Answer:
40
112
2n^2 + 2n C
Step-by-step explanation:
a)The correct formula is 2n^2 + 2n
So for n =4, the answer is
2*4^2 + 2*4
2*16 + 8
32 + 8
40
b) For the seventh answer you get
2 * 7^2 + 2*7
2*49 + 14
98 + 14
112
c) The correct formula to use is
2n^2 + 2n See diagrams for the number of matchsticks to be used.
n 2n^2 + 2n
1 2*1^2 + 2*1
1 2 + 2
1 4
2 2*2^2 + 2*2
2 2* 4 + 4
2 8 + 4
2 12
3 2*3^2 + 2*3
3 18 + 6
3 24
What an extremely interesting sequence. I'll bet not one person in 100 could get this without the match stick diagrams. I'm sorry I didn't read the question more carefully.

Answer:
[tex]\Large\boxed{\text{The amount of money changes by \$50 per week.}}[/tex]
[tex]\Large\boxed{s(t) = 70+50t}[/tex]
Step-by-step explanation:
We can create a function based on this scenario.
We know that you start with $70. This would be a constant. So, we already know that our function will contain +70.
If we earn $50 a week, we know that we can create an expression here to find how much we make based on how many weeks we spend, assuming t represents the amount of weeks we spent.
[tex]50t[/tex]
We can add this to our original constant of 70.
[tex]70+50t[/tex]
Since the output will be a function based on how many weeks we spend, we can make it equal to s(t).
[tex]s(t) = 70+50t[/tex]
The slope here is 50, meaning that every week we earn 50 dollars more.
This means the amount of money changes by 50$ per week.

Michelle is a server in a restaurant. On a weekend night, Michelle earned $4 an hour and $65 in tips. She made a total of $93. Write and solve an equation to determine how many hours she worked. On Monday, Ken spent half of his money on a new game. The next day he earned $12 mowing lawns. He now has $32. How much money did Ken have before bought the game? I need the equation too.
Answers
Answer:
first question: Michelle worked for 7 hours
second question: Ken had $40 before buying the game
Step-by-step explanation:
4x + 65 = 93
4x = 28, x = 7
Michelle worked for 7 hours
Ken 1/2x + 12 = 32
1/2x = 20
x = 20. 20*2 = $40, ken has $40 before buying the game.

Answer:
-1.6r + 1.8
Step-by-step explanation:
-1.6 (r+2) +5
^ the -1.6 can be distributed to the (r+2) because it's basically multiplying
that becomes --> -1.6r + -3.2 + 5
Now the -3.2 and 5 are like terms so they can be solved together
-> -3.2 + 5 = 1.8
Now, -1.6r and 1.8 are not like terms because 1.8 does not have an r attached to it so you cannot do nothing from there
your answer becomes = -1.6r + 1.8

Erin weighs 135 pounds and is gaining ½ pound each week. Miranda weighs 143 pounds and is losing ¼ pound each week. Write an equation that could be used to determine x, the number of weeks that it will take until the two girls weigh the same amount?
Answers
Answer:
10.66 weeksStep-by-step explanation:
Number of weeks is x
135 + 1/2x = 143 - 1/4x1/2x + 1/4x = 143 - 1353/4x = 8x = 32/3 = 10.66 weeksAnswer:
[tex]135+\frac{1}{2}x=143-\frac{1}{4}x[/tex]
Step-by-step explanation:
Let E represent Erin’s weight, and let M reprevent Miranda’s weight.
And let x represent the amount of week that passes.
Eric is currently 135 pounds. However, she is gaining 1/2 pounds per week x.
Hence, we can write the following equation:
[tex]D=135+\frac{1}{2}x[/tex]
Miranda currently weights 143 pounts. However, she is losing 1/4 pounds per week x.
Since she is losing weight, 1/4 is negative. Hence:
[tex]M=143-\frac{1}{4}x[/tex]
When the two girls weigh the same, D=M. Thus:
[tex]D=M[/tex]
Substitute them for their respective equations to acquire:
[tex]135+\frac{1}{2}x=143-\frac{1}{4}x[/tex]
Notes:
To solve, first eliminate the fractions by multiplying everything by 4. This yields:
[tex]540+2x=572-x[/tex]
Add x to both sides. Subtract 540 from both sides:
[tex]3x=32[/tex]
Divide both sides by 3:
[tex]x=32/3\approx10.67[/tex]
Hence, it will take about 11 weeks for the girls to weigh the same.
