Answer:
-3
Step-by-step explanation:
5280 ÷ 2 = ?
How many times does 2 go into 5280?
5280 ÷ 2 = 2640
2 goes into 5280, 2640 times!
Answer:
<em>x=1, y=1, z=0</em>
Step-by-step explanation:
<u>System of Equations</u>
We are required to solve the system of equations by elimination:
Adding [1] and [3], and subtracting [1] and [2]:
Multiplying [5] by -3 and adding to [4]:
Solving:
Substituting into [5]:
Simplifying:
z=0
Substituting into [3]
Operating:
x=1
The solution is
x=1, y=1, z=0
The answer is obviously {2}since there are NO EVEN PRIME NUMBERS, except for 2. So,there is only 1 element.
w/4 = 43
Multiply by 4 for both sides
w/4(4)= 43(4)
Cross out 4 and 4 , divide by 4
w= 172
Answer: 172
