Rosie is making a special green paint it contains 2/3 cups yellow paint 1/3 cups white paint 1 and 1/5 blue paint and 1/5 black paint what percentage of the green paint is blue

Answer:

a) y=200x+450

b) y=200(8)+450 = $2050

c) 21 months

Step-by-step explanation:

a) y=200x+450

200 per month plus her initial deposit of 450

b) y=200(8)+450 = 2050

To see how much she'll have after 8 months, plug in 8 for x

c) 4500<200x+450

4050<200x

20.25<x

x>20.25, so after 21 months since 20.25 is more than 20 months you have to round up to 21

Answer:

this is a binomial, but its 2x^2-10x+8

Step-by-step explanation:

you use the distributive property

So we know that the number x is multiplied by 4, and then is bigger then itself by 45, so so lets set up this equation.

4x = x + 45

The 4x is our x multiplied by 4 and the x + 45 is when it exceeds itself by 45.

Now lets solve:

4x = x + 45

Bring x to one side to isolate the variable:

4x - x = 45

3x = 45

Now we divide the 3 from the 3x in order to fully isolate the variable:

x = 45 / 3

x = 15

Lets plug 15 in to double check the answer:

4(15) = 15 + 45

60 = 60

Yes!

This means that 15 is the number multiplied by 4 and exceeded by 45.

I hope this helps! :)

Answer:

20 hours

Step-by-step explanation:

20 hours, since you have to find the remaining 80% of her dance time.

I thought of this as follows:

1/5 = 4

2/5 = 8

3/5 = 12

4/5 = 16

5/5 (100% of her dance time!) = 20 hours!

Answer:

36%

Step-by-step explanation:

47/132=36%

The = is means the equal sign with the ~ position

The percent of the students prefer superhero movies rounded to the nearest percent is; 36%

The table of this random survey of students when seen online tells us that;

Total number of students that prefer super hero movies = 47

Total Number of Students that prefer Comedy = 50

Total Number of Students that prefer drama = 35

Thus;

Total number of students surveyed = 47 + 50 + 35

Total number surveyed = 132

Thus;

Percent of the students that prefer superhero movies = 47/132 * 100%

Percent of the students that prefer superhero movies = 36%

Step-by-step explanation:

Given info:- 5/(x-3) - 4/(x+4) = 1/x. And here the problem has asked to find out the value of x ?

Let's solve!!

Given equation is 5/(x-3) - 4/(x+4) = 1/x

⇛ [5(x+4) - 4(x-3)]/(x-3)(x+4) = 1/x

⇛ (5x+20-4x+12)/(x-3)(x+4) = 1/x

⇛ (x+32)/(x-3)(x+4) = 1/x

On applying cross multiplication then

⇛ x(x+32) = (x-3)(x+4)

⇛ x²+32x = x(x+4)-3(x+4)

⇛ x²+32x = x²+4x-3x-12

⇛ x²+32x = x²+x-12

⇛ x²+32x-x²-x = -12

⇛ (x²-x²)+(32x-x) = -12

⇛ 0+31x = -12

⇛ 31x = -12

⇛ x = -12/31

∴ x = -12/31

The value of x for the given problem -12/31

VERIFICATION:

Check

If x = -12/31 then LHS of the equation is

5/(x-3) - 4/(x+4)

⇛ 5/[(-12/31)-3] -4/[(-12/31)+4]

⇛ 5/[(-12-93)/31] -4/[(-12+124)/31]

⇛ 5/(-105/31) - 4/(112)/31

⇛ (5×-31)/105 - (4×31)/112

⇛ (-115/105)-(124/112)

⇛ (-31/21) - (31/28)

⇛ (-31)[(1/21)+(1/28)]

⇛ (-31)(21+28)/(21×28)

⇛ (-31×49)/(21×28)

⇛ (-31×7)/(21×4)

⇛-31/12

And RHS = 1/x

⇛ 1/(-12/31)

⇛ -31/12

⇛ LHS = RHS is true for x = -31/12

Answer:

x = 1

Step-by-step explanation:

Here is what you need to know:

f(x) represents the y-value.

The x in the parenthesis represents the x-value.

Another way to write f(x) = 1 is y = 1.

So now you are just finding the x-value for when y = 1. Looking at the graph, when y is 1 ( 1 on the y-axis), x has to be 1! This is because when you go up one, the only value that matches that point is 1!

Answer:

Point-slope equation: y - 10 = 2(x - 3)

Step-by-step explanation:

Given the slope of the line, m = 2, and the point, (3, 10):

Let the slope (m) = 2

                 (x₁, y₁) = (3, 10)

Substitute these values into the point-slope form, y - y₁ = m(x - x₁):

y - y₁ = m(x - x₁)

y - 10 = 2(x - 3)  ⇒ This is the point-slope form.
