Answer:
x = 18
Step-by-step explanation:
This problem can be solved using concept of Pythagoras theorem.
Pythagoras theorem states that in a right angled triangle, if "a" and "b" are sides containing the right angle and h is hypotenuse then the relation between them is 
_________________________________________
Given in the problem
a = 24
b = x
h = x+12
applying Pythagoras theorem

for (x+12)^2 we have used formula 
Thus, value of x is 18.
Answer:
Step-by-step explanation:
You cross multiply. So it's 14 times 250 divided by 115.
That's how much you would add to the 250 mixture.
14 times 250 is 3500, Divided by 150= 23 and a third.
It does say round to the nearest gram.
So we had to add about 23 g to 250 g of flour.
