Answer:

All Real Numbers

Step-by-step explanation:

[tex]4(x + 6) = 2(2x + 12)[/tex]

divide both sides by 2

[tex]2(x + 6) = 2x + 12[/tex]

[tex]2x + 12 = 2x + 12[/tex]

this is enough to prove that it's all real numbers, but it can be simplified even more

[tex]2x=2x[/tex]

subtract 2x from both sides

[tex]0=0[/tex]

0 will always equal 0, so x is all real numbers

Answer:

Step-by-step explanation:

Equation of line with a given slope of a and containing a given point (x₀, y₀):

y - y₀ = a(x - x₀)

a = 1,  x₀ = -7,  y₀ = -5

Therefore:

y - (-5) = 1(x - (-7))  

y + 5 = x + 7

y = x + 7 - 5

y = x + 2

Answer:

2 4/5 feet

Step-by-step explanation:

let 'x' = height of fire hydrant

7/20 = x/8

cross-multiply:

20x = 56

x = 56/20 or 14/5, which is 2 4/5

Answer:

6m

Step-by-step explanation:

You need to use trigonomtery: SOHCAHTOA

Since we are looking for the height, we should use the Sine rule:

Sine(37) = opposite/hypotenuse

We already have our hypotenuse which is 10

sine(37) = opposite/10m

Now we re-arrange to find the opposite(which is our height)

opposite = 10m x sine(37)

opposite = 6.018

Therefore height = 6 to the nearest metre

Step-by-step explanation:

[tex]n=3*10*\frac{3}{2*2} =30*\frac{3}{4} =22.5 cans[/tex]

Answer:

You need 22.5 cans of paint to paint 10 walls with 3 layers.

Step-by-step explanation:

[tex]\frac{3}{2*2}[/tex] = 0.75 (Represents how many cans of paint it takes to paint 1 wall with 1 layer)

0.75 * 10 * 3 = 7.5 * 3 = 22.5 (The number of paint needed for 1 wall with 1 layer multiplied by 10 walls with 3 layers to get the total amount of paint needed)

Answer:

x = 12, 6

Step-by-step explanation:

Factor using the AC method.

Consider the form x² + bx + c. Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 72 and whose sum is -18.

-12, -6

Write the factored form using these integers.

(x - 12)(x - 6) = 0

If any individual factor on the left side of the equation is equal to  0, the entire expression will be equal to 0.

x - 12 = 0, x = 12

x - 6 = 0, x = 6

i hope this helps, good luck :)

Answer:

Option c = [tex]\sqrt[9]{3}[/tex]

Step-by-step explanation:

One side = 18

Bottom side = 18 (equalateral triangle)

we can use phytagorues theorum:

a = the altitude (unknown)

b= one side (half of the bottom side) = 18/2 = 9

c = hypothenus = 18 (given)

a^2 + b^2 = c^2

a^2 + 9^2 = 18^2

a^2 = 18^2 - 9^2

   a^2  = 243

a = [tex]\sqrt{243}[/tex] = [tex]\sqrt{ 3 x 3 x 3 x 3 x 3 }[/tex] = [tex]\sqrt[9]{3}[/tex]

Answer:

$825.60

Step-by-step explanation:

Since the price of it is $960.00, it means that it's 100%.

100% = 960

1% = 960 ÷ 100 = 9.6

14% = 9.6 x 14 = 134.40

Since they asked for after the discount, deduct the price of the discount with the original price.

Mountain bike after 14% discount =

960 - 134.40 = 825.60

Answer:

hello! i just did this problem and the answer is 12.2%

Step-by-step explanation:

first we need to add all of the swans together, then from there you take the amount of mute swans and divide it by the sum of all the swans! finally, multiply by 100 to convert into a percent and round it to 12.2%

hope this helped plz give me brainliest! <3

The solution is 12.2 %

The percentage of mute swans is given by the equation A = 12.2 %

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the percentage of mute swans be represented as A

Now , the equation will be

Let the total number of swans be S

The number of mute swans = 5  swans

The number of Trumpeter swans = 34 swans

The number of Tundra swans = 2 swans

So , the total number of swans S = 5 + 34 + 2 = 41 swans

And , the percentage of mute swans A = ( number of mute swans / total number of swans S ) x 100

Substituting the values in the equation , we get

The percentage of mute swans A = ( 5/41 ) x 100

On simplifying the equation , we get

The percentage of mute swans A = 0.1219 x 100

The percentage of mute swans A = 12.19

The percentage of mute swans A = 12.2 %

Therefore , the value of A is 12.2 %

Hence , the percentage is 12.2 %

Answer:

0.015625

Step-by-step explanation:

The probability that Nick wins at least once is 2.5

"Probability is finding out the possibilities of the occurrence of an event."

"P(A) = n(A) / n(S)

where, n(A) is the number of favorable outcomes of an event A

n(S) is the total number of outcomes for an experiment"

"It is a number that can be expressed as a fraction of 100."

For given example,

Nick has a 25 percent chance of winning on any individual.

This means, his chances of winning on any individual spin are 0.25

Individual spins are independent and Nick decides to play the game 10 times.

So the probability that Nick wins at least once is 10 × 0.25 = 2.5

Therefore, the probability that Nick wins at least once is 2.5

Step-by-step explanation:

Just did the math. Convert 4 1/3 to 0/6. So 1 times 2 is 2, and 3 times 2 is 6. Which would give you 4 2/6 which has the same denominator as 1 5/6.

Answer:

b = 16

Step-by-step explanation:

× stands for varies

a × √bc,

a = k√bc,

when a = 24, b = 8, c= 2

a = k√bc

24 = k√8•2

24 = k√16

24 = 4k

dividing both sides by 4

k = 24/4

k = 6

a = 6√bc (standard equation)

find b when a = 48 and c = 4

a = 6√bc

48 = 6√b•4

dividing both sides by 6

48/6 = √b•4

8 = √b•4

squaring both sides

8^2 = b•4

64 = b•4

b = 64/4

b= 16.

Thrrefore when a = 48, c = 4, b = 16.
