Answer: Choice A) Set W is all the unique three-digit numbers using the digits 1, 3, and 5
==========================================================
Explanation:
The original set uses the digits {1,2,3,4,5}. We can only use those digits. Nothing else. So that means we can't use 0, 2, 4, 6, or 7. This rules out choices B through D.
Only choice A is left. This answer choice involves 1,3 and 5 which is the correct subset of digits to use.
--------
Put another way, if set B was a subset of set A, then everything in B must also be found in A. Having B = {2,4,6} and A = {1,2,3,4,5} shows B is not a subset of A. We see a counter example has 6 in B, but not in set A.
This allows us to rule out choice B. Similar ideas apply to the answer choices C and D as well.

A

3|3t+1|=2|6t+3| Need hep
Answer:
your answer would be t=-1 or t=1
Step-by-step explanation:
-(2t-3) = 3t-2
Multiply
-2t+3 = 3t-2
Rearrange and Add up
-5t = -5
Divide both sides by 5
-t = -1
Multiply both sides by (-1)
t = 1
Which is the solution for the Negative Case
Solve the Positive Case
(2t-3) = 3t-2
Rearrange and Add up
-t = 1
Multiply both sides by (-1)
t = -1

What are statistics?Statistics is a mathematical tool defined as the study of collecting data, analysis, understanding, representation, and organization. Statistics is described as the procedure of collecting data, classifying it, displaying that in a way that makes it easy to understand, and analyzing it even further.
We have:

The first step is to write 13% in decimal form. We then multiply, .13 x 667.63=$86.79
The sum of two numbers is 50. The first number is 18 less than the 2nd number. What are the
2 numbers?
Answer:
2y + 2 + y = 50 (combine like terms)
3y + 2 = 50
3y = 50 - 2
3y = 48
y = 16
Substitute 16 for y in either equation 1 or 2 and solve for x (I chose equation 1):
x + 16 = 50
x = 50 - 16
x = 34

what is 3/4 - (-4/5)
Answer: 1,55
Step-by-step explanation:
3/4 - (- 4/5) = 3/4 + 4/5 = (3x5)/20 + (4x4)/20 = 15/20 + 16/20 = 31/20 = 1,55
3/4 - (- 4/5) = 3/4 + 4/5 = 0,75 + 0.8 = 1,55

What is the coordinate of the midpoint of DA?
D
Answer:
6
Step-by-step explanation:
Coordinate of point D = -6
Coordinate of point A = 18
The coordinate of the midpoint of DA = the coordinate of the point that is half the distance from D to A.
Distance of DA = |18 -(-6)| = |18 + 6| = 24
Midpoint = ½ the distance of DA = ½*24 = 12
Coordinate of the midpoint of DA = coordinate of D + 12 = -6 + 12 = 6
Or,
Coordinate of A - 12 = 18 - 12 = 6
Therefore, coordinate of the midpoint of DA = 6.

Solve for Y!
Answer:

Step-by-step explanation:
120 + 6y = 180
6y = 60
y = 10
Answer:
y = 10
Step-by-step explanation:
6y + 120 = 180
6y = 60
y = 10
Solve for x (see image)
Answer:
x = 18
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + 24^2 = ( 12+x)^2
FOIL the right side
x^2 +576 = 144 + 24x + x^2
Subtract x^2 from each side
576 = 144 + 24x
Subtract 144 from each side
576-144 = 24x
432 = 24x
Divide each side by 24
432/24 = 24x/24
18=x

if jessie had 3 feet of string and maxine had 34 inches of string, who had more string
Answer:
Jessie
Step-by-step explanation:
12 inches = 1 foot
Jessie has 3 feet of string. So, multiply 12 by 3.
12 × 3 = 36 inches
36 inches is greater than 34 inches. So, Jessie has more string.
