Answer:

It is needed [tex]\frac{8}{5}[/tex] cups of yellow paint to mix with one cup

of red paint

Step-by-step explanation:

* Lets explain how to solve the problem

- To make the orange pint, Roger mixed 5/8 cup of red paint to one

 cup of yellow paint

∴ The ratio of red paint to yellow paint is 5/8 : 1

- Lets simplify it by multiplying the two terms of the ratio by 8

∵ [tex]\frac{5}{8}(8):1(8)[/tex]

∴ The ratio of red paint : yellow paint = 5 : 8

∴ For every 5 cups of red paint we need 8 cups of yellow paint to

  make the orange paint

- We need to know how many yellow paint is needed to mix with

 one cup of red paint

∵     red paint        :        yellow paint

            5               :                 8

             1               :                 ?

- By using cross multiplication we can find the number of yellow cups

∴ The number of the yellow cups = [tex]\frac{1*8}{5}=\frac{8}{5}[/tex]

∴ It is needed [tex]\frac{8}{5}[/tex] cups of yellow paint to mix with one

  cup of red paint

Answer:

The answer would be 3.

Step-by-step explanation:

This can be found by subtracting 12 from both sides and then the x will be alone on one side and be set equal to 3 on the other side.

Answer:

x = 6; ∠ONP = 24°

Step-by-step explanation:

1. Find the value of x

[tex]\begin{array}{rcl}\angle MNP & = & \angle MNO + \angle ONP\\3x^{2} + 12 & = & x^{2} + 10x + x^{2} - 2x\\3x^{2} + 12 & = & 2x^{2} + 8x\\x^{2} + 12 & = & 8x\\x^{2} -8x + 12 & = & 0\\(x - 2)(x - 6) & = & 0\\\end{array}[/tex]

[tex]x = 2 \text{ or }x = 6[/tex]

2. Find the measures of the angles

(a) x = 2

∠ ONP = x² - 2x = 2² - 2(2) = 4 - 4 = 0

This answer does not make sense because O lies in the interior of ∠MNP.

We disregard x = 2.

(b) x = 6

∠ ONP = x² - 2x = 6² - 2(6) = 36 - 12 = 24

Answer:

(2x6)+6

2x6=12

12+6=18

Final answer:

Two-step equations that equal 18 can be solved by performing two operations to isolate the variable, such as subtracting and then dividing, or adding and then dividing.

Explanation:

A student is asking for examples of two-step equations that result in an answer of 18. Two-step equations involve performing two operations to solve for the unknown variable. For instance, a simple two-step equation could be x/2 + 5 = 14, where you would first subtract 5 from both sides to get x/2 = 9, and then multiply both sides by 2 to find x = 18.

Another example could be 2x - 4 = 32. To solve this equation, you would first add 4 to both sides, resulting in 2x = 36, and then divide both sides by 2 to get x = 18.

These examples help students understand how to manipulate equations using addition, subtraction, multiplication, or division to isolate the variable and solve the equation.

Liam is incorrect

He spent $3 on the comic book

Step-by-step explanation:

Let

x -----> represents the amount of money he spent

we know that

The amount of money he spent plus the money he had left must be equal to the money he had when he walked into the store.

so

The linear equation that represent this problem is

x+5=8

solve for x

subtract 5 both sides

x=8-5=$3

Answer:

Step-by-step explanation:

Given

6x² - 2x + 36 = 5x² + 10x ( subtract 5x² + 10x from both sides )

x² - 12x + 36 = 0 ← in standard form

(x - 6)² = 0 ← in factored form, thus

x - 6 = 0 ⇒ x = 6 → D

The product of six and three less than the number is 6(x - 3) where x is the variable.

It is defined as the combination of constants and variables with mathematical operators.

The question is incomplete.

The complete question is:

Write the mathematical expression, and use x as a variable.

The product of six and three less than the number

x is the variable;

Three less than a number = x - 3

The product of 6 and (x - 3)

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

= 6(x - 3)

Thus, the product of six and three less than the number is 6(x - 3) where x is the variable.

You divide like regular and you get the answer even if it seems long

Answer:

~$6.6

Step-by-step explanation:

Tom's best strategy would be to keep a minimum balance of $1,000 in his CD to meet his bank minimum requirement.

From the given information, Tom's income can change from month to month and he needs to withdraw money from his CD to pay monthly bills, he should plan ahead and withdraw the necessary amount in one go to minimize the number of early withdrawals.

Withdrawing $250.00 from his CD every month for bills would result in multiple early withdrawals, incurring multiple penalties.

Thus, Tom's best strategy would be to keep a minimum balance of $1,000 in a separate CD for longer-term savings and avoid multiple early withdrawals.

Also he should keep the majority of his funds in a regular savings account or money market account for more flexibility in managing his irregular income and monthly expenses.

Answer:

f(2)=0

f(-4)=24

Step-by-step explanation:

We are given

f(n)=n^2-2n

We are asked which of the following are true?

f(2)=0

f(1)=3

f(-4)=24

f(5)=35

f(-2)=0

Let's start with f(2)=0.

f(2)=2^2-2(2)

f(2)=4-4

f(2)=0

So f(2)=0 is true.

Moving on to f(1)=3.

f(1)=1^2-2(1)

f(1)=1-2

f(1)=-1

So f(1)=3 is false.

Now for f(-4)=24.

f(-4)=(-4)^2-2(-4)

f(-4)=16+8

f(-4)=24

So f(-4)=24 is true.

f(5)=35?

f(5)=5^2-2(5)

f(5)=25-10

f(5)=15

So f(5)=35 is false.

Finally f(-2)=0.

f(-2)=(-2)^2-2(-2)

f(-2)=4+4

f(-2)=8

So f(-2)=0 is false.

Answer:

The correct option are,

f(2) = 0, and f(-4) = 24

Step-by-step explanation:

Given function,

[tex]f(n) = n^2 - 2n[/tex]

By substituting n = 2,

[tex]f(2) = 2^2 - 2(2) = 4 - 4 = 0[/tex]

By substituting n = 1,

[tex]f(1) = 1^2 - 2(1) = 1 - 2 = -1[/tex]

By substituting n = -4,

[tex]f(-4) = (-4)^2 - 2(-4) = 16 + 8 = 24[/tex]

By substituting n = 5,

[tex]f(5) = (5)^2 - 2(5) = 25 - 10 = 15[/tex]

By substituting n = -2,

[tex]f(-2) = (-2)^2 - 2(-2) = 4 + 4= 8[/tex]

Answer:

19,549

Step-by-step explanation:

If 26,000 ( I'll assume you missed a 0) is 33% more than their total the previous year.

If the previous year is supposed to be 100%, this year is 100% + 33% = 133%

Using rule of three:

26,000 -> 133%

x -> 100%

x = 100/133 * 26,000 = 19,549

The triangle can be a right triangle according to the Pythagorean theorem.

To determine if a triangle is a right triangle, we can use the Pythagorean theorem. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (hypotenuse).

In this case, the lengths of the sides are 3, 3, and 3√2. Let's calculate: (3)² + (3)² = 18 and (3√2)² = 18. Since the two values are equal, the triangle satisfies the Pythagorean theorem and can be a right triangle.
