Answer:
6 - 2 y
Step-by-step explanation:
2 ( 3 - y )
First you multiply 2 x 3 which will equal ,6.
2 x 3 = 6
Then you multiply the 2 and y which will then equal, 2y.
2 x y = 2 y
Therefore, using distributive property the answer would be,
6 - 2 y
Answer:
6 - 2y
Step-by-step explanation:
Using distributive property to rewrite,
2(3 - y) = 2 × 3 + 2(-y)
Multiply
6 + 2(-y)
= 6 - 2y

Answer:
4^7
Step-by-step explanation:
4^5 × 4^9/4^7
When you’re multiplying exponents with the same bases, add powers together, so...
4^5 × 4^9 = 4^14
= 4^14/4^7
When you're dividing exponents with the same bases, subtract powers from each other, so...
4^14 - 4^7 = 4^7
Therefore, 4^7 is your answer! :)
What is the perimeter of the actual garden?
Answer:
62.5 cm
Step-by-step explanation:
8.5 × 2.5 = 21.25 cm
4 × 2.5 = 10 cm
(10 cm × 2) + (21.25 cm × 2) = 62.5
-Therefore, 62.5 cm as the perimeter is the correct answer.

Maria currently has 465 dollars in her account. She withdrew money for $250 and $175. If she spends $45 to put gas in her car, How much money will Maria have in her account?
Answer:
40$
Step-by-step explanation:
if maria has 465$ in her account and she withdrew 250$ makes 215 but it also says she withdrew 175 so 215 subtract 175 makes 40 dollars if she uses 45 dollars to fill her car up she still only has 40 dollars i hope this helps
Answer: $40
Step-by-step explanation: If Maria has 465 dollars and withdraws takes out subtracts $250 she has $215 after that she takes out or subtracts $175 so than she has $40. I think the answer is $40 but I am not so good at math so I'm not sure

you are taking a science course in which there will be 5 tests. each worth 100 points, you have scores of 91, 94, 97, and 86 on the first 4 tests. you must make a total of 450 in order to get an A in the course. set up an inequality and solve it to find the sey of possible test scores that will give you an A.
9 + 94 + 97 + 86 + x ≥ 450
368 + x ≥ 450
368 - 368 + x ≥ 450 - 368
x ≥ 82
Answer:
Step-by-step explanation:
9 + 94 + 97 + 86 + x ≥ 450
368 + x ≥ 450
368 - 368 + x ≥ 450 - 368
x ≥ 82

4x^2y - 2xz + 2xy^2 - yz factoring by grouping
Answer: (2xy-z)(2x+y)
Step-by-step explanation:
In order to factor by grouping, you take the first two and last two terms and find similaritiess by factoring.
First, find out if there is a GCF. In this case, there is none, so we can skip this step.
Next, group (4x^2y-2xz)+(2xy^2-yz). Take out the GCF of the grouped factors separately: 2x(2xy-z)+y(2xy-z). Notice how both of these grouped terms share a common factor.
What you would do is take that and move it to the front. Then, notice how the 2x+y is still remaining. This becomes the 2nd factor.
Therefore, the answer is (2xy-z)(2x+y)

John currently has $500 in his lunch account. He spent $15 each day on lunch. In how many days will John have $245?
Answer:
18 days.
Step-by-step explanation:
Step 1) Building an arithmetic sequence
We can build an arithmetic series with the given information.
The [tex]n[/tex]th term of an arithmetic series is given by the formula [tex]a_n = a_1 + (n - 1)d[/tex] .
[tex]a_1 = 500\\d = -15\\\to a_n = 500 - 15(n - 1) = 515 - 15n[/tex]
Step 2) Finding the n for which a(n) = 245
As this step's title implies, we need to solve the equation [tex]a_n = 245[/tex]:
[tex]515 - 15n = 245 \text{ / Subtract 245}\\515 - 15n - 245 = 245 - 245\\\to 270 - 15n = 0 \text{ / Add 15n}\\270 - 15n + 15n= 0 + 15n\\\to 270 = 15n \text{ / Divide by 15}\\\frac{270}{15} = \frac{15n}{15}\\\to 18 = n[/tex]
John will have $245 in 18 days.
Answer:
17 days
Step-by-step explanation:
Since John starts with $500 and each day, he’ll spend $15 on lunch. This means that:
On his first day, he’ll spend $15.On his second day, he’ll spend another $15 which is total spend of $30 ($15 x 2)On his third day, he’ll spend total of $45 ($15 x 3)Therefore, on his nth day, he’ll spend $15n where n represents the day. The problem can be modeled into an equation of [tex]\displaystyle{500-15n=245}[/tex] since we will be finding how many days it will take to reach $245.
Then solve for n-term which we determines as the day variable:
[tex]\displaystyle{500-15n-245=0}\\\\\displaystyle{255-15n=0}\\\\\displaystyle{255=15n}\\\\\displaystyle{n=17}[/tex]
Therefore, on his 17th day, he’ll have $245. Hence, the answer is 17 days.

"A stack of boxes is 6/5 meters tall. Each box is 3/10 meter tall. How many boxes are in the stack?"
Answer:
[tex]{\Large{ \fbox{ \sf{Four \: Boxes }}}}[/tex]
Step-by-step explanation:
Let x boxes are there such that sum of each box's height results in height of stack of boxes,
the expression will look like this
[tex] \frac{3}{10} \times x = \frac{6}{5} [/tex]
solving for x,
[tex]x = \frac{6 \times 10}{5 \times 3} [/tex]
[tex]x = \cancel{ \frac{60}{15} }[/tex]
[tex]x = 4[/tex]
Answer - There are four boxes.

Algebra gotta be the most hardest math. Help a sister out
How many dogs were in the sample?
Weight of Dogs In the Pet Store
Stem Leaves
0 | 3, 8
1 | 0, 1, 4, 7
2 | 2, 4, 5
3 | 5
4 | 0
0 | 3 = 3 pounds
The mean of the dataset is 3.55
How do determine the mean?
The dataset is given as:
0 | 3, 8
1 | 0, 1, 4, 7,
2 | 2, 4, 5
3 | 5 0
Remove the stems
3, 8
0, 1, 4, 7,
2, 4, 5
5 0
The mean is then calculated as:
Mean = Sum/Count
So, we have:
Mean = (3 + 8 + 0 + 1 + 4 + 7 + 2+ 4 + 5 + 5 + 0)/11
Evaluate
Mean = 3.55
Hence, the mean of the data is 3.55
