2(3x-2y) + 3(x-3y)

Answers

Answer 1

Answer:

9x - 13y

Step-by-step explanation:

2(3x - 2y) + 3(x - 3y)

Use distributive law a(b + c) = ab + ac

⇒ 2·3x - 2·2y + 3·x - 3·3y

⇒ 6x - 4y + 3x - 9y

Gather like terms:

⇒ 6x + 3x - 4y - 9y

Combine like terms:

⇒ 9x - 13y

Answers

1800 cm: 20 m in its simplest form is 9cm : 10 cm

What is ratio?

Ratio says how much of one thing there is compared to another thing. Ratio compares value.

Therefore, let's make the unit the same.

0.01 m = 1 cm

20m =

length = 20 / 0.01

length = 2000 cm

Therefore, the ratio is as follows:

1800 cm : 2000 cm

Let's write it in it simplest form.

1800 / 2000 = 9 / 10

Therefore, the simplest form is 9 cm : 10 cm

Find a value for Y and give a reason for your answer

Answers

Step-by-step explanation:

inscribed angles subtended by the same arc are equal.

the central angle of a circle is twice any inscribed angle subtended by the same arc.

the first statement tells us that the 53° angle as well as y stay the same size no matter where on their arcs (between the 2 points connected to O) they would be. so, we don't need to bother with any line lengths.

the 2nd statement tells us that x = 2×53 = 106°. the 53° and x angles refer to the short arc on the right of the 2 points connected to O.

and y and x refer to the larger arc on the left of the 2 line connected to O. that means according to the second statement : 360-x (the big angle around O) = 2y

so,

360 - 106 = 2y

254 = 2y

y = 127°

Benjamin has 3 dimes and 4 nickels. What percent of a dollar does he have?

Answers

Answer:

50%

Step-by-step explanation:

Hope this helped

Maybe mark brainiest

Dime = 10 cents

Nickel = 5 cents

Total value of coins = 3(10) + 4(5) = 30 + 20 = 50

To find the percent, first create a fraction. The fraction will be the amount of money that Benjamin has over the total (one dollar).

50 / 100 = 5 / 10 = 0.5

0.5 x 100 = 50

50%

Answer: 50% of a dollar

Set up the problem as an equation where X is years: 14+X = (56+X)/2 Solve for X 14+X = 28 + 0.5*(X) subtract 14 from both sides: X = 14 + 0.5*(X) subtract 0.5*(X) from both sides: 0.5*(X) = 14 Solve for X by dividing both sides by 0.5: X = 28
