Alaina is selling wreaths and poinsettias for her chorus fundraiser. Wreaths cost $27 each poinsettia cost $20 each. If she sold
marishachu [46]

Answer:

The number of wreaths Alaina sells is 9 .

Step-by-step explanation:

As given

Alaina is selling wreaths and poinsettias for her chorus fundraiser.

Wreaths cost $27 each poinsettia cost $20 each.

If she sold 15 poinsettias and made $543.

Let us assume that the number of wreaths Alaina sells = x

As the number of poinsettias  Alaina sells = 15

Than the equation becomes

27x + 15 × 20 = 543

27x + 300 = 543

27x  = 543 - 300

27x  = 243

x = \frac{243}{27}

x = 9

Therefore the number of wreaths Alaina sells is 9 .

Solve the system algebraically. y = 3 -1/2 x 3x + 4y = 1 What is the value of x?
4vir4ik [10]

Answer: x=-11

Step-by-step explanation:

You can use the Method of substitution.

Substitute the equation y=3-\frac{1}{2}x into the equation 3x + 4y = 1 and then you must solve for the variable x:

3x + 4y = 1\\\\3x + 4(3-\frac{1}{2}x) = 1\\

Apply Distributive property:

3x + 12-\frac{4}{2}x = 1\\3x+12-2x=1

Subtract 12 from both sides of the equation and then add the like terms. Then you get:

3x+12-2x-12=1-12\\3x-2x=-11\\x=-11

hector and alex traded video games. alex gave hector one fourth of his video games in exchange for 6 video games. then he sold 3
oksian1 [2.3K]

Answer:

20 games

Step-by-step explanation:

Lets work backwards; *Adding what he gave away or lost*

-Alex started with 16 video games

-Add the games gave to his brother (+2)

-Add the games he sold (+3)

-The number is 3/4 of his games

-Subtract the games he traded with hector (-1/4)

Equation: 16+2+3-6= 3/4 X (variable) *You can choose other than X*

21-6 = 15

15 = 3/4

Take the reciprical of 3/4 which is 4/3 and multiply it by both sides

4/3 x 15 = 3/4 x 4/3

4/3 X 15 = 20!

ALEX STARTED WITH <em>20 GAMES!</em>

A grocer mixed 3 types of white, green and black tea in 3:5:7 ratio, respectively. How many kilograms of each are needed to make
mart [117]

Answer:

There are 6/5 white, 2 green, and 14/5 black

Step-by-step explanation:

Think of it like this.

First we add up everything.

3x+5x+7x = 6kg

15x=6

We find x and plug it in to the equation.

x=2/5

3*2/5=6/5  (6/5 is white)

5*2/5=2      (2 is green)

7*2/5=14/5   (14/5 is black)

There are 6/5 white, 2 green, and 14/5 black
