The first thing we are going to do to solve the problem is to define what associative property is:
Associative property Property that is fulfilled if, given any three elements of a given set, it is verified that there is an operation that verifies equality
An expression that meets the definition is:
(x + 3) + 7 = x + (3 + 7)
We observe that both members of equality are identical, but written in different ways.
Answer:
B) (x + 3) + 7 = x + (3 + 7)
Answer in explanation
Step-by-step explanation:
for each row, the y- coordinate of the point where the line crosses the x- axis is zero. The point where the line crosses the x- axis has the form (a,0) ; and is called the x-intercept of the line. The x- intercept occurs when y is zero. Now, let's look at the points where these lines cross the y-axis
Answer:
Step-by-step explanation:
Koris current age = x
Josephs current age = 7 + x
Koris age after four years = x + 4
Josephs age after four years = 7 + 4 + x = 11 + x
In 4 years the sum of their ages will be 75.
So, (x + 4) + (11 + x) = 75
= 2x + 15 = 75
2x = 75 - 15
x = 60/2 = 30
Therefore koris current age = 30
Josephs current age = 30 + 7 = 37
Hope this helps . Have a nice day!
