<em><u>Answer 1: 177 – 77 = 100 </u></em>
<em><u>Answer 2: (7+7) * (7 + (1/7)) = 100</u></em>
Answer:
3). 1.21
4). 0.57
Step-by-step explanation:
Quarter = 25 cents
Nickel = 5 cents
Penny = 1 cent
You have to find the discriminat b^2 -4ac
If it is > 0, the function has two real solutions
if it is = 0, the function has one real solution
if it is <0, the function has no real solution
6^2 - 4(7)(3) = 36 - 84 = - 48
Answer c. no solution
So first you have to multiply 21 by .1 to figure out ten percent
you then get 2.1
you add 21 and 2.1 together and get 23.1
then since you have 3 people you divide by 3 and get 7.7
therefor 7.7 is your answer
