2x-y=2. Y=2x+1
Answer:
No Solutions
Step-by-step explanation:
1. Substitute the 2x + 1 in for the y in the first equation. Rewrite it as 2x - (2x + 1) = 2.
2. Add the opposite and change the equation to 2x + -1(2x + 1) = 2.
3. Use the distributive to make the equation look like this: 2x + -2x + -1 = 2
4. Combine like terms and add 2x and -2x. They cancel each other out.
5. You will end up with -1 ≠ 2. Since -1 and 2 are not equal, there are no solutions.

Mr. Sanchez’s class sold fruit pies for $1.65 each, and Mr. Kelly’s class sold bottles of fruit juice for $1.36 each. Together, the classes sold 79 items and earned $118.17 for their school. Write and solve a system of equations to determine how many pies and how many bottles of juice were sold.
46 pies and 33 bottles of juice
37 pies and 42 bottles of juice
33 pies and 46 bottles of juice
42 pies and 37 bottles of juice
I need an answer on how many pies and bottles of juice it is.
Answer:
37 pies and 42 bottles of juice
Step-by-step explanation:
Let x be pies and y be juice
x+y=79 represents # of items sold
1.65x+1.36y=118.17 represents how many of each to make $118.17 based on cost
y=-x+79
1.65x+1.36(-x+79)=118.17
x=37
79-37=42

What extraneous solution does Miku obtain?
z=z=
Extraneous solutions are untrue solution of an equation
Mike does not obtain any extraneous solutions
How to determine the extraneous solutions
The equation is given as:
[tex]\sqrt{z^2+2z-3}=z-3[/tex]
When squared, it becomes
[tex]z^2+2z-3=z^2-6z + 9[/tex]
Evaluate the like terms
[tex]2z-3=-6z + 9[/tex]
Collect like terns
[tex]6z + 2z = 9 + 3[/tex]
Evaluate the like terms
[tex]8z = 12[/tex]
Divide through by 8
[tex]z = 1.5[/tex]
Substitute 1.5 for z in the given equation
[tex]\sqrt{z^2+2z-3}=z-3[/tex]
[tex]\sqrt{1.5^2+2*1.5-3}=1.5-3[/tex]
Evaluate
[tex]\sqrt{2.25}=-1.5[/tex]
Determine the square root of 2.25
[tex]-1.5=-1.5[/tex]
Hence, Mike does not obtain any extraneous solutions

At a cost of $8 per pound how many ounces of almonds can be bought for $2.05
Answer:
4.1 Ounces can be bought
Step-by-step explanation:
1 Pound = 16 Ounces
16Oz. = $8
Divide both by the common factor of Eight (8)
16/8 = 2 Oz.
8/8 = $1
2 Oz = $1
1 Oz. = .50
2.05/.50 = 4.1
If each ounce cost .50 cents 4.1x.50 should equals $2.05
and .50x16 should be 8

Which number line shows the solutions to x + 6 < 13?
Answer:
The correct answer is C.
Step-by-step explanation:
When you solve for the inequality, you subtract 6 from 13 to get x < 7. because the inequality doesn't include the value of 7, the circle point on the number line is open.

Hey!
Let's see... if they walk 10 feet in 6 seconds, then they walk about half a foot a second (0.6 to be exact.)
Multiply 0.6 by 45 and your answer should be.. 27. So, they walk 27 feet in 45 seconds.
Next, we keep multiplying 0.6 by a number over 45, but under 100, and the total amount of time it takes for a penguin to was 45 feet is... 75!
We know this because 75x0.6 is 45. and 75 is the number of seconds it takes to walk 45 feet for the penguin.
Your answer for #1 is 27
Your answer for #2 is 75

find the dimensions of a rectangle that has a length 3 inches longer than it’s width and has an area of 40in^2
Answer
length: 8 inch and width: 5 inch
Explanation
Let width be x,
then the length: x + 3
solve:
[tex]\sf (x+3)(x) = 40[/tex]
[tex]\sf x^2+3x = 40[/tex]
[tex]\sf x^2+3x-40=0[/tex]
[tex]\sf x^2+8x-5x-40=0[/tex]
[tex]\sf x(x+8)-5(x+8)=0[/tex]
[tex]\sf (x-5)(x+8)=0[/tex]
[tex]\sf x = 5 \ or \ -8[/tex]
As width cannot be negative, width will be 5.Find for length:

Find the probability of having 2, 3, or 4
successes in five trials of a binomial
experiment in which the probability of
success is 40%.
p = [?] %
Round to the nearest tenth of a percent.
Answer:
16% for 2 successes, 6.4% for 3 successes, 2.6% for 4 successes, and 1% for 5 successes
Step-by-step explanation:
Since the success rate of a binomial experiment is 40%, converted to 0.4, you get the equation of f(x) = (0.4)^x, for where x is the amount of successful experiments
For the success of 2 experiments:
f(2) = (0.4)^2
=0.16 => 16%
For the success of 3 experiments:
f(3) = (0.4)^3
= 0.064 => 6.4%
For the success of 4 experiments:
f(4) = (0.4)^4
= 0.0256 => 2.56% => ~2.6
For the success of 5 experiments:
f(5) = (0.4)^5
= 0.01024 => 1.024% => ~1%

Change the following mixed number to an improper fraction. Reduce if possible.
7 81/1000
The answer is 7081/1000
Step-by-step explanation:
7 = 7×1 = 7×1000/1000 = 7000/1000
7000/1000 + 81/1000 = 7081/1000
this can't be further simplified, as the only factors of 1000 are
2 and 5 and then multiples of them.
neither of them can be a factor of 7081 (which is clearly neither an even number nor a multiple of 5).

determine all combinations of lengths that could be used to make a traingle 1,3,6,8
Answer:
3, 6, and 8 for a triangle
Step-by-step explanation:
So, let's start with what we know
The sum of the 2 lesser lengths of a triangle must be greater than the greatest length of a triangle. Otherwise, it cannot be a triangle
a + b > c
Note: variables a and b are the lesser lengths of a triangle, and c is the greatest length.
We are to list out the possible combinations of triangles here with lengths 1, 3, 6, and 8.
So, with the formula above, we will get the combination of
3,6,8
Any other combinations of triangle lengths will not work

Ivan has a piece of material that is 4 feet long. He cuts it into 7 equal pieces. Which equation shows how to find the length, in feet, of each piece of material?
You have not provided the options, but this solution is an equation that will work:
Answer:
4 / 7 = x
Step-by-step explanation:
Since the total material is 4 feet long, we can divide 4 feet by 7, the number of equal pieces cut, to see how long each piece is.
This gives us an answer of 4/7 or about 0.571
