12x+6y=120
4x+y=30
Answer:
x=5, y=10. (5, 10).
Step-by-step explanation:
12x+6y=120
4x+y=30
-------------
2x+y=20
4x+y=30
----------------
y=20-2x
4x+(20-2x)=30
4x+20-2x-30
2x-30-20
2x=10
x=10/2
x=5
4(5)+y=30
20+y=30
y=30-20
y=10
Answer:
12x+6y=120
4x+y=30
using elimination method.
12x+6y=120 -----(1) ×4
4x+y=30----------(2) ×12
48x+24y =480
-48x+12y =360
12y =120
y= 10
To get x sub. y for 10 into equation (2)
4x+y=30
4x+10=30
4x=30-10
4x=20
x=5
x=5 , y=10
Seven times a number, x

How to complete this problem?
Write out from word format to number format.
We have the word expression:
Seven times a number x.
Seven and x are the two terms included in our expression, and we'll be multiplying both of the terms.
Times is short for multiplying.
When including key words:
'Seven' 'times' 'x'.

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

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

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

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

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.

A set of speakers for a classroom cost 365.23. The school needs to place them in 42 classrooms. How much will it cost to place speakers in all of the classrooms?
Answer:
$15339.66
Step-by-step explanation:
Let's start with what we know,
1 classroom = 1 set of speakers
1 set of speakers = $365.23
The school has 42 classrooms
Find how much it will cost to place the speakers in all of the classrooms
To find the amount it will cost, you will need to substitute values
1 school = 42 classrooms
= 42 sets of speakers
= 42 (365.23)
= 15339.66
It will take $15339.66 to place the speakers in all of the classrooms at the school.

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
