Randi and her sister make balloon animals and sold them for $.50 each. They made $48.00. If rando made twice as many animals as
nydimaria [60]

Randy made 64 ballon animals and her sister made 32 ballon animals

<em><u>Solution:</u></em>

Let the number of ballon animals sold by Randi be "x"

Let the number of ballon animals sold by her sister be "y"

Cost of 1 ballon animal = $ 0.50

<em><u>Rando made twice as many animals as her sister</u></em>

Number of ballon animals sold by Randi = twice the number of ballon animals sold by her sister

x = 2y ---- eqn 1

<em><u>Together, they earned $ 48</u></em>

Therefore, we can frame a equation as:

Number of ballon animals sold by Randi x Cost of 1 ballon animal + number of ballon animals sold by her sister x Cost of 1 ballon animal = 48

2y \times 0.50 + y \times 0.50 = 48

1y + 0.5y = 48\\\\1.5y = 48\\\\y = \frac{48}{1.5}\\\\y = 32

<em><u>Therefore, from eqn 1</u></em>

x = 2y

x = 2(32)

x = 64

Thus Randy made 64 ballon animals and her sister made 32 ballon animals

2x + 3y = -6<br> -2x + 3y = 6<br><br> How do I graph it
Elanso [62]

Answer:

(-3, 0)

Step-by-step explanation:

\:  \:  \: 2x + 3y =  - 6 \\ -2x + 3y =  \:  \:  \: 6   \\   \frac{ +  \:  \:  \:  \:  \:  \:  -   \:  \:  \:  \:  \:  \: =  - }{ }{}  \\  \:  \:  \:   4x \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  - 12 \\ \\  x =  \frac{ - 12}{4}  \\  \\ x =  - 3

now,

-2( - 3) + 3y = 6 \\  6 + 3y = 6 \\ 3y = 6 - 6 \\ 3y = 0 \\ y =  \frac{0}{ 3}  \\ y = 0

thus, (-3, 0)
