Answer:
z = 6
Step-by-step explanation:
sin (9z - 1) = cos (6z + 1)
90 - (9z - 1) = 6z + 1
90 - 9z + 1 = 6z + 1
9z + 6z = 90
15z = 90
z = 6

-8y=24
We want to isolate y to get the value of 1y. Divide both sides by -8
y= -3
Final answer: y=-3

This is the associative property of addition (D).
It states that when adding three terms, the sum is equal no matter the grouping (parentheses).
Answer:
14/3
Step-by-step explanation:
When 56 shares are evenly distributed between 12 people, each person gets equal number of shares.
The number of shares gotten by each person is the ratio of the total number of shares to the total number of people. It is given by the formula:
number of shares gotten by each person = total number of shares / total number of people
number of shares gotten by each person = 56 shares / 12 people
number of shares gotten by each person = 14/3 shares
There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Total number of students in the school = 209
Ration of the boys to girls in the school = 6:5
Let us assume the common ratio to be = x
Then
6x + 5x = 209
11x = 209
x = 209/11
= 19
Then
The number of girls in the school = 19 * 5
= 95
So there are a total of 95 girls in the school that has a total of 209 students.
