A chef wants to make 2 quarts of salad dressing. Currently, he has 18 parts oil, and 4 parts vinegar. How much oil must be added to get 24 parts oil and 3 parts vinegar? Write and solve an equation.

Answer:

A. Infinite solutions.

Step-by-step explanation:

3x - 2y = 12

6x - 4y = 24

The second equation can be formed by multiplying the first by 2. So if we graphed them they would give the same line. So the equations are identical and there are infinite solutions.

Answer:

Paul grew 6 inches in 2 years

Step-by-step explanation: he was 42 inches before now he is 48 inches

The number "4 ten thousands, 1 thousand, 9 hundreds, 8 tens, and 4 ones" written in standard form is 41,984.

To write the number 4 ten thousands, 1 thousand, 9 hundreds, 8 tens, and 4 ones in standard form, we can add up the value of each place:

4 ten thousands = 4 × 10,000 = 40,000

1 thousand = 1 × 1,000 = 1,000

9 hundreds = 9 × 100 = 900

8 tens = 8 × 10 = 80

4 ones = 4

Now, add up these values:

40,000 + 1,000 + 900 + 80 + 4

= 41,984

Therefore, the number "4 ten thousands, 1 thousand, 9 hundreds, 8 tens, and 4 ones" written in standard form is 41,984.

Answer: The 3 in 17,235 is in the tens digit and the 3 in 17,352 is in the hundreds digit

Answer:

5

Step-by-step explanation:

do reverse calculations

we know that we ended with 6

since 2 jumped out we add them back in

6+2 = 8

we remove the toads that jumped in because they are not part of the original group

8-3 = 5

there were 5 toads in the beginning

There were originally 5 toads in the pond. This is determined by reverse calculation of the toads jumping in and out.

To solve this math problem you can use a process of reverse calculation. At the end of the toad jumping in and out, there were 6 toads in the pond.

If we take into account the events that happened before we have that 2 toads jumped out so there must have been 8 toads before that(6 + 2).

Further back, 3 toads jumped in which means there must have been 8 - 3 = 5 toads in the pond to begin with.

So, initially, before any of the jumping happened, there were 5 toads in the pond.

Step-by-step explanation:

Answer:

22 Cups of soup Left

Step-by-step explanation:

Given: 2 gallons of soup and 10 cups of soup served to guest.

To find: No. of cups of soup left.

We know that , 1 US Gallon = 16 US cups

⇒ 2 gallon of soup = 2 × 16 = 32 cups of soup

So, Remaining No. of Cups of soup = 32 - 10

                                                          = 22

Therefore, 22 Cups of soup Left

5-2x2=-15

Two solutions were found :

                  x = ± √10 = ± 3.1623

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    5-2*x^2-(-15)=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (5 -  2x2) -  -15  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  20 - 2x2  =   -2 • (x2 - 10)

Trying to factor as a Difference of Squares :

3.2      Factoring:  x2 - 10

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 10 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Equation at the end of step  3  :

 -2 • (x2 - 10)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    x2-10 = 0

Add  10  to both sides of the equation :

                     x2 = 10

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:  

                     x  =  ± √ 10  

The equation has two real solutions  

These solutions are  x = ± √10 = ± 3.1623  

Two solutions were found :

                  x = ± √10 = ± 3.1623

To solve the equation 5 - 2x^2 = -15 using inverse operations, we need to isolate the variable x on one side of the equation.

1. Start by adding 15 to both sides of the equation to eliminate the constant term on the right side:

5 - 2x^2 + 15 = -15 + 15

20 - 2x^2 = 0

2. Next, divide both sides of the equation by -2 to isolate the x^2 term:

(20 - 2x^2) / -2 = 0 / -2

-10 + x^2 = 0

3. Now, move the constant term to the other side by adding 10 to both sides:

-10 + x^2 + 10 = 0 + 10

x^2 = 10

4. To solve for x, we need to take the square root of both sides of the equation:

√(x^2) = √(10)

x = ±√(10)

To check the solutions, substitute them back into the original equation and see if they make it true:

For x = √(10):

5 - 2(√(10))^2 = -15

5 - 2(10) = -15

5 - 20 = -15

-15 = -15 (True)

For x = -√(10):

5 - 2(-√(10))^2 = -15

5 - 2(10) = -15

5 - 20 = -15

-15 = -15 (True)

So, the solutions to the equation 5 - 2x^2 = -15 are x = √(10) and x = -√(10).

Answer:

1268

Step-by-step explanation:

4226-2958=1268 mark the brainliest

The difference between 4,226 and 2,958 is 1,268.

The question is asking for the difference between 4,226 and 2,958. To solve this, we subtract 2,958 from 4,226. Starting from the rightmost digit, subtract 8 from 6 which gives us 2. Then subtract 5 from 2 and you get a negative number so we need to borrow from the next digit. Borrow 1 from the leftmost digit, which makes it 3, then subtract 5 from 13 and you get 8. Finally, subtract 2 from 3, giving us 1. The answer is 1,268.

Answer:

4.59

Explanation:

1.38 + 2.01 = 3.39

1.2 = 1.20

3.39 + 1.20 = 4.59

Divide 1 by 8 which is 0.125, for a decimal. Then to turn it into a percent move the decimal 2 places to the right, then add the percent to the end; 12.5%

The fraction 1/8 can be converted into a decimal by dividing the numerator by the denominator, yielding 0.125. This decimal can then be converted into a percent by multiplying by 100, yielding 12.5%.

To convert the fraction 1/8 into a decimal and a percent, we need to perform two types of conversions: a fraction-to-decimal conversion and a decimal-to-percent conversion.

First, converting the fraction to a decimal. To convert a fraction to a decimal, divide the numerator (top number) by the denominator (bottom number). In this case, that gives us 1 ÷ 8 = 0.125.

Then, converting the decimal to a percent. A decimal can be converted to a percent by multiplying it by 100. So 0.125 * 100 = 12.5%. Therefore, the fraction 1/8 is equal to 0.125 as a decimal and 12.5% as a percentage.
