Answer:
1: 20
Step-by-step explanation:
9/180 set the problem as a fraction then simplify it.
You are given the information that he takes six lessons per week. First we will calculate the total lessons he could potentially take per year.
6 • 52 = 312
He could potentially take 312 lessons in one year.
Now that you know this information, you simply subtract the days he missed from that total.
312 - 5 = 307
Your final answer: Peter took 307 lessons during the year.
Answer:
1) I believe 6 (im wrong I know it)
Step-by-step explanation:
you do whatever like 13902-1 , im so smart
Since they're vertical angles, they're equal in degree measure
since they're equal, we can make the two expressions equal to each other
5a - 1 = 2a + 20
add 1 to both sides
5a = 2a + 21
subtract 2a from both sides
3a = 21
divide both sides by 3a
a = 7
now, plug the answer you found for a into one of the two expressions
5a - 1 becomes (5*7) - 1, which equals 34
to double check that they're equivalent (since they're vertical angles)
2a + 20 becomes (2*7) + 20, which equals 34
both angles are 34 degrees!
Answer:
x = 2
y=6
Step-by-step explanation:
6 + 2 = 8
2 + 6 x 2 = 14
Hope this helps
Have a blessed day!
