Step-by-step explanation:

Answer:

-2, 0, 2, 4, 6  these are the answers for the boxes and they are in order. solution x<1

Step-by-step explanation:

if you look at the box you will see that it says x and 2x at the bottom. The x at the top is the same as the one at the bottom. So they want you to multiply the number in the row of x by the number below x I hope this helps

Answer:

x = 20

Step-by-step explanation:

If A || B, then ∠2 should equal to ∠3 (Alternate angles).

3x - 10 = x + 30

Isolate like terms.

3x - x = 30 + 10

Evaluate like terms.

2x = 40

Find x.

x = 40 ÷ 2

x = 20

Answer:

x = 20.

Angles 2 and 3 are measured as 50 degrees.

Step-by-step explanation:

Angles 2 and 3 are congruent, meaning that they are equal.

Set the two equations equal to each other and solve for x.

3x-10=x+30 (subtract x from the left side and add 10 to the right. This gets the x's and the plain numbers on the same side of the equation)

2x=40 (Divide by 2)

x = 20

Check your work by plugging in 20 for x in each expression. If the two expressions are equal when you do so, then you know you've worked out the problem correctly.

Angle 2:

3(20)-10

60 - 10 = 50

Angle 3:

20 + 30 = 50

Both expressions equal 50 when plugging in 20 for x, so this is the correct answer.

Answer: The number is 974

Step-by-step explanation:

First, any 3 digit number can be written as:

N = a*100 + b*10 + c

Where a, b, and c are single-digit numbers.

a is the hundreds digit

b is the tens digit

c is the unit digit

We can write the clues as:

#1: a + b + c = 20

#2: b = a - 2

#3: c = a + b - 12

Then we have a system of equations:

a + b + c = 20

b = a - 2

c = a + b - 12

To solve this, we need to isolate one of the variables in one equation and then replace this in the other equations, we can see that b is already isolated in the second equation, then we can replace that in the first and third equations:

a + (a - 2) + c = 20

c = a + (a - 2) - 12

Now we can see that c is isolated in the second equation, then we can replace that in the first one to get:

a + (a - 2) + (a + (a - 2) - 12) = 20

Now we can solve this for a:

a + a - 2 + a + a -2 - 12 = 20

4*a - 16 = 20

4*a = 20 + 16

4*a = 36

a = 36/4 = 9

With this, we can find the values of b and c.

b = a - 2 = 9 - 2 = 7

c = a + b - 12 = 9 + 7 - 12 = 4

Then the 3-digit number is:

N = a*100 + b*10 + c = 9*100 + 7*10 + 4 = 974

N = 974

Answer: The shirt's price after reduction = $ 84.15

Step-by-step explanation:

Given: Price of shirt= $ 85

Marked up percent = 10%

Reduced percent = 10%

Price after mark up = (Price of shirt) + 10% of (Price of shirt)

= $ (85+10% x 85)

= $ (85+(0.1) x (85))

= $ (85+8.5)

= $ 93.5

Price after 10% reduction = (Price after mark up)- 10% of (Price after mark up)

= $ (93.5-0.1 x 93.5)

= $ (93.5-9.35)

= $ 84.15

Hence, the shirt's price after reduction = $ 84.15

Answer:

Length=8 Width=5

Step-by-step explanation:

Set this up as a system of equations with l standing for length and w standing for width.

w+3=l

l×w=40

Substitute rhe first equation into the 2nd one.

w(w+3)=40 --------> w^2+3w=40

Move all the terms to the left side

w^2+3w-40=0

Factor

(w+8) (w-5)

Set both factors equal to 0.

w+8=0 -----> w=-8

w-5=0 ------> w=5

Since distance cannot be negative we can eliminate -8. So w=5

Plug it back into any one of the equations and solve for l.

5+3=l -----> 8=l

So the answer is the length is 8 and the width is 5.

The dimensions of the rectangle are:

Length = 8 meters.

width = 5meters.

We are given that the length of a rectangle is 3 meters longer than its width and the area of a rectangle is 40 square meters.

We need to find the length and width of the rectangle.

A rectangle is a closed 2-dimensional shape that has two dimensions, the length, and the width. Length is the longer side and width is the shorter side of the rectangle.

The area of a rectangle is given by :

A = Length x Width.

Let the area, length, and width of the rectangle be A, L, and W.

The length of a rectangle is 3 meters longer than its width.

We can write it as,

L = 3 + W

The area of a rectangle is 40 square meters.

We can write it as,

A = 40 square meters

We can write it as,

L x W = 40

Substituting  L = 3 + W.

(3 + W) W = 40

[tex]3W + W^2 = 40\\W^2 + 3W = 40 \\W^2 + 3W - 40 = 0[/tex]

This is a quadratic equation and we will apply middle-term factorization.

[tex]W^2 + 3W - 40=0\\W^2 + (8-5)W - 40=0\\W^2 + 8W - 5W - 40=0\\W(W + 8) - 5 ( W + 8)=0\\(W+8)(W - 5)=0\\W+8 = 0~~and~~W-5=0\\W = -8~~and~~W=5[/tex]

The distance can not be negative so W = -8 is eliminated.

We have, W = 5

Substituting W = 5 in L = 3 + W.

We get,

L = 3 + 5 = 8

L = 8.

The dimensions of the given rectangle are:

Length = L = 8 meters.

Width = W = 5 meters.

Answer:

x = -1/2

Step-by-step explanation:

First, subtract 2 from both sides to get 7/x alone. Then muliply both sides by x to get rid of 7/x's denominator. Divide both sides by -14 to get rid of x's coefficient and to get x alone. You will then get -1/2 as your answer.

2 + 7/x = -12

-2             -2

7/x = -14

*x       *x

7 = -14x

÷-14    ÷-14

- 1/2 =x

x = -1/2

Answer:

1) Between 0 and 1 minute the rate of change is 25 ft./min

2) Between 1 and 2 minute the rate of change is 0 ft./min

3) Between 2 and 4 minute the rate of change is -12.5 ft./min

Step-by-step explanation:

1) Between 0, and 1 feet, we have;

The rate of change = (Final height - Initial height)/(Final time - Initial time)

The rate of change = (40 - 15)/(1 - 0) = 25 ft/min

Between 0 and 1 minute the rate of change = 25 ft./min

2) Between 1, and 2 feet, we have;

The rate of change = (40 - 40)/(2 - 1) = 0 ft/min

Between 1 and 2 minute the rate of change = 0 ft./min

3) Between 2, and 4 feet, we have;

The rate of change = (15 - 40)/(4 - 2) = -12.5 ft/min

Between 2 and 4 minute the rate of change = -12.5 ft./min

The value of x from the quadratic equation is x = { 2 , -12 }

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² + 10x = 24   be equation (1)

Adding 5² on both sides of the equation , we get

x² + 10x + 25 = 24 + 25

( x + 5 )² = 49

Taking square roots on both sides , we get

x + 5 = ±7

Subtracting 5 on both sides , we get

x = 2

And , x = -12

Hence , the quadratic equation is solved and value of x is x = -12 or x = 2
