Ms. Albero decided to make juice to serve along with the pizza at the Student Government party. The directions said to mix 2 scoops of powdered drink mix with a half gallon of water to make each pitcher of juice. One of Ms. Albero’s students said she will mix 8 scoops with 2 gallons of water to make 4 pitchers. How can you use the concept of proportional relationships to decide whether the student is correct?
Step-by-step explanation:
2scoop: .5 gal= ONE PITCHER
1scoop: .25gal= HALF PITCHER
×8
8scoop: SHOULD BE 2gal= 4 PITCHERS
Answer: The student is correct.
Step-by-step explanation:
Consider the provided information.
The directions said to mix 2 scoops of powdered drink mix with a half gallon of water to make each pitcher of juice.
This can be written as:
2 scoops = 1/2 gallons of water
Multiply both side by 2
2×2 scoops = 2×1/2 gallons of water
4 scoops = 1 gallons of water
That means Ms. Albero wants 4 scoops for each gallons of water.
Albero’s students said she will mix 8 scoops with 2 gallons of water to make 4 pitchers.
This can be written as:
8 scoops = 2 gallons of water
Divide both side by 2.
8/2 scoops = 2/2 gallons of water
4 scoops = 1 gallons of water
That means Albero’s students used 4 scoops for each gallons of water, which is the same quantity of scoops per gallons as suggested by the Ms. Albero.
So the student is correct.

How many solutions does the equation 4x + 2(x − 5) = 3(2x − 4) have? Group of answer choices infinitely many solutions exactly one solution no solution at least two solutions
Answer:
Step-by-step explanation:
4x + 2x - 10 = 6x - 12
6x - 10 = 6x - 12
-10 ≠ -12
no solutions
The number of solution will be;
⇒ No solution.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 4x + 2 (x - 5) = 3 (2x - 4)
Now,
Since, The expression is,
⇒ 4x + 2 (x - 5) = 3 (2x - 4)
Solve for x as;
⇒ 4x + 2x - 10 = 6x - 12
⇒ 6x - 10 = 6x - 12
⇒ - 10 = - 12
⇒ - 10 ≠ - 12
Thus, It has No solution.

Mark bought 18 pounds of apples for $6. Use the ratio table to find the cost of 3 pounds of apples.
Answer:
$1
Step-by-step explanation:
To set this ratio up, you would put $6 over 18lbs is equal to x over 3lbs.
Next, multiply $6 and 3lbs to give you 18.
Finally, divide 18 by 18 to give you a final answer of $1. Hope this helps!

Jade wants to verify that the expression 5(3x – 6) is equivalent to 15x – 30. She substitutes 2 into each expression and evaluates each one. How will she know if 5(3x – 6) is equivalent to 15x – 30?
They are equivalent if the two values are the same.
They are equivalent if the value for 5(3x + 6) is greater.
They are equivalent if the value for 15x + 30 is greater.
They are equivalent if one value is negative and the other value is positive.
Answer:
They are equivalent if the two values are the same.

Solve for x in simplest form 1=1/3 (10x−3)
Answer:
x = 3/5
Step-by-step explanation:
1=1/3 (10x−3)
Multiply each side by 3
3=3*1/3 (10x−3)
3= (10x−3)
Add 3 to each side
3+3= (10x−3+3)
6 = 10x
Divide each side by 10
6/10 = 10x/10
3/5 =x
i need help showing my answer -7/12 + 1/2
Answer -1/12
Step-by-step explanation:
-7/12 + 1/2 cannot be added until you change 1/2 into 6/12.
To change 1/2 to 6/12, you have to multiply 1/2 by 6 because you want the same denominator. Since you can't just make a whole new fraction by changing the denominator, you have to multiply the numerator by 6 as well.
After changing the fraction, you should get -7/12 + 6/12.
now you can just add the numerators and denominators together and get -1/12!

Any number to the power of zero is always?
Answer:
