Eight more than three times a number is 32

Mathematics

Morgarella [4.7K]2 years ago
8 0

Answer:

The number is 8

Step-by-step explanation:

3x + 8 = 32

3x = 24

x = 8

________

A number can be denoted as x. 3 times a number is 3 of that number, and 8 more than a number is that number plus 8. This relationship can be given by:

x + x + x + 8 = 32

(x + x + x) + 8 = 32

3x + 8 = 32

3x + 8 - 8 = 32 - 8

3x = 24

3x/3 = 24/3

x = 8

Hey can you please help! posted picture of question
frosja888 [35]
The solution of the system can be x - 3y = 4 only if both the equations can be simplified to x - 3y = 4.

This will mean that both the equations will result in the same line which is x - 3y = 4 and thus have infinitely many solutions.

Second equation is:

Qx - 6y = 8 
Taking 2 common we get:

(Q/2)x - 3y = 4

Comparing this equation to x- 3y = 4, we can say that 

Q/2 = 1
So,
Q = 2

Therefore, the second equation will be:

2x - 6y = 8

Picking a heart then a club would be 1/4 x 1/4 = 1/16

Answer: 1/16
