There's 180 degrees in a triangle so and the two angles and then subtract by 180
Answer: A or D
Step-by-step explanation:
Answer: x=2
Step-by-step explanation:
Expand
8x−24x+16=−6−5x
simplify
−16x+16=−6−5x
add 16 to both sides
16=−6−5x+16x
simplify
16=−6+11x
regroup the terms
16=11x−6
add 6 to both sides
16+6=11x
simplify
22=11x
divide
22/11=x
simplify
2=x
switch sides
x=2

Answer:
3 * 10^6 if the answer is 3.64 * 10^6, you really ought to argue the meaning of estimate with your instructor.
Step-by-step explanation:
This is a very valuable question. Put your calculator away when you answer it. Using a calculator is sort of cheating.
1.3 * 10^3 roughly is roughly 1 * 10^3
2.8*10^3 hours is roughly 3 * 10^3
Forget the powers for now and just work with the 1 and 3
1*3 equals 3.
10^3 * 10^3 = 10^6 when the base of two numbers is the same (10 in this case) then the powers are added.
10^(3 + 3) = 10^6
So the answer is roughly 3*10^6
Now you can take out your calculator and get the answer.
1.3*10^3 * 2.8 * 10^3 = 3.64 * 10 ^ 6
Notice that the estimate (done in my head) is close enough to tell you what the answer should be. On a test, that's a very handy skill.
