1/6x = 2/3 Multiply each sides by 6
x = [tex]\frac{2}{3}[/tex] x [tex]\frac{6}{1}[/tex]
x = 4
Answer:
Step-by-step explanation:
if they used 1 liter of sauce on each pizza, it would be 1x=2/3.
So if we use this for 1/6 of a liter of sauce on each pizza…
(x is the number of pizza’s they make.)
= [tex]\frac{1}{6}[/tex]х=[tex]\frac{2}{3}[/tex]
x6 on both sides
= 1x=9
Therefore, the pizza restruant made 9 pizzas.

5/11-1/10
Answer:
39/110 or 0.355
Step-by-step explanation:
subtract
5/11 - 1/10 = 5x10/11x10 - 1x11/10x11 = 50/110 - 11/110
50/110 - 11/110 = 50-11/110 = 39/110

$225 grows 3.2% in an account. How much money is in the account after the growth? Express your answer to two decimal places.
Answer:
To find out how much money is in the account after the growth, we can use the formula:
FV = PV(1+r)
Where FV is the future value of the account, PV is the present value of the account, and r is the rate of growth expressed as a decimal.
In this case,
PV = $225
r = 3.2% = 0.032 (as a decimal)
By substituting the values in the formula:
FV = PV(1+r)
FV = $225 * (1 + 0.032)
FV = $225 * 1.032
FV ≈ $232.7 (rounded to two decimal places)
Therefore, the account has $232.7 after the growth of 3.2%.
Answer: $232.20
Step-by-step explanation:
3.2%=0.032
225x0.032=7.2
225+7.2=232.2

The expression 2x + 4x represents the cost of buying the same number of cases of spring water, sold for $2 per case, and sparkling water, sold for $4 per case. What expression can be used to express the total cost?
Answer: 2x + 4x = (2 + 4)x = 6x
Step-by-step explanation:
The expression 2x + 4x represents the cost of buying the same number of cases of spring water and sparkling water. To express the total cost, we need to add the cost of buying the two types of water.
Since the expression 2x represents the cost of buying x cases of spring water, and 4x represents the cost of buying x cases of sparkling water, the total cost can be expressed as:
2x + 4x = (2 + 4)x = 6x
Therefore, the total cost of buying x cases of spring water and sparkling water can be expressed as 6x.
Alternatively, you can think of it as buying x cases of spring water at a cost of 2x dollars and x cases of sparkling water at a cost of 4x dollars. So the total cost is (2x+4x) dollars which is 6x dollars.

Mr. Baxter has 250 students. Of the 250 students, 130 are girls. What is the ratio of the boys to the total number of students in Mr. Baxter's class
Answer:
It is 12boys:13girls
Step-by-step explanation:
The total is 250 out of which 130 are girls. So it is 250-130 which is 120boys. Now to find the ratio it is 120:130 which in its simplest form is 12 boys:13 girls.

Use the tape diagram to find the value of 1/2 / 1/3. Show your reasoning.
Answer:
5/6
Step-by-step explanation:
In fractions, you can convert 1/2 and 1/3's denominators into a common number.
First, multiply 2 by 3 and 3 by 2. The denominator will be 6
Then, multiply the top by the same number (the numerator)
1/2*3/3 = 3/6.
1/3*2/2=2/6
3/6+2/6=5/6
Answer: 1.5, 1 1/2
Step-by-step explanation:
1/2 / 1/3
reciprocal of 1/3 is 3/1
1/2 x 3/1 = 3/2 = 1 1/2

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

I just need "Will this be true for any positive value of x?Justify your response" I will put you brainiest!
Answer: This situation cannot be true for any positive value of x. The valid range would be 0 < x < 4. If the x is less than 4, the perimeter of triangle 1 is always greater than triangle 2.
Explanation: We need to add up the lengths of the sides for obtaining the perimeters first.
Triangle 1: 5x + 57
Triangle 2: 11x + 33
Then, we need to build up an inequality for the case which the perimeter of triangle 1 is always greater than triangle 2.
This means => 5x + 57 > 11x + 33
If we write "x" values on one side:
24 > 6x
Then dividing by 6 for both sides:
4 > x
This means that a positive value of x should be less than 4 for this particular situation.
