Answer:

-3

Step-by-step explanation:

Let x equal the mystery number

Our equation will be:

x - 5 = 1 + 3x

Subtract x from both sides

-5 = 1 + 2x

Subtract 1 from both sides

-6  = 2x

Divide both sides by 2

-3 = x

To prepare for the school fundraiser, juanita pays $5 for 100 cups. She also buys Fruit juice for $.50 each. Write an equation t
ANTONII [103]

Answer:

f(x) = 0.5x + 5

Domain: positive whole numbers

Range: f(x) ≥ 5

Step-by-step explanation:

Let's x denote the total number of fruit juice.

This means that if $0.5 for each fruit juice, then the total cost incurred for fruit juice would be $0.5x.

Since she incurred a cost of $5 for 100 cups and $0.5 for each fruit juice, then the total cost, f(x), would be:

f(x) = 0.5x + 5

The domain would be all positive whole numbers (it is restricted to positive whole numbers because a fruit juice can't be "negative" neither can it be "half").

The range is all numbers equal or greater than 5. This is because, even if she does not eventually get fruit juice, she will still incur a cost of 5usd for cups.

A company has two manufacturing plants with daily production levels of 5x+14 items and 3x−7 ​items, respectively. The first plan
Anastasy [175]

Answer:

3x+24 more widgets

Step-by-step explanation:

A company owns two manufacturing plants:

1st plant: 8x+17 widgets;2nd plant: 5x-7 widgets.

To find how many more items the first plant produces daily than the second plant, we have to subtract from the number of widgets the first plant produces the second plant produces. So,

(8x+17)-(5x-7)\\ \\=8x+17-5x+7\ [\text{Eliminate brackets}]\\ \\=(8x-5x)+(17+7)\ [\text{Combine the like terms}]\\ \\=3x+24

hope this helps!

Data: (12 ,8 , 6 , 12 , 16 , 12 ) median ............. mode......
Vesna [10]
Ascending order=  6, 8, 12, 12, 12, 16

No of observations (n) = 6
Median = Mean of the values of (n/2) and (n/2+1)
             = Mean values of 3rd and 4th values
             = 12+12/2
             = 12
Therefore, median = 12

Mode = Most number of observations= 12
