Explanation:

"Like" radicals can be added and subtracted in the same way any like terms can be combined. It can be helpful to simplify the radical as much as possible so that it can be seen whether the radicals are "like" or not.

Examples:

  √2 +√3 . . . . cannot be combined

  √2 +√8 = √2 +2√2 = 3√2 . . . . the simplified radicals can be combined

Answer:

0.2

Step-by-step explanation:

When you have a decimal problem you add a 0 before the number. But if its a fraction ike 4 5/8 the decimal would be 4.58.

Answer:

9 percent

Step-by-step explanation:

Answer:

3%

Step-by-step explanation:

1st Method: Increase Formula = (Last value-first value)/(first value)

Increase = (309-300)/300 = 9/300 = 3/100

= 0.03 or 3%

2nd Method: 309/300 = 103/100 = 1.03 (increase over 1 is 0.03 = 3%

Answer:

the answer is six and two

Answer:

Non-linear

Step-by-step explanation:

Not consistently increasing

Answer:

x=-10

Step-by-step explanation:

[tex]2(x+3)=x-4[/tex]

distributive property on left side:

[tex]2x+6=x-4[/tex]

subtract x from both sides

[tex]x+6=-4[/tex]

subtract 6 from both sides

[tex]x=-10[/tex]

Answer:

-10

Step-by-step explanation:

2(x+3)=x-4

Distribute (multiply everything in parenthesis):

2x+6=x-4

Subtract -x from both sides

X+6=-4

Subtract 6 from from both sides:

X=-10

Answer:

m∠B = 63°

AB = 26.4

AC = 23.6

Step-by-step explanation:

m∠B = 90 - 27 = 63°

Sin 27 = 12/AB

AB (sin 27) = 12

AB = 12/sin 27 = 26.4

Tan 27 = 12/AC

AC (tan 27) = 12

AC = 12/tan 27 = 23.6

Answer:

y = -3x - 2

Step-by-step explanation:

Y = Mx + b

[slope = m, y-intercept = b]

plug in values:

y = -3x - 2

(P.S. - I saw your last question, sorry people aren't answering. I'll try my best to answer your questions if you have any others :) )

Without the y provided alongside the slope and y intercept, this problem can not be solved.

Answer:

-5m

Step-by-step explanation:

6m-12m-4m+5m

-6m+1m

=-5m

Answer:

-56

Step-by-step explanation:

That is because the 56 is below sea level, not above it, so it would be negative 56

Hope that helps!

-56ft

Since it is BELOW sea level it would be considered a negative number. If it were ABOVE sea level then it would be a positive number. Another way to think about this:

Above Sea Level = +

Below Sea Level = -

Hope this helps and have a nice day.

Answer: $0.50 per pound of bananas

Step-by-step explanation:

Take the total price of five pounds of bananas ($2.50) and divide them

2.50/5

You will get

$0.50

Answer:

-10

Step-by-step explanation:

Note that the points plotted on the line is by 2 (essentially, each line signifies 2).

The blue point is on the 5th line from the 0. 5 x -2 = -10

-10 is your answer.

Step-by-step explanation: The price of3.8 pounds of almonds=$39.90 thus we can write Hence the price of almonds is $10.50 per pounds.

AWNSERS:$10.50

Answer:

Step-by-step explanation: 39.90 x 3.8 = 151.62

Answer:

31 1/2 ft^3

Step-by-step explanation:

volume = length x breadth x height

1/2 x 6 x 10 1/2

1/2 x 6 x 21/2 = 63/2 = 31 1/2 feet³

Answer: 5X +40 = 100

Step-by-step explanation:

Answer:

1200 feet

Step-by-step explanation:

A scale is a representative faction which can be used to either increase or decrease the size or dimensions of an object.

scale = [tex]\frac{model height}{actual height}[/tex]

[tex]\frac{2inches}{160 feet}[/tex] = [tex]\frac{15 inches}{actual height}[/tex]

actual height = [tex]\frac{15 *160}{2}[/tex]

                      = [tex]\frac{2400feet}{2}[/tex]

                      = 1200

actual height = 1200 feet

The actual height of the skyscraper is 1200 feet.

Answer:

1065. 1 * 10^3

Step-by-step explanation:

Answer:

Initial value is (0 , 24) or just y = 24

Step-by-step explanation:

Initial value of a linear function is the y intercept

y = -3x + 24

x = 0, y = 24

Answer:

20

Step-by-step explanation:

Use the distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\d = \sqrt{(-7 - 5)^2 + (-7 - 9)^2}\\d = \sqrt{(-12)^2 + (-16)^2}\\d = \sqrt{144 + 256}\\d = \sqrt{400} = 20[/tex]

The distance between the points (5,9) and (-7,-7) will be 20 units.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D² = (x - p)² + (y - q)²  

The points are given below.

(5,9) and (-7,-7)

Then the distance between the points will be

D² = (5 + 7)² + (9 + 7)²  

D² = 12² + 16²  

D² = 144 + 256

D² = 400

D = 20 units

Answer: The answer is B

Answer:

x=2.142137

Step-by-step explanation:

Solve Exponent.

12x=205

log(12x)=log(205)(Take log of both sides)

x*(log(12))=log(205)

x=

log(205)

log(12)

x=2.142137

Answer:

Step-by-step explanation:

[tex]\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{m}*a^{n}=a^{m+n}\\\\\frac{125t^{-4}}{5^{-3}}*625*t^{-8}\\\\=\frac{5^{3}t^{-4}}{5^{-3}}*5^{4}*t^{-8}\\\\=5^{3-[-3]+4}*t^{-4-8}\\\\=5^{3+3+4}t^{-12}\\\\=5^{10}t^{-12}\\\\=\frac{5^{10}}{t^{12}}[/tex]

Answer:

-10%

Step-by-step explanation:

precent change = 135 - 150

(divide both sides by 150)

precent change = -0.1

(multiply both sides by 100 so change to precent)

precent change = -10%

Answer:

Answer:

The numerical value is 7.

Step-by-step explanation:

If 4 x is 3 y, then 8 x must be 3 x 2, which is obviously 6.

6y + y = 7y
