This year, lashonda watched 85 movies. She thought that 34 of them were very good. If the movies she watched, what percentage did she think were very good

Answer:

x=2

Step-by-step explanation:

first you distribute the two on the left side of the equation and get 2x+10= -10x+34. Then add 10x to both sides of the equation to get 12x+10=34. Then subtract 10 from both sides of the equation to get 12x=24. finally divide both sides of the equation by 12 and get x=2

Answer: V/D = T

Step-by-step explanation:

From the figure shown where MN is parallel to PQ:

m<MSR   =  100°

m<STQ   =  80°

By carefully observing the figure shown:

<MSR is vertically opposite to <NST

Vertically opposite angles are equal

m<NST  =  (17x  +  15)

<NST is alternative to <PTS

Alternative angles are equal

Therefore, m<NST  =  m<PTS

m<NST = 17x + 15

m<PTS  =  19x + 5

17x  +  15   =  19x  +  5

19x  -  17x =  15  -  5

2x   =  10

x   =  10/2

x   =  5

m<NST  =  17x + 15

m<NST  =  17(5)  +  15

m<NST  =  100°

Since m<MSR  =  m<NST

m<MSR   =  100°

m<PTS  =  19x + 5

m<PTS  =  19(5)  +  5

m<PTS  =  100°

m<PTS  +  m<STQ  =  180° (Sum of angles on a straight line)

100   +  m<STQ   =  180

m<STQ   =  180 - 100

m<STQ   =  80°

From the figure shown where MN is parallel to PQ:

m<MSR   =  100°

m<STQ   =  80°

Answer:

79, 81, 83, and 85

Step-by-step explanation:

x = 1st integer

x+2 = 2nd

x+4 = 3rd

x+6 = 4th

328 = sum

x+x+2+x+4+x+6 = 328

328/4 = 82

The 4 integers are the 2 odd integers on either side of 82 and closest to 82

That would be 79, 81, 83, and 85.

79 + 81 + 83 + 85 = 328

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

The domain of the function (cd)(x) will be all real values of x except x = 2.

Step-by-step explanation:

The two functions are c(x)=

[tex] \frac{5}{ \times - 2} [/tex]

and d(x) = x + 3

So, (cd)(x) =

[tex]( \frac{5}{ \times - 2} )( \times + 3) = 5\frac{( \times + 3)}{ \times - 2} [/tex]

Therefore, the domain of the function (cd)(x) will be all real values of x except x = 2. (Answer)

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:

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

Step-by-step explanation:

False because if 3 is subtracted from 52, then 49 and 27 more would not equal 49 and 24 more. Putting together two larger numbers is not the same as putting together two smaller numbers.

=======================================================

Explanation:

If we break up 52 into 49+3, then we can do the following rearrangement.

52 + 27 = 49 + 24

49 + 3 + 27 = 49 + 24

3 + (49+27) = 49 + 24

Notice that the 49+27 on the left is clearly larger than 49+24 on the right, mainly due to the 27 being larger than 24.

Then adding on 3 more means that the left side gets even larger.

So without having to add either side and simplify fully, we can see that the left side is larger than the right side. There's no way the two sides are the same number.

----------

Perhaps another quick way is to simply look at the units digits.

The 2 and 7 from 52 and 27 add to 2+7 = 9

The 9 and 4 from 49 and 24 add to 9+4 = 13 and we only care about the 3

The mismatch of the 9 and 3 is more evidence that the two sides aren't the same number.

Answer:

Step-by-step explanation:

1. In a group of cows and chickens, the number of legs was 14 more than twice the number of heads. The number of cows was:

(a) 5, (b) 7, (c) 10, (d) 12, (e) 14

Solution:

Let the number of cows be x and their legs be 4x.

Let the number of chicken be y and their legs be 2x.

Total number of legs = 4x + 2y.

Total number of heads = x + y.

The number of legs was 14 more than twice the number of heads.

Therefore, 2 × (x + y) + 14 = 4x + 2y.

or, 2x + 2y + 14 = 4x + 2y.

or, 2x + 14 = 4x [subtracting 2y from both sides].

or, 14 = 4x – 2x [subtracting 2x from both sides].

or, 14 = 2x.

or, x = 7 [dividing by 2 on both sides].

Therefore, the number of cows = 7.

Answer:

Which expression is equal to “8 less than the product of y and 9"'?​

Step-by-step explanation:

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

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