17.7% x
-------- = -----------------
100% 110,200,000
If 110.2 million households equals 100%, then you just cross multiply to solve for what households are 17.7% - which is 19,505,400.
Ratio of children, adults and pensioners is 1 : 2 : 8/3 = 3 : 6 : 8.
Let, 3x is number of children.
So, 6x is number of adults and 8x is number of pensioners.
Now,
3x + 6x + 8x = 85
17x = 85
x = 5
Therefore, number of pensioners are 8×5 = 40.
Hence, this is the required solution.


Subtract the answer of the division problem from the sum of 33 and 7. Your answer would be:
40 - 5
Simplified:
35
Answer:
x=21
Step-by-step explanation:
Following the vertical angles, we can assume that the equation that has x and 87 are equal to each other. From then, you set them equal to each other and solve for x.
87=4x+3
84=4x subtract 3 from both sides
21=x divide by 4 to get the x alone on both sides
