The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

We have the slope m = -2 and y-intercept (0, 3) → b = 3. Substitute:

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

Solution:

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

Rando made twice as many animals as her sister

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

x = 2y ---- eqn 1

Together, they earned $ 48

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

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

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

Therefore, from eqn 1

x = 2y

x = 2(32)

x = 64

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

The product of three consecutive numbers is 21,924. What is the smallest number out these numbers?

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

Let the middle number be x.

(x - 1)(x)(x + 1) = 21,924

You can solve that equation, or you can use logic.

The 3 numbers are going to be close to the cubic root of 21,924.

cubic root of 21,924 = 27.988 or approx 28.

Try 27, 28, 29

27 * 28 * 29 = 21,924

Answer: 27
