35x50=1,750-1,600=150. We need to find out what 150 is of 1,600.
150/1,600=?/100
1,600 divided by 100=16
do the same for 150
150 divided by 16=9.375
(you can make it whole if you want)
the answer is about 9%
You can do 15-5=10 and then you have 3 left to subtract. Which means 10-3=7
Answer:
Option D is correct. All US households are among the population of interest.
Step-by-step explanation:
The Census bureau is a national body in the U.S. and they do the survey of 250000 different households monthly. The surveys go out to all corners of the U.S. depending on which part of the nation is doing the survey next.
It shows that the entire U.S. population is of interest to the census bureau.
Adults = 9
Children = 2
Let x be the number of adults.
11-x is the number of children.
22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9 number of adults.
11 - x = 11 - 9 = 2 number of children.
To check:
22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228
(not my answer btw)
2x + 3 = 9 Move all terms not containing x to the right side of the equation.
2x = 6 Divide each term by 2 and simplify.
x=3
