8xy + 14x + 4x - 2xy + 6y

1+5=12x-10x

6=2x

6/2=2x/2

15 is 30% of 50. This is found by setting up a proportion: 15/50 = Percent/100, solving for Percent gives 30.

Let's call the part we're trying to find the percent of the "portion."

Portion = 15 (the value you want to find the percent of)

Total = 50 (the total value or whole)

Set up the proportion.

The ratio of the portion to the total as a percent, so we can set up a proportion:

Portion / Total = Percent / 100

Plug in the values.

Portion / 50 = Percent / 100

Solve for the percent:

Portion × 100 = 50 × Percent

Divide both sides by 50:

Percent = (Portion × 100) / 50

Calculate the percent:

Percent = (15 × 100) / 50

Percent = 1500 / 50

Percent = 30

Therefore, 15 is 30% of 50.

Answer: 4/10 + 1/5 = 0.6 and  4/10 - 1/5 = 0.2.

Step-by-step explanation:

1. Convert the fractions into decimals by dividing the numerator(the number to the left or top of the fraction) by the denominator(the number to the right or bottom of the fraction.

2. For the first question, add the two decimals to get your answer. For the second question, you subtract. 0.4-0.2.

Answer:

G

Step-by-step explanation:

a + b + c = 80

Express a and c in terms of b using the ratios in fractional form, that is

[tex]\frac{a}{b}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )

3a = 2b ( divide both sides by 3 )

a = [tex]\frac{2}{3}[/tex] b

[tex]\frac{b}{c}[/tex] = [tex]\frac{3}{11}[/tex] ( cross- multiply )

3c = 11b ( divide both sides by 3 )

c = [tex]\frac{11}{3}[/tex] b

Substitute the values for a and c into the original equation

[tex]\frac{2}{3}[/tex] b + b + [tex]\frac{11}{3}[/tex] b = 80 ( multiply through by 3 to clear the fractions )

2b + 3b + 11b = 240 , that is

16b = 240 ( divide both sides by 16 )

b = 15 → G

Answer and Step-by-step explanation:

To find the third side, we can use the Pythagorean Theorem.

The theorem states that if a triangle is a right triangle, and we already have two sides, we are able to find the third side.

The Pythagorean Theorem Formula is the following:

[tex]A^2+B^2=C^2[/tex]

A is any of the bases

B is the other base (you can make this the height)

C is the hypotenuse (the longest side)

We are given B and C, so lets plug them into our formula and solve for A.

[tex]A^2 + (4\sqrt{3} )^2=8^2[/tex]

Subtract [tex](4\sqrt{3} )^2[/tex] from both sides of the equation.

[tex]A^2=8^2 - (4\sqrt{3} )^2[/tex]

Now take the square root of both sides of the equation.

[tex]A=\sqrt{8^2 - (4\sqrt{3} )^2}[/tex]

Now plug this into your calculator and solve.

We get the answer to be:

4

a² = 16

a = √16

a = 4

Answer:

Explanation:

The number 43 is basically 40+3

We read "43" as "forty three", in which you can think of having 40 and then an additional 3 on top of that to get 40+3 = 43 overall.

As for the decimal portion, we do the same sort of thing.

The 0.205 breaks up into 0.2 + 0.005

0.2 = 2 tenths

0.005 = 5 thousandths

So that's why 43.205 breaks down into 40+3+0.2+0+0.005; each place value digit corresponds to a term in that expanded sum.

The value of the expression (x² + 3x + 2) × (2x² + 3x - 1) will be 2x⁴ + 9x³ - 12x² + 3x - 2.

When the relevant components and basic processes of a numerical method are given values, the expression's result is the result of the computation it depicts.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ (x² + 3x + 2) × (2x² + 3x + 1)

Simplify the equation, then we have

⇒ (x² + 3x + 2) × (2x² + 3x - 1)

⇒ x²(2x² + 3x - 1) + 3x(2x² + 3x - 1) + 2(2x² + 3x - 1)

⇒ 2x⁴ + 3x³ - x² + 6x³ + 9x² - 3x + 4x² + 6x - 2

⇒ 2x⁴ + 9x³ - 12x² + 3x - 2
