Answer 1
when finding the bottom numbers, divide the top number by 3

when finding the top numbers,
multiply the bottom number by 3

21 / 3 = 7
12 X 3 = 36
20 X 3 = 60
90 / 3 = 30

answer: c
Answer 2

Answer:

The answer is c! 7,36,60,30

Step-by-step explanation:

To answer this equation you have   to find  a number that fits the description of what is required. It may seem difficult but it's not  first off it's trial and error  you have to find the right equation for every given number. For example,  what makes 15  equal 5  true? To make the equation true you have to do 15 divided by 3 equals 5  now we take the / 3 and apply them to all the other numbers  so 21 / 3 is  7 ,  36  divided by 3 is 12  hi, 60 / 3 is 20 ,  90 /3 is 30. If you have any other question like this all you have to do is trial and error with a number to make the equation true hopefully that helps! (B.t.w / symbol means divided by)

Gia receives an allowance of $2 a week and already has $20 in savings. Michael receives an allowance of $3 a week and already has $5 in savings. Gia and Michael both save their entire allowance. After how many weeks, will Gia and Michael have the same amount in savings? How much money will they have?

Answers

Answer:

After 15 weeks, Gia and Micheal will both have $50 in savings.

Step-by-step explanation:

For Gia:

We start at $20 since she already has $20 in savings, we will add that to how much Gia will receive in 15 weeks.

Gia receives $2 a week and therefore in 15 weeks she will have $50.

= 2x15 = $30

= 30+20 =  $50

For Micheal:

We start at $5 since he already has $5 in savings, we will add that to how much Micheal will receive in 15 weeks.

Micheal receives $3 a week and therefore in 15 weeks he will receive $50

= 3x15 = $45

= 5+45 = $50

HELP PLEASE ILL GIVE 10 POINTS

Answers

Answer:

The answer would be 150 degrees.

Step-by-step explanation:

When looking at the problem you can see that you have two parallel lines and a transversal. Since the two lines are parallel, this allows alternate interior angles to form, i.e. <A and <B.

Since angle A and B are alternate interior angles, you can now set the two equal to each other.

So, in order to find out what x equals, you have to set the two equations equal to each other.

8x-10=3x+90

Next, solve the new equation.

8x-10=3x+90

Add 10 to both sides.

8x=3x+100

Subtract 3x from both sides.

5x=100

Divide both sides by 5 and you'll get your answer.

x=20

Now that you know what x equals, you can substitute it into the equation for B.

<B= 3(20)+90

60+90= 150

<B=150 degrees

That gives you your answer of <B = 150 degrees.

To check your work you can also substitute x into the equation for <A.

<A= 8(20)-10

160-10= 150

<A=150 degrees.

Therefore, you have just proved that the answer is 150 degrees.

Answer:

Step-by-step explanation:

Pythag Theorem is Leg² + Leg²= Hypotenuse²

So I set it up as: x² + 9²=15²

Then solved and got: x² + 81 =225

Then I subtracted 81 on both sides and got: x² = 144

Then squareroot each side to undo the x² and got x=12

The formula for the pythagorean theorem is a^2 + b^2 = c^2, or in this case, leg^2 + leg^2 = hypotenuse^2. After inserting the values into the equation, you get x^2 + 9^2 = 15^2. The next step is to find the value of x, and to do so, you must evaluate the powers (9^2 = 81, 15^2 = 225) and subtract 81 from both sides of the equation. Lastly, take the square root of both sides, and you get the final answer of 12.
