Answer:
x+8/9
y= -1/3
Step-by-step explanation:
3x+2(-3+3x) =2

9x-6=2
9x=8
x= 8/9
now plug x into the y equation
y= -3 +3(8/9)
y= -3 +8/3
y= -9/3+8/3
y= -1/3

Step-by-step explanation:
Factor completely. a^n+a^n+1
The requried factor of the given expression aⁿ +aⁿ⁺¹ is given as aⁿ and (1 + a)
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
Here,
Given expression,
= aⁿ +aⁿ⁺¹
In order to factor the above expression we are using the property,
x² = x¹ (x¹)
So,
= aⁿ + a.aⁿ
Now, taking aⁿ common,
= aⁿ(1 + a)
So, aⁿ and (1 + a) are the requried factors.
Thus, the requried factor of the given expression aⁿ +aⁿ⁺¹ is given as aⁿ and (1 + a)

Answer:
30
Step-by-step explanation:
Answer:
1.) B.) 30
2.) D.) 2.38
Step-by-step explanation:
1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.
2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:
Start: Year 1: Year 2: Year 3: Year 4:
$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

How much solutions does this equation have?
2x+y=3
2y=-4x+6
pls answer,, show ur work, have a great day :)) !!
Answer:
All solutions or infinite.
Step-by-step explanation:
Turn 2y = -4x + 6 into standard form - divide by 2
Y = -2x + 3
2x + y = 3
Substitute the y equation in for y.
2x - 2x + 3 = 3
The x variables cancel out.
3 = 3
Which is true so it means all solutions.
Hope this helps.

The students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining. The table shows the number of carrots remaining after different amounts of time. Which snack did the students eat at a faster rate? Explain.
Answer:
Grapes
Step-by-step explanation:
The rate of change for the grapes was -12 grapes per minute.
To calculate the rate of change for the carrots, use the slope formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex]. In this case, m is the rate of change, time is x, and the carrots remaining is y.
[tex]m = \frac{118-136}{8-6} = \frac{-18}{2} = -9[/tex]
The decrease in grapes was much greater than the decrease in carrots, so therfore the students ate the grapes at a faster rate.
If the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that, the students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining.
Grapes were changing at a pace of -12 grapes per minute. Use the slope formula to get the rate of change for the carrots.
m=118-136/8-6
m=-18/2
m=-9
The students consumed the grapes more quickly because the decline in grapes was significantly larger than the decline in carrots.
Thus, the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beans of 5 to 2. If he wants to use a total of 126 cans, how many cans of green beans should he use?
please help me lol
Answer:
90 pumpkin and 36 green beans
Step-by-step explanation:
Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.
Answer:
9 cans
Step-by-step explanation:
126/7=18
18/2=9
so 9 is the answer

Help please. You have to use distributive property to solve.
Answer:
m = 21
Step-by-step explanation:
12 = 3(m - 17)
12 = 3m - 51 (Found using the distributive property)
63 = 3m (Found by adding 51 to both sides)
21 = m (Found by dividing both sides by 3)

Kai calculates that he spends 15% of a
school day in science class. If he spends
75 minutes in science class, how many
minutes does Kai spend in school?
Answer-
Kai spends 8 hours 20 minutes in school.
Solution-
Let us assume, Kai spends x minutes in school.
Kai calculates that he spends 15% of a school day in science class and that is 75 minutes, i.e
\Rightarrow x\times \dfrac{15}{100}=75⇒x×
100
15
=75
\Rightarrow x=75\times \dfrac{100}{15}⇒x=75×
15
100
\Rightarrow x=\dfrac{7500}{15}⇒x=
15
7500
\Rightarrow x=500\ \text{minutes}⇒x=500 minutes
\Rightarrow x=\dfrac{500}{60}\ \text{hours}⇒x=
60
500
hours
\Rightarrow x=\dfrac{25}{3}\ \text{hours}⇒x=
3
25
hours
\Rightarrow x=8\dfrac{1}{3}\ \text{hours}⇒x=8
3
1
hours
Therefore, Kai spends 8 hours 20 minutes in school.

a tree that is 13 feet tall is growing at a rate of 4 feet each year. A different tree that is 27 feet tall is growing at a rate of 1/2 feet each year. At this rate, when will the trees be the same height? What will the height of the trees be?
(Also I need help before 3 pm it’s 1:21 pm btw) PLEASE HELP
Answer:
Step-by-step explanation:
After t years,
the first tree will be 13+4t feet tall
the second tree will be 27+½t feet tall.
When they are the same height,
13+4t = 27+½t
subtract ½t from both sides
13+3½t = 27
subtract 13 from both sides
3½t = 14
divide both sides by 3½
t = 14÷(3½) = 14÷(7/2) = 14× (2/7) = 4
The trees will be the same height in 4 years.

The price of gasoline rose from $2.40 to $2.76 in one month. By what percent did the gas price rise?
Answer: 15%
Reason: I wrote it down hopes it helps!!
The percent of increase of any quantity is the ratio of the change in the value of that quantity to the initial value of the quantity. The gas price rose by 15%.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The initial price of gasoline = $2.40
The final price of gasoline = $2.76
Thus, change in the price = $2.76 - $2.40
= $0.36
Now, the percentage increase of price is given by,
(change in the price ÷ initial price) × 100
= (0.36 ÷ 2.40) × 100
= (3 / 20) × 100
= 15
Hence, the percent increase in the price is given by 15%.
