Answer:

x 2 + 5 x + 6

Step-by-step explanation:

y = m x + c

y- intercept

x = 0

y = (-2) (0) + 3

(x =0, y = 3)

<h3>slope -2 </h3><h3>y = -1 x + 3</h3>

14) The ratio of green to red gummy bears in a package is 3:7. If there are a total of 80

yulyashka [42]

Answer:

There are 56 red gummy bears

Step-by-step explanation:

The ratio of green to red gummy bears is = 3 : 7

Total gummy bears = 80

We need to find how many gummy bears are red?

We can write it as:

3x : 7x

where x is the common ratio.

We can write:

Quantity of Green gummy bears = 3x

Quantity of Red gummy bears = 7x

Total Gummy bears = 80

So, 3x+7x = 80

10x = 80

x = 8

Now, finding quantity of Red gummy bears by putting x = 8

7x = 7(8) = 56

So, There are 56 red gummy bears

A regular tube of toothpaste costs $2.50 for 3.2 ounces. A travel size tube costs $1.00 for 1.2 ounces. Compare the prices and w

Elanso [62]

Answer:

The regular size is more economical.

Step-by-step explanation:

Consider the provided information.

A regular tube of toothpaste costs $2.50 for 3.2 ounces.

Find out the unit rate as shown below:

$\frac{\$2.50}{3.2}=\$0.78$

Therefore, the cost of one ounce is $0.78.

A travel size tube costs $1.00 for 1.2 ounces.

Find out the unit rate as shown below:

$\frac{\$1}{1.2}=\$0.833$

Therefore, the cost of one ounce is $0.833.

From the above calculation we can observe that regular tube toothpaste price is better buy.

Now find the percent as shown:

Firs find the difference

$0.83-$0.78 = $0.05

Therefore,

$\frac{0.05}{0.78}\times 100\approx 6.41$

Hence, regular tube is 6.41% less costly as compare to travel size.
