Answer:
Well if you add up all 3 angles in a triangle you’d get 180 degrees as the answer.
So we can. Jus substitute.
For number 19 you can do this
57+x+x+87+50=180
Now combine like terms
194+2x=180
Now solve
x=-7
Now we can subsitute that into angle A
57+ (-7) which is 50
Measure of angle A is 50.
For number 19 it’s the same thing.
9x+14+16x-4+80=180
Now combine like terms
25x+90=180
Solve
25x= 90
x= 3.6
Now subsitue for A
3.6*9+4 which is 36.4
A is 36.4

Please find the slope of these tables
Step-by-step explanation:
To calculate each slope, just take any two points from each table, and plug them into this formula:⤵⤵⤵
(It'll be a bit small btw)
[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]
Table 1: I chose points (13,1) and (5,21)
21 - 1 = 20
5 - 13 = -8
Simplified = -5/2 ⬅ Slope
Table 2: I chose points (4,16) and (9,19)
19 - 16 = 3
9 - 4 = 5
3/5 ⬅ Slope
Table 3: I chose points (0,6) and (9,0)
0 - 6 = -6
9 - 0 = 9
Simplified = -2/3 ⬅ Slope
Table 4: I chose points (-8,1) and (-8,17)
17 - 1 = 16
-8 - (-8) = -8 + 8 = 0
Undefined slope (meaning the line will just be verticle)
Table 5: I chose points (2,3) and (3,5)
5 - 3 = 2
3 - 2 = 1
Simplified = 2 ⬅ Slope
Hope this helps :)
Forty percent of the beads in a bag of more than 10,000 beads are yellow. Suzy pulls out 10 beads, one at a time with replacement, and notes that eight of these beads are yellow. She says the next bead pulled out will not be yellow because a yellow bead has been pulled out too many times in a row.Is Suzy’s reasoning correct?
Answer:
No, it is true that the probability of pulling a yellow bead is 0.40, but Suzy should not expect that exactly 40% of such a small number of beads pulled will be yellow. A large city's transit department claims that only 10% of city buses run off schedule.

X + 124
Answer:
x = 126°
Step-by-step explanation:
150 = x + 124
Subtract 124 from 124 and cancel it out. Whatever you do to one side you have to do to the other so subtract 124 from 150.
150 - 124 = x
Solve.
26 = x

Ellie hikes 1/2 of a mile every 10 minutes. How far does she hike in 1 hour?
Answer choices:
3
5
4
6
Answer:
3miles
Step-by-step explanation:
10 minutes is 1/6 of an hour, so in 1 hour ellie would hike 1/2*6=3miles
Answer:
Step-by-step explanation:
There are various ways in which we can solve this problem.
If we're told that Ellie can hike 1/2 mile in 10 minutes, then multiplying both sides of "1/2 mile = 10 minutes" by 6 yields 3 miles in 60 minutes.
Alternatively: "1/2 mile = 10 minutes" becomes "1 mile in 20 minutes" by the same approach. Then, multiplying both sides by 3 yields "3 miles in 60 minutes," or "3 miles in 1 hour."

You can buy 3 apples at Quick Mart for $1.17. You can buy five of the same apples at Shop & Save for $2.40
How much will you save per apple if you buy them at the cheaper store?
Answer:
$0.09 or 9 cents
Step-by-step explanation:
1.17/3=0.39
2.4/5=0.48
0.48-0.39=0.09
Answer:
Well you can divide them by each
1.17/3 which is 0.39 (quick mart)
2.4/5 Which is 0.48 (stop and save)
39 cent is what you pay at the cheaper store
9 cents is what you would save
