Answer:
1) Correct
2) Wrong
3) Operate Within Parentheses
4) 60°
Step-by-step explanation:
The original equation is correct because 180 - (60 + 60) = 180 - 120.
180 - 120 = 60
If Puzzled Penguin operated within the parentheses first he would have arrived at the correct answer.
Hope this helped.
Answer:
9.
Step-by-step explanation:
So basically, we need to find out x. So we know that ZX = YW because ZY and XY are already congruent and it's just adding a three to the value because of YX. We can find out x.
ZX = YW
5x + 17 = 10 - 2x
x = -1
Then we can find out the value of ZX and YW by plugging in x.
5(-1) + 17 = ZX = YW = 12.
Then we see that YX is 3 so...
ZX = ZY + YX
12 = ZY + 3
ZY = 9
So the answer is 9.
There are 60 students. The winner got 70% of the 60 students votes. Let's work this one out to get the answer.
First, you need to figure out what 70% of 60 is, by using this equation.
60 x .70 = 42.
Now that you know the answer is 42, you now know that 70 percent of 60 is 42.
So, the class president got 42 winning votes!

Since opposite angles are equal, 8x+12=5x+57. Subtracting 5x as well as 12 from both sides, we get 3x=45. . Dividing both sides by 3, we get x=15. Plugging x=15 into 5x+57, we get 5*15+57=75+57=132
I think is on the mile 3 just look at the example:
I am not sure if I am correct, but I hope I am :)
