Answer:
Step-by-step explanation: if there are 500 pieces of paper and the entire stack is 1.875 inches tall, you devide the total height by 500. I know Deigo is wrong because you can easily reverse check his work by multiplying 0.015 by the total number of papers 500 you will get 7.5 which is not the height of the stack
1.875/500=0.00375
each piece of paper is 0.00375
It should be A. You would keep the 5, and the exponent should be 4+8, which is 12.
The answer is 52.80 because the tip is $8.80 and 44.00+8.80=52.80
Answer:
D. b + a = c
Step-by-step explanation:
c – a = b
Add a to both sides.
c = b + a
b + a = c
Answer: D. b + a = c
To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.
jk=ac and j+k=b
The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...
2k^2-5k-18=0
2k^2+4k-9k-18=0
2k(k+2)-9(k+2)=0
(2k-9)(k+2)=0
so k=-2 and 9/2
k=(-2, 4.5)
