Gabby's 35 boxes plus Ross's b amount of boxes equals the 69 boxes

The Answer is: y=2,5

Answer:

y = -5

y = 2

Step-by-step explanation:

Find 2 factors of -10 that add up to 3

This will be 5 and -2

So, we can factor this:

y² + 3y -10 = 0

(y + 5)(y - 2) = 0

Set each factor equal to 0 and solve:

y + 5 = 0

y = -5

y - 2 = 0

y = 2

So, the solutions are y = -5 and y = 2

Answers:

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

Explanation:

x = amount of the 95% concrete mix

y = amount of the 80% concrete mix

Type A mix has 95% concrete. If we have x pounds of this, then 0.95x pounds is pure concrete. Type B mix has 80% concrete. If there are y pounds of this, then 0.80y pounds is pure concrete.

So far we have 0.95x+0.80y pounds of pure concrete from the two mixes

Divide this over 30 to get (0.95x+0.80y)/30

Setting this equal to 0.90 means we want the final mix to be 90% concrete.

Since we want 30 pounds total, we can say x+y = 30 which solves to y = 30-x. We'll use this later

-------------------------------

(0.95x+0.80y)/30 = 0.90

0.95x+0.80y = 30*0.90 .... multiply both sides by 30

0.95x+0.80y = 27

0.95x+0.80(30-x) = 27 ..... plug in y = 30-x

0.95x+0.80*30-0.80*x = 27

0.95x+24-0.80x = 27

0.15x+24 = 27

0.15x = 27-24 ..... subtracting 24 from both sides

0.15x = 3

x = 3/0.15 ........... dividing both sides by 0.15

x = 20

y = 30-x

y = 30-20

y = 10

Answer:

3

Step-by-step explanation:

She only bought one chocolate so you will subtract 8.32 from her total, 27.79, when you do that you will get 19.47.  You do that so you can know the total of the stuffed animals by them self.  Then all you have left in the total is her stuffed animals so you divide 19.47 by 6.49, when you do that you get three, so that means that she got three stuffed animals.

Answer:

Step-by-step explanation:

Answer:

Option (C) and (D)

Step-by-step explanation:

Given piecewise function is,

f(x) = 2x, x < 1

        5, x = 1

        [tex]x^{2}[/tex], x > 1

Option (A),

x = 5 means x > 1

So the function will be,

f(x) = [tex]x^{2}[/tex]

f(5) = (5)²

     = 25

Therefore, f(5) = 1 is not correct.

Option (B),

x = -2 means x < 1

f(x) = 2x will be applicable.

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

Therefore, f(-2) = 4 is not correct.

Option (C)

For x = 1,

f(1) = 5

Therefore, f(1) = 5 is the correct option.

Option (D)

x = 2 means x > 1 and the function defined will be,

f(x) = x²

f(2) = 2²

     = 4

Therefore, f(2) = 4 will be the correct option.

Options (C) and (D) will be the answer.

Answer:

last option is correct because the standard form of polynomial means the arrangement of power in descending order

Answer:

62/78*( 1 6/8)

Answer: dark chocolate 16/25 carmel 1/12

Step-by-step explanation:

there are 16 dark chocolates

to find the probability you have to add up all of your numbers

2+7+16= 25

so the probablity of drawing a dark chocolate is 16/25

repeat the steps but subtract 1 from the total since you ate one you didn't put it back.  

so the probability of drawing a carmel is 2/24 or simplified 1/12

Answer:

1/2x -1/2

Step-by-step explanation:

f(x) = 2x+1

y = 2x+1

Switch x and y

x = 2y+1

Solve for y

Subtract 1

x-1 = 2y+1-1

x-1 =2y

Divide by 2

(x-1)/2 = 2y/2

1/2x -1/2 = y

The inverse is 1/2x -1/2

Answer:

[tex]\huge\boxed{h(x) = \frac{1}{2} x - \frac{1}{2}}[/tex]

Step-by-step explanation:

[tex]f(x) = 2x+1[/tex]

Put f(x) = y

[tex]y = 2x + 1[/tex]

Interchange x and y

[tex]x = 2y+1[/tex]

Solve for y

[tex]x = 2y+1[/tex]

Subtracting 1 to both sides

[tex]x-1 = 2y[/tex]

Dividing both sides by 2

[tex]\frac{x-1}{2} = y \\\\ OR\\\\ y = \frac{x-1}{2}[/tex]

Put y = h(x)

[tex]\bold{h(x) = \frac{1}{2} x - \frac{1}{2}}[/tex]

Answer:

Step-by-step explanation:

First of all cross multiply

That's

g( wd + f ) = a + bc

Multiply the terms at the left side of the equation

We have

gwd + fg = a + bc

Send fg to the right side of the equation

That's

gwd = a + bc - fg

Divide both sides by dg to make W stand alone

We have the final answer as

Answer:

3.75 cm^2

Step-by-step explanation:

Area of a rectangle = Length x Width.

If we are given that the length is 5 cm and width is 3/4 cm ( you could convert this to a 0.75 if you want to as well ) we can plug this in:

Area = 5 cm x 3/4 cm

Solving for Area we get:

Area = 3.75 cm^2.

Answer:

[tex] \boxed{ \bold{ \huge{ \bold{ \boxed{ \sf{3.75 \: {cm}^{2} }}}}}}[/tex]

Step-by-step explanation:

Length ( l ) = 5 cm

Width ( w ) = 3/4 cm

To find : Area of a rectangle

Finding the area of a rectangle having length of 5 cm and width of 3/4 cm

[tex] \boxed{ \sf{area \: of \: rectangle = \: l \times w}}[/tex]

plug the values

[tex] \dashrightarrow{ \sf{5 \times \frac{3}{4} }}[/tex]

To multiply one fraction by another, multiply the numerators for the numerator, and multiply the denominator for its denominator.

[tex] \dashrightarrow{ \sf{ \frac{5 \times 3}{4} }}[/tex]

[tex] \dashrightarrow{ \sf{ \frac{15}{4} }}[/tex]

Divide 15 by 4

[tex] \dashrightarrow{ \sf{3.75 \: {cm}^{2} }}[/tex]
