Answer:
maybe number 2
Step-by-step explanation:
because if 2+k=18 then there is no other k there and where did the additional 2 come from ?and 2k=18 then value of k is 9 + there is balance.I may be wrong correct me but i think it is no.2
Answer:
a. 3x=5 Positive Solution
Reasoning: You're working with only positives
b. 5z+7=3 Negative Solution
Reasoning: If you carry the 7 over the non-coefficient numbers will be negative thus making your answer negative
c. 7-5w=3 Positive Solution
Reasoning: both the coefficients and the non coefficients will be negative if solved and thus will result in the negatives becoming positive when dividing the 5w
d. 4a=9 Positive
Reasoning: The first step would be to divide the 9 by 4 and the resulting number would be positive
e. y=y+1 Negative Solution (No solution)
Reasoning: y can never equal itself with changing. Thats like saying 0 is 1. This has no solution but based on the rules this is negative solution
6% of $95 = $5.70
multiply $5.70 by 11 years = $62.70 <— interest gained over 11 years
multiply $18 by 11 years = $198 <— total added over 11 years
add $95 + $62.70 + $198 = $355.70
there will be a total of $355.70 in your account after 11 years
Answer:
x = -4/5
Step-by-step explanation:
subtract 25/6 from both sides
getting
5x = -20/5
divide by 5
x = -20/5 ÷ 5 or -20/5 × 1/5 = -20/25 = -4/5
Answer: (-4s-1)*(-8) + (-4)*(-8s+7)
You have the right idea, but you swapped the items in the wrong order. Meaning that you applied the derivative to the wrong pieces as shown in the order above. It seems you have to follow this specific order for the computer to accept the answer.
