Daniel is organizing his rock collection of 18 rocks into equal groups. How many possible ways can Daniel line up his rock collection?
2 possible ways
3 possible ways
5 possible ways
6 possible ways
Answer:
The correct options are (2, 3 and 6).
Step-by-step explanation:
It is provided that Daniel has a rock collection of 18 rocks.
He wants to organize these 8 rocks into equal groups.
The factors of 18 are:
Factor (18): {1, 2, 3, 6, 9, 18}
A group is a selection of more than 1 items. So, there cannot be 18 groups.
And there cannot be 1 group, since then Daniel would not be organizing the rocks.
So, the possible ways Daniel line up his rock collection are {2, 3, 6 and 9}.
Thus, the correct options are (2, 3 and 6).
The correct options are (2, 3 and 6).
The information is as follows:
Here we need to find the factor of 18 i.e. {1, 2, 3, 6, 9, 18}.
Since there can't be one group so the rocks are not organized.
So here the possible ways are {2, 3, 6 and 9}.
Therefore we can conclude that The correct options are (2, 3 and 6).

What is the area of a triangle whose vertices are D(3, 3), E(3, −1), and F(−2, −5)?
Answer:
10 units²
Step-by-step explanation:
Through(-2,-3); parallel to 3x+2y=5
Step-by-step explanation:
Hey there!
Firstly find slope of the given equation.
Given eqaution is: 3x + 2y = 5.......(i)
Now;
[tex]slope(m1) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex]or \: m1 = \frac{ - 3}{2} [/tex]
Therefore, slope (m1) = -3/2.
As per the condition of parallel lines,
Slope of the 1st eqaution (m1) = Slope of the 2nd eqaution (m2) = -3/2.
The point is; (-2,-3). From the above solution we know that the slope is (-3/2). So, the eqaution of a line which passes through the point (-2,-3) is;
(y-y1) = m2 (x-x1)
~ Keep all values.
[tex](y + 3) = \frac{ - 3}{2} (x + 2)[/tex]
~ Simplify it.
[tex]2(y + 3) = - 3x - 6[/tex]
[tex]2y + 6 = - 3x - 6[/tex]
[tex]3x + 2y + 12 = 0[/tex]
Therefore, the eqaution of the line which passes through the point (-2,-3) and parallel to 3x + 2y= 5 is 3x + 2y +12 =0.
Hope it helps...

simplify 61+12/4-1
please
Answer:
63
Step-by-step explanation:
The answer can be solved using the method of PEMDAS. First, you should divide 12 by 4 to get 3 for that particular part. Your equation should now be 61 + 3 - 1. The problem can now be solved from left to right. Add 3 from 61 to get 64 and subtract 1 from that number to get 63 as your final answer.

Answer:
x = 1, y = 2
Step-by-step explanation:
9x - 4y = 1 -----Equation 1
-8x - 7y = -22 -----Equation 2
-(8x+7y) = -(22) I have inserted an extra equation here so that it is easier to see how I did the next step.
Equation 2 × (-1): 8x+7y = 22 ------Equation 3
When an equation is multiplied by (-1), the -signs can be removed as two - makes one +. This applies to both sides of the equation.
Equation 1 × 22: 198x - 88y = 22 -----Equation 4
Now, Equations 3 and 4 have the same total, that means that they equal to each other.
8x+7y = 198x - 88y
Evaluate by putting the expressions with x on one side and expressions with y on the other side.
7y+88y = 198x-8x
Further evaluate.
95y = 190x
Further simplify by dividing both sides by 95.
y = 2x -----Equation 5
Now we can substitute y = 2x into equation 1.
9x - 4(2x) = 1
Evaluate.
9x - 8x = 1
Further evaluate.
x = 1 -----Equation 6
Substitute x = 1 into equation 5.
y = 2(1)
Evaluate.
y = 2

The expression 2y + 2.6 is equal to ? for y = 1.4
Answer:
5.4 :))
Step-by-step explanation:
ok so first you take 2*1.4=2.8 (you replace the Y with the number)
so now you have 2.8+2.6 which is equal to 5.4
Answer:
5.4
Step-by-step explanation:
2*1.4 is 2.8. Now the expression is y2+2.6=. Now, that we figured out what 2y is, which is 2.8, we need to add on 2.6. 2.6 + 2.8 is equal to 5.4. Now, to write out the whole equation, it would look like this.
2y+2.6=?
y2+2.6=?
2.8+2.6=?
5.4
So in the end:
2y+(2.6)= 5.4
