<h3><u>The first number is equal to 10.</u></h3><h3><u>The second number is equal to 8.</u></h3>

x = 2 + y

2x = 3y - 4

Because we have a value of x, we can plug it into the second equation to solve for y.

2(2 + y) = 3y - 4

4 + 2y = 3y - 4

Subtract 2y from both sides.

4 = y - 4

Add 4 to both sides.

8 = y

We can plug this into the original equation to solve for x.

x = 2 + 8

x = 10

Nathan needs some paint for his bedroom. He finds two cans of white paint, four cans of green paint and three cans of pink paint
horsena [70]

The probability of randomly selecting a can of pink paint is P = 1/3, so the correct option is A.

<h3>What is the chance that he will paint his bedroom pink?</h3>

Assuming that all the cans of paint have the same probability of being randomly selected, the probability that he will choose a pink can is equal to the quotient between the number of pink cans and the total number of cans.

There are 2 cans of white, 4 cans of green, and 3 cans of pink, so a total of 9 cans.

Then the probability is:

P = 3/9 = 1/3.

The correct option is A.

Compound inequality that represents all the numbers between -4 and 6
KatRina [158]
You can write it as:
-4≥x≤6

*The '≥' and '≤' just means that it is greater than or less than but it can still be equal to the number you are comparing it to.

Hope this helps! :)

Application 11. Dasha took out a loan of $500 in oeder to buy the # 1 selling book in the world, "Math, What is it Good For?" by
finlep [7]

Answer:

\boxed{\text{\$581.25; \$81.25}}

Step-by-step explanation:

The formula for the total accrued amount is

A = P(1 + rt)

Data:

P = $500

r = 6.5 % = 0.065

t = 30 mo

Calculations:

(a) Convert months to years

t = 30 mo × (1 yr/12 mo) = 2.5 yr

(b) Calculate the accrued amount

A = 500(1 + 0.065 × 2.5)

  = 500(1 + 0.1625)

  = 500 × 1.1625

  = 581.25

\text{Dasha will have to pay back }\boxed{\textbf{\$581.25}}

(c) Calculate the accumulated interest

\begin{array}{rcl}A & = & P + I\\581.25 & = & 500 + I\\I & = & 81.25\\\end{array}\\\text{The accumulated interest is }\boxed{\textbf{\$81.25}}
