In total there are 32 keys.
There 24 silver and copper keys so the probability of one being drawn is 24/32
Now just simplify
24/32 = 12/16 = 6/8 = 3/4
Answer:
Option D: 3x2 + 2x - 1
Step-by-step explanation:
Given that:
=(5x2 - 5x + 3
)- (2x2 +7x- 4)
As we have to subtract them so by simplifying:
"-" sign will alter all signs in the bracket
= 5x2 - 5x + 3 - 2x2 + 7x - 4
Now by adding same terms
= 5x2 - 2x2 - 5x + 7x + 3 -4
= 3x2 + 2x - 1
i hope it will help you!
We have the similar triangles. Therefore the lengths of the sides are in proportion:

Answer: No they don't because there is not way 1/3 can be multiplied by a number to get 2/9 and there is no way 2/9 can be divide by any number to get 1/3.
Step-by-step explanation:
To get rid of the 2/5 next to the g, multiply both sides by the RECIPROCAL of 2/5, which would be 5/2.
The answer is g=15/10, which simplifies to g=1 5/10 and then further simplifies (wow so much simplifying) to get g=1 1/2.
