Answer:2y+1=y-5.
We move all terms to the left:
2y+1-(y-5.)=0
We add all the numbers together, and all the variables
2y-(y-5)+1=0
We get rid of parentheses
2y-y+5+1=0
We add all the numbers together, and all the variables
y+6=0
We move all terms containing y to the left, all other terms to the right
y=-6

A lion needs to eat at least 15 pounds of food each day. The zoo feeds the lion using canisters that each contain 3 pounds of food. The lion has already consumed 9 pounds of food. How many more canisters x of food does the lion need to eat? Write your answer as an inequality.
Answer:
15 lbs total
1 canister - 3 lbs
lion has already consumed 9 pounds, "3 x 3 canisters of food"
15 - 9 = 6
6/3 = 2
the person needs to feed the lion 2 more canister

The diameter of a cylindrical water tank is 10 ft, and it's height is 11 ft. What is the volume of the tank? Use the value 3.14 for pie, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer:
864.05ft^2Step-by-step explanation:
Step one:
given data
diameter= 10ft
radius = 10/2= 5ft
height = 11ft
Step two:
Required
the volume of the cylinder
The expression for the volume of the cylinder is
v= πr^2h
substituting our given data
v= 3.142*5^2*11
v=3.142*25*11
v=864.05ft^2
A boat is carrying containers that weigh 4000 pounds each.
Use this information to fill in the table. Then plot the ordered pairs given by the table.
Answer:
4 = 16,000
8 = 32,000
10 = 40,000
Step-by-step explanation:
4 x 4 = 16 then add the zeros and then you have 16,000. Same thing with 8. 4 x 8 = 32 then add the zeros. Also goes for 10. 4 x 10 = 40 then add the zeros.
Find the missing side of the triangle. Side LaTeX: cc is the hypotenuse and sides LaTeX: aa and LaTeX: bb are legs. Leave your answer in simplest radical form. LaTeX: a=2,\:b=4
Answer:
[tex]c = 2\sqrt{5[/tex]
Step-by-step explanation:
Given
[tex]a = 2[/tex]
[tex]b = 4[/tex]
c = hypotenuse
Required
Find c
Using Pythagoras theorem, we have:
[tex]c^2 = a^2 + b^2[/tex]
Substitute values for a and b
[tex]c^2 = 2^2 + 4^2[/tex]
[tex]c^2 = 4 + 16[/tex]
[tex]c^2 = 20[/tex]
Take square roots of both sides:
[tex]c = \sqrt{20[/tex]
Express 20 as 4 * 5
[tex]c = \sqrt{4 * 5[/tex]
Split surd
[tex]c = \sqrt{4} * \sqrt{5[/tex]
Take square root of 4
[tex]c = 2 * \sqrt{5[/tex]
[tex]c = 2\sqrt{5[/tex]
The mean weight of the domesticated house cat is 9.2 pounds with a standard deviation of 3.4 pounds. If a cat has a z-score of -1.3 for its weight, how much does it weigh? Write your answer as a complete sentence.
Answer:
4.78 pounds
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 9.2 pound
σ is the population standard deviation = 3.4 pounds
z = 1.3
We are to find x
Hence,
-1.3 = x - 9.2/3.4
Cross Multiply
-1.3 × 3.4 = x - 9.2
-4.42 = x - 9.2
x = -4.42 + 9.2
x = 4.78 pounds.
Therefore the weight of the cat is 4.78 pounds

In synthetic division
Answer:
x=2, -4, -1
Step-by-step explanation:
-x³-3x²+6x+8=0
Multiply entire equation by -1:
x³+3x²-6x-8=0
Since x=2 is a solution, then x-2 must be a factor. Then:
x³+3x²-6x-8/x-2=x²+5x+4
x²+5x+4=0
Factor this:
x²+5x+4=(x+4)(x+1)=0
x=-4, -1
x=2, -4, -1

6) The perimeter of triangle ABC is 32 inches. Side B is 4 inches shorter than side A. Side C is twice as long as Side A. What is the length of side A, in inches?
Answer:
The length of side A is 9 inches.
Step-by-step explanation:
B= A-4
C= A×2
B= 9-4
C= 9×2
B= 5
C= 18
9+5+18= 32 inches
A= 9 inches
B= 5 inches
C= 18 inches
Three friends pay 1025 to rent a vacation home. Beth contributed $80 more than danny. Katie contributed $20 less than Beth. How much did Danny contribute?
Answer:
Danny contributed $295
Step-by-step explanation:
Assume that Danny contributed $x
∵ Danny contributed x
∵ Beth contributed $80 more than Danny
→ Add The amount of Danny by $80 to get the amount od Beth
∴ Beth contributed x + 80
∵ Katie contributed $20 less than Beth
→ Subtract the amount of Beth by 20 to get the amount of Katie
∴ Katie contributed x + 80 - 20
∴ Katie contributed x + 60
∵ The three friends pay $1025
→ Add their amounts and equate the sum by 1025
∴ x + x + 80 + x + 60 = 1025
→ Add the like terms in the left side
∵ (x + x + x) + (80 + 60) = 1025
∴ 3x + 140 = 1025
→ Subtract 140 from both sides
∴ 3x + 140 - 140 = 1025 - 140
∴ 3x = 885
→ Divide both sides by 3
∴ x = 295
∵ x represents the amount of Danny contributed
∴ Danny contributed $295

4. Which of the following formulas can be used to write 0.797979... as a fraction?
Answer:
The options are not shown, so i will answer this in a general way.
When we have a number like:
0.7979....
The steps to writing it as a fraction are the following ones:
1) First, you need to notice the repeating decimals.
In this case is easy to see that the repeating decimals are two, 7 - 9
2)we can multiply this number by 10^n, where n is the number of repeated decimals, in this case n = 2
10^2 = 100
then:
0.7979...*100 = 79.7979...
Now we can subtract the original number:
79.7979... - 0.7979 = 79
And this is equivalent to have:
0.7979..*100 - 0.7979... = 0.7979..*99 = 79
Then we know that if we multiply our number by 99, the outcome will be an integer.
Then we can multiply and divide by the same number (this is equivalent to multiply by one) as follows:
0.7979...*1 = 0.7979..*(99)/(99) = (0.7979..*99)/99 = 79/99
Then:
0.7979... = 79/99
Answer:
[tex]S_{inf.} - \frac{\frac{79}{100} }{1-\frac{1}{100} }[/tex]
Pretend "inf." is the infinity symbol, I couldn't put the actual symbol. It's option B.

In triangle JKL what is the value of x° if JK = KL
A) 38°
B) 60°
C) 69°
D) 71°
Answer:
A: 38º
Step-by-step explanation:
Triangle JKL is an isosceles triangle as JK=KL:
That means ∠J=∠L=71ºThe sum of a triangle's interior angles is 180º, so ∠K=180º-∠J-∠L. We know ∠J=∠L=71º, so ∠K=180º-71º-71º=38Oscar has 5 baseballs jerseys , 2 hockey jerseys , 1 basketball jersey and 3 football jerseys . What’s the ratio of hockey jerseys to the total number of jerseys
