Answer:

4cm.

Step-by-step explanation:

let x represent the missing number.

From the question:

7 + x = 11

x = 11 - 7 = 4cm.

Answer:

The correct answer is third option N K

Answer:

NK

Step-by-step explanation:

Answer:

17. x = -2

18. All real numbers

19. No solution

Step-by-step explanation:

17. 10z + 26 = -3z

    -10z            -10z

26 = -13z

Divide both sides by -13

-2 = x

18. 4(3x - 5) = 2(6x - 10)

Distribute the 4

12x - 20 = 2(6x - 10)

Distribute the 2

12x - 20 = 12x - 20

Both sides are equal

All real numbers

19. 6m - 3 = 3(2m - 4)

Distribute the 3

6m - 3 = 6m - 4

     +3             +3

6m = 6m - 1

-6m   -6m

0 = -1

No solution

Answer:

(1+7v) (3u+8b)

Step-by-step explanation:

Hope this helps!!

The required solution would be (1+7v)(3u+8b) of the given expression.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have been given the expression as:

⇒ 21uv + 8b + 3u + 56bv

There is v common in 21uv and 56bv

There is b common in 8b and 56bv

There is u common in 21u and 3u

We have to Add and subtract the second term to the expression and factor by grouping, we get

⇒  (1+7v)(3u+8b)

Therefore, the required solution would be (1+7v)(3u+8b) of the given expression.

Answer: 62 Ft

Step-by-step explanation:

The shadow adds 13ft

How we know- 19 1/2 - 6 1/2 = 13 ft

So we need to take away 13ft to find out the goal post actual height

75-13= 62

Answer:

Step-by-step explanation:

10000*4%= 400 Geese year1

10400*4%=416 Geese  year 2

10816*4%= 432.64 Geese year 3

11,248.64*4%= 449.95 Geese. year 4

11248.64+449.95= 11698.59

11698.59-10000=1698.59

Increased by 1699 Geese.

Answer: 16

Answer:

a= -4

b=1

Step-by-step explanation:

Midpoint=(1,-3)=(x,y)

A=(-6,-7)=(x1,y1)

Let ,the coordinates of B be 'a and b' .

So,

B=(a,b)=(x2,y2)

Using ,midpoint formula,

(x,y)=(x1+x2\2 , y1+y2 \2)

or, (1,-3)=(-6+a\2 , -7+b \2)

Now,

Taking the corresponding sides,

or, 1 =-6+a/2

or, 1*2=6+a

or, 2=6+a

or, 2-6=a

a=-4

Then,

-3= -7+b/2

or, -3*2= -7+b

or, -6 =-7+b

or, -6+7=b

b=1

Step-by-step explanation:

Supplementary angles are angles that add up to 180 degrees. Essentially, you can make a straight line with them.

1 and 7 are supplementary

1 and 4 are verticle, so no.

2 and 6 are complementary, so no.

3 and 6 are complementary, so no.

Answer and explanation:

The gambler's fallacy is the fallacy of belief that if an event such as a loss occurs more frequently in the past, it is less likely to happen in the future. We assume here that this belief is true, therefore

If she loses, her probability of winning increases =3/4

If she wins, her probability to win is normal =1/2

Given that probability of winning is 1/2

Probability of losing is 1-1/2=1/2

Probability that she wins the tournament is probability that she wins the first two games and loses the last or wins the first game, loses the second and wins the last or loses the first game and wins the last two games or probability that she wins all three games

=1/2*1/2*1/2+1/2*1/2*3/4+1/2*3/4*1/2+1/2*1/2*1/2

=25/48

Probability of winning the tournament if she loses the first game

=1/2*3/4*1/2= 3/16

Note: whenever there is "or" in probability, you add

Answer:

Orge has $50 left in his checking account.

Step-by-step explanation:

Answer:

120 (60 from each store)

Step-by-step explanation:

Given that:

Price for 10 pack of pencils at SupplyCo = $0.95

Price for 10 pack of pencils at SchoolShop = $1.45

Discount coupon at SchoolShop = $3.00

Let the number of packs of pencils bought = [tex]2x[/tex] (in pack of 10)

Then [tex]x[/tex] will be the number of packs of 10 bought at each store.

Therefore, price at SupplyCo for [tex]x[/tex] packs (in pack of 10) = [tex]0.95x[/tex]

And price at SchoolShop for [tex]x[/tex] packs (in pack of 10) = [tex]1.45x-3.00[/tex] (because there is a coupon of $3.00)

As per question statement, price at both the stores is same:

[tex]0.95x=1.44x-3\\\Rightarrow 0.5x=3\\\Rightarrow x=6[/tex]

Therefore, number of packs bought = [tex]2x\times 10 = 2\times 6\times 10 =\bold{120}[/tex] (60 from each store)

Answer:

y=1/2x+b

Step-by-step explanation:

-x+2y=4 = 2y=x+4

2y/2=(x+4)/2 = y=1/2x+2

1=1/2(-2)+b = 1=-1+b = 2=b

y=1/2x+2

Answer:

After the reflection over the line y=x, the image points are:

Step-by-step explanation:

We know that when a point is reflected cross the line y = x, the x-coordinate, and y-coordinate change places.

i.e.

Given

so after the points reflected cross the line y = x

P(x, y)                 →          P'(y, x)

A(-2, -1)               →          A'(-1, -2)    

B(-1, 3)                →          B'(3, -1)  

C(-3, 2)               →          C'(2, -3)

Therefore, after the reflection over the line y=x, the image points are:

Answer:

5<4

Step-by-step explanation:

This inequality is not correct though.

5-7+7<-3+7

5<4

If you are considering speed regardless of direction, the average speed is:

(24 + 16) / 2 = 40 / 2 = 20mph

Although if direction matters, then one number has to be negative since the directions are opposite:

(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)

Answer:

3x+1=2x+40

We move all terms to the left:

3x+1-(2x+40)=0

We get rid of parentheses

3x-2x-40+1=0

We add all the numbers together, and all the variables

x-39=0

We move all terms containing x to the left, all other terms to the right

x=39

Step-by-step explanation:

Answer:

x = 48

Step-by-step explanation:

Original equation:

1/3x + 1/2x = 40

Add 1/3x to 1/2x

5/6x

Equation Now:

5/6x = 40

Divide both sides by 5/6

x = 48

Answer:

Yes, Nevan wins = 96

Step-by-step explanation:

58(7/4)-22(1/4) = 96

Step-by-step explanation:

Original cost = 900

Cost after VAT = 990

VAT amount = 990 - 900 = 90

Rate of VAT = 90/900×100 = 90/9 = 10%

Answer:

yes

Step-by-step explanation:

If 2 lines are perpendicular then the product of their slopes = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x - 4 ← is in slope- intercept form

with slope m = - 1

5x - 5y = 20 ( subtract 5x from both sides )

- 5y = - 5x + 20 ( divide all terms by - 5 )

y = x - 4 ← in slope- intercept form

with slope m = 1

Thus product of their slopes is - 1 × 1 = - 1

Therefore the lines are perpendicular
