Answer:
Sorry if I am wrong, but I believe it is (-33/2,38)
-33/2 being x
38 being y

Answer:
$16.60
Step-by-step explanation:
2.5x + 1.25(x - .20) = 31.25
2.5x + 1.25x - .25 = 31.25
3.75x - .25 = 31.25
3.75x = 31.25 + .25
3.75x/3.75 = 31.50/3.75
x = 8.40
y = x - .20
y = 8.20
1x + 1y = 16.60
Steps:
(x-2)=4x
Pretend that there is a one in front of x-2
1(x-2)=4x
Multiply the bracket by 1
x-2=4x
Move x to the other side .Whenever you move a number or letter the sign changes.
x-x-2=4x-x
-2=3x
Divide by 3 for -2 and 3
-2/3=3/3 x
x=-2/3
Check answer by using substitution method
(-2/3-2)=4(-2/3)
(-2/3-6/3)=-8/3
-8/3=-8/3
Answer is -2/3

The Venn diagram shows three types of numbers: odd (O), even (E), and prime (P). Which is represented by Ø?
(A) O ⋃ P (B)E ∩ P (C)O ⋃ E (D)E ∩ O
Answer:
(D) E ∩ O
Step-by-step explanation:
The Venn diagram is reproduced and attached below.
In the Venn diagram, the sets of Odd(O) and Even(E) numbers are disjoint, i.e. there is no intersection.
We can also say the intersection of sets O and E is the empty set.
Therefore: E ∩ O is represented by the empty set Ø.
Generally speaking, a number cannot be even and odd at the same time.
The correct option is D
