Answer:
Solution for 2x-10=16 equation:
2x - 10 = 16
2x = 16 + 10
2x = 26 (divide both sides by 2 to get x)
2x/2 = 26/2
x = 13
Step-by-step explanation:
Solve for one variable x or y first. So lets solve for x. If you take the first equation x= -12 -5y. You then plug that into the second equation
5(-12-5y) +4y = 24
now you solve for y
-60 - 25y + 4y =24
-21y=84
y=-4
Now you plug in y back into either equation and you get x=8
Answer:
Step-by-step explanation:
If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.
<u>We have n = 50 and:</u>
- 2^5 = 32 < 50
- 2^6 = 64 > 50
As per above described 2 to k rule, we are taking k = 6.
So 6 classes should be used.

Let's solve for x:
100x=1000
Divide by 100
x=10
