A 4 foot steel pipe weighs 15 pounds. How much will a similar pipe weigh if it is 7 feet long?
Step-by-step explanation:
Let's take the unit ratio of weight to length:
[tex] \frac{15 \: pounds}{4 \: feet} = 3.75 \frac{pound}{feet}[/tex]
Now that we have the unit ratio, let's multiply it to the similar pipe which is 7 feet long.
[tex]3.75 \frac{pounds}{feet} \times 7 \: feet = 26.25 \: pounds[/tex]

2х - Зу = 9
5x - Зу = 30
Answer:
(x, y) = (7, 5/3)
Step-by-step explanation:
2x - 3y = 9
5x - 3y = 30
(5x-3y) - (2x-3y) = 30 - 9
5x-3y - 2x +3y = 21
3x = 21
x = 7
So, substituting the value of x into the first equation, we get 2*7 - 3y = 9. Simplifing, we get,
14 - 3y = 9
-3y = -5
y = 5/3

How many solutions exist for the given equation 12x + 1 = 3(4x + 1) -2
Answer:
All real numbers are solutions (hope that helps)
Step-by-step explanation:
12x+1=3(4x+1)−2
Step 1: Simplify both sides of the equation.
12x+1=3(4x+1)−2
12x+1=(3)(4x)+(3)(1)+−2(Distribute)
12x+1=12x+3+−2
12x+1=(12x)+(3+−2)(Combine Like Terms)
12x+1=12x+1
12x+1=12x+1
Step 2: Subtract 12x from both sides.
12x+1−12x=12x+1−12x
1=1
Step 3: Subtract 1 from both sides.
1−1=1−1
0=0

Anna is making a gallon of iced tea, which requires 6 cups of iced tea mix. She only has 1/4 - cup measuring cup. How many 1/4 scoops of iced tea mix does anna need?
Use words and numbers to explain your answer. What operation did you use to solve and why?
Answer:
24 scoops of iced tea
Step-by-step explanation:
Well, the way that I am going to solve this question is by calculating how many 1/4 cups she needs to get 1 cup and then multiply that by 6.
1/4 x 4 = 1
So 4 times 6 equals 24.
In conclusion, she needs 24 scoops
1/4 x 24 = 24/4. 24 divided by 4 equals the 6 cups Anna needs
