Answer:
Jane bought 15 stickers per day.
Step-by-step explanation:
Given;
Total number of stickers Jane has = 237
Number of stickers 2 weeks ago = 27
To find : Number of stickers she bought each day for two weeks.
Solution,
Let the number of stickers she bought everyday be x.
∴ Number of stickers for 2 weeks =
Now according to question,
Total number of stickers = Number of stickers 2 weeks ago + Number of stickers she bought for 2 weeks
Thus the number of stickers she bought everyday for 2 weeks is 15.
So average=(total of scores)/(number of tests)
needs at least average of 70
at least is represented as greater than or equal to or the sign (<u>></u>)
70<u>></u>(total)/(number oftests)
since we have 3 tests, we have to have 3 scores so
70<u>></u>(x+y+z)/3
he scored 85 and 60
70<u>></u>(x+85+60)/3 (doesn't matter which to subsitute)
70<u>></u>(x+145)/3
multiply obht sides by 3
210<u>></u>x+145
subtract 145 from both sides
65<u>></u>x
he needs to get at leas 65 on his third test
I believe that x=32. If you know that all angles together equals 180 then you can add all of these equations in n-solve in the calculator and the put =180,x then it will give you the answer.
Answer:
A. -500
Step-by-step explanation:
Find the slope using rise over run (change in y / change in x)
Find the change in the y values (height of the plane):
24,000 - 18,000
= 6,000
Find the change in the x values (miles from the airport)
(60 - 72)
= -12
Divide 6000 by -12:
6000/-12
= -500
So, the slope of the plane's path is A. -500
