Answer:
Change = (d2 -d1)/d1 x 100
Change = (20-16) / 16 x 100 = 25%
Step-by-step explanation:
The answer is D.
You cannot factorise it as there are two different terms being squared with the middle term containing both. Also, if you expand any of the brackets in the questions you will not get the original equation so non of them are right so it has to be D. :)
Answer:
Kameron has 5 quarters in his wallet
Step-by-step explanation:
Let
x----> the number of nickels
y----> the number of quarters
remember that
1 nickel=$0.05
1 quarter=$0.25
we know that
x=3y -----> equation A
0.05x+0.25y=2
Multiply by 100 both sides
5x+25y=200
Simplify
x+5y=40 -----> equation B
Substitute equation A in equation B
(3y)+5y=40
8y=40
y=5 quarters
x=3(5)=15 nickels
Answer:
5/12
Step-by-step explanation:
5x - 12y = 24
~Subtract 5x to both sides
-12y = 24 - 5x
~Divide -12 to everything
y = -2 + 5/12x
~Reorder
y = 5/12x - 2
Slope is represent by "m" in slope intercept form [ y = mx + b ]. As we can see m = 5/12 from the given information.
Best of Luck!
