the account in t years =?

P: is the principal initially invested = $686

r: is the rate of interest = 3.8% = 3.8/100 = 0.038

t: is the time = 15 years

By substituting the above values into equation (1) we have:

$V = Pe^{rt} = 686*e^{(0.038*15)} = 1213.03$

Therefore, the amount of money is $1213.03.

I hope it helps you!

2/3 (x - 7) = -2 what does x equal<br><br> (2/3 is a fraction not dividing)

ozzi

Answer:

x = 4

Step-by-step explanation:

Given

$\frac{2}{3}$ (x - 7) = - 2

Multiply both sides by 3 to clear the fraction

2(x - 7) = - 6 ← distribute left side

2x - 14 = - 6 ( add 14 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Nick has $50. He just got a job as a construction worker making $10 an hour. He wants to earn enough money to buy himself a new

Ilia_Sergeevich [38]

Answer:

900 $\geq$ 50+10x; At least 85 hours

Step-by-step explanation:

Nick must make at least 900 dollars, so the amount he has + earns must be greater than or equal to 900 in order to walk out of the store with it.

50 is the amount that Nick already has, and add that to 10x, which gives $10 for every x hour.

To solve, subtract 50 from each side.

850 $\geq$ 10x

Divide by 10 to solve for x:

85 $\geq$ x

Nick must work at least 85 hours.
