What is the simplest form of

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

Granny is 56 years old, and her granddaughter is 14. In how many years from now will the grandma be twice as old as the granddaughter?

a) 28
b) 23
c) 10
d) 25

HELPP​

Answers

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

So the answer is a) 28

Answer:

8.0 * 10^4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

(ii) Express 1800 cm: 20 m in its simplest form.

HELPP

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
