The instructions on the bag on concrete mix say to add 2 gallons of water to each 8 pounds bag of conceit mix
tiny-mole [99]

Answer:

4 pound

Step-by-step explanation:

From the question :

2 gallons of water = 8 pound bag

Number of pound bag per gallon of water ;

Let the number of pound = x

Using cross multiplication, we'll have :

2 gallons = 8 pounds

1 gallon = x pounds

Cross multiply

2x = 8

x = 8 /2

x = 4

Hence, 1 gallon of water mixes 4 pound bag of concrete.

I=0.13x+1025 A textbook salesperson's monthly income depends on the amount of his sales. His monthly income is a salary of $1025
Snezhnost [94]

Answer:

l = 0.13x+1025

Step-by-step explanation:

Let the monthly sales be x

Monthly income = $1025 + 13% of monthly sales

Monthly income = $1025 + 0.13x

Since l  represent the monthly income

l = 1025+0.13x

Rearrange

l = 0.13x + 1025

Hence the linear equation representing the statement is l = 0.13x+1025

Suppose the total area is represented by the equation x^2+14x+24. If the area 1 is x^2 square units and area IV is 24 units, wha
Nutka1998 [239]

Answer:

See Explanation

Step-by-step explanation:

Given

Total = x^2 + 14x + 24

Area\ I = x^2

Area\ IV = 24

Required

True about area II and III

The question is incomplete; so, I will answer using general knowledge.

If the total area is:

Total = x^2 + 14x + 24

And there are 4 areas, then;

Total = Area\ I + Area\ II + Area\ III + Area\ IV

Rewrite as:

Total = Area\ I + Area\ IV+ Area\ II + Area\ III

This gives:

x^2 + 14x + 24 = x^2 + 24+ Area\ II + Area\ III

Collect like terms

x^2 -x^2 + 14x + 24 -24=  Area\ II + Area\ III

14x =  Area\ II + Area\ III

Rewrite as:

Area\ II + Area\ III  = 14x

<em>So, the sum of areas III and IV must be 14x</em>
