todd = 8 + 9

sally = 18 + 7

Just keep adding until they have the same amount if they ever do.

todd 17 26 35 44 53

sally 25 32 39 46 53


so it took them  5 mouths and they both have 53  CD's

Help me pleasee (10 points)
Montano1993 [528]

Answer:

B

Step-by-step explanation:

Givens

a^2 + b^2 = c^2

a = 4x

b = x + 2

c = 3x + 4

Solution

(4x)^2 + (x + 2)^2 = (3x + 4)^3                  Remove all the brackets.

16x^2 + x^2 + 4x + 4 = 9x^2 + 24x + 16  Collect like terms on the left

17x^2 + 4x + 4 = 9x^2 + 24x + 16            Subtract the terms on the right

8x^2 - 20x - 12 = 0

This factors into

(4x - 12)(2x + 1)

There are 2 answers

4x - 12 = 0

4x = 12

x = 12/4

x = 3

or

2x + 1 = 0

2x = - 1

x = - 1/2

You have to look at x = -1/2 carefully. The problem is that 4x = 4*(-1/2) = - 2 which is not possible in Euclidean Geometry.

So the only answer is x = 3

steposvetlana [31]

Answer:

x=1 y=-5

Step-by-step explanation:

7(5x-2y=15) --->      35x-14y=105

2(7x+7y=-28) -->  + <u>14x+14y=-56</u>

                               49x=49  --->x=1

5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5

How many grams are 2.7x10-^4 grams
andrew-mc [135]

Answer:

0,00027 grams!

Step-by-step explanation:

This is a scientific notation problem.

When a number is followed by a 10^{-1}, it means that said number has one zero at the beginning.

In this case, the number is followed by 10^{-4}, so that means that 2.7 has four zeros at the beginning. So, 2.7x10^{-4} grams is equal to 0,00027 grams! (always the comma goes after the first zero).
