Answer:

12ab  

6x+7y

Step-by-step explanation: hope I helped

Answer:

( a ) 3a ( 4 ) b

= 12ab

( b )Let's simplify step-by-step.

5x + 9y + x − 2y

= 5x + 9y + x + − 2y

Combine Like Terms:

= 5x + 9y + x + −2y

= ( 5x + x ) + ( 9y + −2y )

= 6x + 7y

Answer:

x= −1 /2 y+4

Step-by-step explanation:

Let's solve for x.

2x+y=2(6−2)

Step 1: Add -y to both sides.

2x+y+−y=8+−y

2x=−y+8

Step 2: Divide both sides by 2.

2x /2= −y+8 /2 x= −1 /2 y+4

Answer:

Below in bold.

Step-by-step explanation:

The total sum of the numbers in A is 124 and the sum of the numbers in B = 56

Let x be the number passed from A to B, then from the given information:

124 - x = 56 + x + 20

124 - 56 - 20 = 2x

48 = 2x

x = 24.

a) So the number passed is 24.

b) Sum of numbers in B = 56 + 24 = 80.

c) Let pencil cost x then pen will cost 1.1 - x.

Now the pen costs 1 pound more than the pencil

so  1.1 - x - x = 1

-2x = -0.1

x = 0.05.

So the pen costs 1.1 - 0.05 = £1.05.

Answer:

409 = 223 + z

z = 186

Step-by-step explanation:

We know Tyler is 223 - z or z + 223

409 = 223 + z

409 = z + 223

409 - 223 = z + 223 - 223

186 = z + 223 - 223

z = 186

Step-by-step explanation:

The angles are vertical because they are opposite to each other

75 = 4x -25 vertical angles

100 = 4x

x= 25° Algebra

Answer:

X = 25 degrees

Definitions:

Vertical: Opposite angles/angles that share a common side.

Adjacent: Congruent meaning same measure.

Step-by-step explanation:

This equation would be vertical because they are opposite from eachother:

Our equation would look like this:

75 = 4x - 25

Then add 75 and 25 to get 100:

75 + 25 = 100

Now our equation would look like this:

100 = 4x

Lastly, divide 100 with 4:

100 ÷ 4 = 100

Side note: 25 x 4 = 100

Your answer would be x = 25 degrees.

Answer:

In order to be considered a language, a system of communication must have vocabulary, grammar, syntax, and people who use and understand it. Mathematics meets this definition of a language. Linguists who don't consider math a language cite its use as a written rather than spoken form of communication

Answer:

-45x - 18

Step-by-step explanation:

distributive property

Answer:

x = 18/45 (or, in a decimal, 0.4). Someone correct me if I'm wrong. :)

Step-by-step explanation:

We have to use the distributive property here. That means that you multiply -5x by 9 and -2 by 9. So...

9*-5x = -45x

9*-2 = -18

-45x = -18

Now, divide both sides by 45...

-45x/45 = -18/45

x = 18/45 should be the answer.

Answer:

228,710.84 frws

Step-by-step explanation:

A trader banks 250000frws at 9%per year compound interest rate calculated every 4 months. find the amount in the bank at the start of the year?

The above question is asking us to find the Principal. The formula is given as:

P = A / (1 + r/n)^nt

A = Amount after time t = 250000

r = Interest rate = 9%

n = Compounding frequency = 4

t = time = 1 year

First, convert R as a percent to r as a decimal

r = R/100

r = 9/100

r = 0.09 per year,

Then, solve the equation for P

P = A / (1 + r/n)^nt

P = 250,000.00 / (1 + 0.09/4)^(4)(1)

P = 250,000.00 / (1 + 0.0225)^(4)

P = $228,710.84

The bank started with 228,710.84frws

Answer: The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.

Step-by-step explanation:

The slope of a perpendicular line will be m = 3/2. To find the perpendicular gradient take the negative inverse of the original gradient.

By 'negative inverse' I mean change the sign and switch the numerator and denominator (the top and bottom of the fraction).

The original gradient there is m = - 2/3. Remember the line equation: y = mx + c.

To gain the perpendicular gradient change the - to +, move the 3 to the top and the 2 to the bottom. Now m = + 3 / 2 = 3/2

Noah is right because 75% of $10 would be 7.5 and 25% of $30 is 7.5. This would mean that they both have equal amounts of money
