PEMDAS (order of operations rules) require that we perform operations in a certain order: anything inside parentheses first, followed by any exponentiation, followed by mult. and div., finally followed by addition and subtraction.
Thus, we must evaluate 5+8÷4-1 first, as it's inside parentheses. Focusing on the division first, we get 5+8÷4-1 = 5 + 2 - 1, or 6.
Then we have 5 - [6], which comes out to -1.
Answer:
How far does Clare travel in one hour?
A: 36
How far does Clare travel in three hours?
A: 108
How far does Clare travel in 3.5 hours?
A: 126
Step-by-step explanation:
Find the Unit Value
72/2 = 36
Clare travels 36 miles per hour
Therefore, you must multiply the hours by the Unit travel time for the answers.
1 X 36 = 36
3 X 36 = 108
3.5 X 36 = 126

Sec t (theta) - 2 = 0
sec t = 2
1/ cos t = 2
cos t = 1/2
Answer:
t = π / 3 + 2 k π , or : t = 5 π / 3 + 2 kπ,
k ∈ Z
Answer:
w = -7z/2
Step-by-step explanation:
We need to solve for w in terms of z.
The equation given is:
5w + 9z = 2z + 3w
Collect like terms:
5w - 3w = 2z - 9z
2w = -7z
w = -7z/2
