Mathematics

Masteriza [31]2 years ago

Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.

-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5

1. Draw an appropriate Venn diagram to depict each of the following sets. U = The set of integers. A = The set of even integers.
CaHeK987 [17]

The attached diagram represents the Venn diagram of the sets

<h3>How to draw the Venn diagram?</h3>

The sets are given as:

  • The universal set, U = The set of integers.
  • A = The set of even integers.
  • B = The set of odd integers.
  • C = The set of multiples of 3.
  • D= The set of prime numbers

From the above representation, we have the following highlights:

  • Set A and set B will not intersect, because no number can be even and odd
  • Set C and set D will intersect set A because they have common elements 6 and 2, respectively
  • Set C and set D will intersect set B because they have common elements 3 and 3, respectively

Using the above highlights, we can now draw the Venn diagram

See attachment for the Venn diagram

How many solutions are there to the equation below?
Vikentia [17]

Answer:

5x + 48 + 7x = 12(x + 4) \\ 5x + 48 + 7x = 12x + 48 \\ (5x + 7x) + 48 = 12x + 48 \\ 12x + 48 = 12x + 48 \\ 12x - 12x = 48 - 48 \\ 0 = 0
