what's the gcf of 3x and 12x
Answer: GCF- is 3x
Step-by-step explanation:
So first you will ignore the X.
You will then find the GCF of 3 and 12.
The calculated value of the gcf of 3x and 12x is 3x
Calculating the gcf of 3x and 12xFrom the question, we have the following parameters that can be used in our computation:
Expressions = 3x and 12x
Expand both expressions
So, we have
3x = 3 * x
12x = 2 * 2 * 3 * x
Multiply the common factors
GCF = 3 * x
Evaluate
GCF = 3x
Hence, the gcf of 3x and 12x is 3x

A paint that contains 26 % green dye is mixed with a paint that contains 14 % green dye. How many gallons of each must be used to make 100 gal of paint that is 22 % green dye?
Answer:
66and2/3 gallons of 26% and 33and1/3 of 14%
Step-by-step explanation:
x is the gallons of 26% green dye and y is the gallons of tve 14% one. we know that the totall gallons of dye in the ens are 100=>x+y=100=>x=100-y. 26%*x+14%*y=22%*100

Answer: look in the explanantion :)
Step-by-step explanation:
So basically when something is y=2, that means that its just a horizontal line at the number 2
so it would just be a straight horizontal line that is located at the y point of 2

Joe buys a compact disc that costs $29.99. He give the store clerk $50.00.
How much change should he get?
Answer:
$20.01
Step-by-step explanation:
Simply subtract $29.99 from $50.00 so, your problem should be set up like this:
You substitute the numbers with 10s, but there cannot be more than one.
Answer:
$20.01
Step-by-step explanation:
You should subtract 50.00 and 29.99, and since there are three zeros, you have to borrow from the five, making it a four. Then, you make the first zero into a 10, then borrow from that one, making it a nine, same with the second zero. Then, for the third zero, you only borrow one from the second zero, turning the second one into a nine and the third on into a 10. You then start the subtracting process. This is the first part to the problem:
50.00 - 29.99 = ?
Then, this is what you should have after:
49.91(0) - 29.99 = ?
This is what you get after:
20.01
Then, add the dollar sign. You will get:
$20.01

A school board voted whether to adopt new math books. Those that voted yes
out numbered those that voted no by a ratio of 5 to 1. If 18 school board
members voted, how many voted yes for new math books and how many
voted no?
Answer:
15 people voted yes and 3 people voted no.
Step-by-step explanation:
Given that:
Ratio of yes to no = 5 : 1
Total number of board members who voted = 18
Let,
x be the number of times.
5x+x = 18
6x = 18
Dividing both sides by 6
[tex]\frac{6x}{6}=\frac{18}{6}\\x=3[/tex]
People who voted yes = 5(3) = 15
People who voted no = 3
Hence,
15 people voted yes and 3 people voted no.

Answer:
D. 2/5
Step-by-step explanation:
The slope is the x-coefficient when the equation is solved for y.
2x -5y = 9 . . . . . . . given
-5y = -2x +9 . . . . . .subtract 2x
y = (-2/-5)x +9/(-5) . . . . divide by -5
y = 2/5x -9/5
The coefficient of x is 2/5. That is the slope of the line.
The slope is 2/5.

Answer: 225 adult tickets, 375 student tickets
Step-by-step explanation:
a = adult tickets
s = student tickets
a + s = 600 (the adult and student ticket added together should equal 600)
6.00a + 4.50s = 3,037.50 ($6 multiply by the adult ticket plus $4.50 multiply by the student ticket should equal to 3,037.50)
a = -s + 600 (get one of the variable by itself by subtracting it from one side)
6 (-s + 600) + 4.5s = 3,037.5 (substitute the a for -s + 600)
-6s + 3600 + 4.5s = 3,037.5 (combine like terms)
-1.5s + 3600 = 3,037.5 (subtract 3600 from each side)
-1.5s = - 562.5 (divide -1.5 from each side)
s = 375
600 = 375 + a (substitute s for 375)
a = 225
show that each quadrilateral with the given vertices is a parallelogram.
J(-2,-2), K(-3,3), L(1,5), M(2,0)
9514 1404 393
Answer:
J +L = K +M = (-1, 3)
Step-by-step explanation:
The figure JKLM is a parallelogram if the midpoints of the diagonals are the same point. That is, ...
(J +L)/2 = (K +M)/2
Multiplying by 2 makes this a simpler test:
J +L = K +M
In this quadrilateral, those sums are ...
J +L = (-2, -2) +(1, 5) = (-2+1, -2+5) = (-1, 3)
K +M = (-3, 3) +(2, 0) = (-3+2, 3+0) = (-1, 3)
The midpoints are the same, so the quadrilateral is a parallelogram.

-2 (m+3) - 5m = -34
Help please
Answer:
m = 4
Step-by-step explanation:
Given
- 2(m + 3) - 5m = - 34 ← distribute and simplify left side
- 2m - 6 - 5m = - 34
- 7m - 6 = - 34 ( add 6 to both sides )
- 7m = - 28 ( divide both sides by - 7 )
m = 4

Expand and simplify
Answer: 3x^2 − 11x − 42
Step-by-step explanation:
Simplify (x − 6) (3x + 7)
Expand (x − 6) (3x + 7) using the FOIL Method.
Apply the distributive property.
x (3x + 7) − 6 (3x + 7)
Apply the distributive property.
x (3x) + x ⋅ 7 − 6 (3x + 7)
Apply the distributive property.
x (3x) + x ⋅ 7 − 6 (3x) − 6 ⋅ 7
Simplify and combine like terms.
Rewrite using the commutative property of multiplication.
3x ⋅ x + x ⋅ 7 − 6 (3x) − 6 ⋅ 7
Multiply x by x by adding the exponents.
Move x.
3 (x ⋅ x) + x ⋅ 7 − 6 (3x) − 6 ⋅ 7
Multiply x by x.
3x^2 + x ⋅ 7 − 6 (3x) − 6 ⋅ 7
Move 7 to the left of x.
3x^2 + 7 ⋅ x − 6 (3x) − 6 ⋅ 7
Multiply 3 by −6.
3x^2 + 7x − 18x − 6 ⋅ 7
Multiply −6 by 7.
3x^2 + 7x − 18x − 42
Subtract 18x from 7x.
3x^2 − 11x − 42

Answer:
length = 3√5
distance = √13
Step-by-step explanation:
length = √[(lenght(1,-2)to(4,-2))² + (length(4,-2)to(4,4))²]
length = √ 3²+6²
=√9+36
=√45=3√5
distance
d = √(x1-x2)²+(y1-y2)²
d= √(5-3)² + (-2-1)²
d=√2²+(-3)²
d=√4+9
d=√13
