Answers

We have that for the Question "The cost of a gallon of orange juice is 3.50. What is the maximum number of can trainers you can buy for $15?" it can be said that the maximum number of can trainers you can buy for $15 is

x=4.285

From the question we are told

The cost of a gallon of orange juice is 3.50. What is the maximum number of can trainers you can buy for $15?

Generally the equation for the maximum number is mathematically given as

$x=(amount you have)/(price)\n\nx=(15)/(3.50)$

x=4.285

Solve the following equation. Then determine if the equation is an identity or a contradiction.2(3n + 3) - 9 = 6n

Answers

Let's solve the equation step by step:

1. Start with the equation: $2(3n+3)-9=6n$.

2. First, distribute the 2 on the left side of the equation:
$6n + 6 - 9 = 6n$.

3. Next, simplify the equation by combining like terms. The 6n on both sides can be canceled out:
$6 - 9 = 0$.

4. Simplify further:
$-3 = 0$.

Now, let's analyze the result:

The equation $-3 = 0$ is a contradiction. This means that there is no value of $n$ that will satisfy the equation. In other words, there is no solution to this equation.

The area of a rectangle is 21 m squared, and the length of the rectangle is 1 m less than twice the width. Find the dimensions of the rectangle. Help?

Answers

This should be right because I checked it afterwards
Width=W
Length=2W-1
The equation is as follows
W(2W-1)=21
$2W^(2)$ -W=21
Subtract 21 from each side
$2W^(2)$ -W-21
Group them/put them in parentheses..can't think of the right word right now
(2W-7)(W+3)
-7=I7I
You only do this for the first parenthese, 7÷2W=3.5
W=3.5
If W=3.5 then 2W-1⇒2×3.5-1⇒7-1⇒6
Length=6
If W=3.5 and L=6, then W(2W-1)=21
3.5(2×3.5-1)=21
Solve in parentheses first
3.5(7-1)=21
3.5(6)=21
3.5×6=21
The width is 3.5
The length is 6
