Answer:
All you have to do is combine the like terms. Once you do that you get: -4x+3y=-11
Answer:
This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.
Explnation:
z = (x - mu)/sd
z = (2625 - 2600)/50 = 25/50 = 0.5.
Consulting the z-table, P(z <= 0.5) = 0.6915.
P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.

-x-29=13+2x
-29=13+3x
-42=3x
x=-14
There are a total of 48 students. Being 42 boys as mentioned earlier and 6 girls total attending too.

X+7<23
x<23-7
x<16
So, all numbers from zero to 15
Those are 16 positive integers
