130 apples at the party. There were 3 times as many yellow apples as green apples, there were twice as many red apples as yellow

kipiarov [429]

Answer: There were 78 red apples at the party.

Step-by-step explanation:

This situation can be represented by the equation

x + 3x + 2(3x) = 130 where x is the number of green apples, 3x is the number of yellow apples and 2(3x) is the number of red apples.

Now solve for x

x +3x +2(3x) =130

4x + 6x = 130

10x = 130

x = 13

Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.

2 * (3*13) = ?

2 * 39 = 78

Which expressions are equivalent to Negative 9 (two-thirds x + 1)? Check all that apply.

Sav [38]

Answer:

$-9(\frac{2}{3}x) + 9(1)\\ \\-6x + 9$

Explanation:

Before we begin, remember the following rules:

1- Distribution property:

$a(b+c) = ab+ac$

2- Simplification of fractions:

$\frac{xy}{yz}=\frac{x}{z}$

3- Signs in multiplication:

+ve * +ve = +ve

-ve * -ve = +ve

+ve * -ve = -ve

Now, for the given problem, we have:

$9 (\frac{2}{3}x + 1)$

Starting with the distributive property:

$-9 (\frac{2}{3}x +1) = -9(\frac{2}{3}x) - (-9)(1) = -9(\frac{2}{3}x) + 9(1)$

..................>This corresponds to option 1

Now, we simplify the output from the above step:

$-9(\frac{2}{3}x) + 9 = \frac{-9*2}{3}x + 9 = -6x+9$

................> This corresponds to option 5

Hope this helps :)

coldgirl [10]

25 divided by 5 is 5 so she gave 5 stamps each week
64 divide by 3 would roughly be 12 weeks because otherwise it would be a renainder
12 add 5 equals 17 weeks
So it should take 17 weeks
hope this is right Please ask me if any doubts
Thank you Good Luck
