Use slope formula.
Answer: The missing number is 55
The denominators are 20 and 100. We multiply by 5 to jump from the smaller denominator to the larger.
Do the same for the numerators
11*5 = 55
Or you can solve the proportion below for x
11/20 = x/100
11*100 = 20*x
1100 = 20x
20x = 1100
x = 1100/20
x = 55
Answer:
12
Step-by-step explanation:
This is a proportion question.
8/x = 12/(12 + 6)
8/x = 12/18 Reduce the right hand side
8/x = 2/3 Cross multiply
2x = 8*3 Combine the right side
2x = 24 Divide by 2
x = 24/2
x = 12
The answer is HJ i took the test and got it right :)
