Answer:Find out the expressions for the number of sweets sue and tony have now .
To proof
As given
Sue has 18 sweets. tony has 18 sweets.sue gives tony x sweets
thus
sue sweets = 18 - x
Tony sweets = 18 + x
As given
Sue then eats 5 sweets. Tony then eats half of his sweets
sue sweets becomes = 18 -5 -x
= 13 - x
Hence proved
Step-by-step explanation:
Combine like terms. 7x-3x=4x and -5-(-2)=-3. The answer is D. 4x-3
<span>2x^2 - 6x - 36= 2*(x^2 - 3x -18)
Lets solve this now: </span>x^2 - 3x -18=0
or -3
x^2 - 3x -18=0
(x+3)(x-6)=0
So the solution is
2(x+3)(x-6)
We can drop a perpendicular from X to PQ at A, and from Y to RS at B. Then XA = YB = 48/10 = 24/5. We can also draw a line through X parallel to BY meeting the line through Y parallel to RS at C.
Then XC = 24/5 + 24/5 + 10 = 98/5 and YC = 10 - 34/5 = 16/5, so XY^2 = XC^2 + YC^2 = (98/5)^2 + (16/5)^2 = 1972/5.
The answer to this would be C because you can multiply everything by 3 and still have a consistent-dependent system.
