Answer:
103.
Step-by-step explanation:
If you plug in 9 for the value of x in the equation, 103 is your answer.
Square roots the square root of 1 is one square root of 2 is 4 square root of 3 is 9 and ect.
Imagine for a group of 15 (8 boys and 7 girls), you will have 8 girls. So the ratio of girls to total campers is 8/15
Because we have 195 campers, we have 8/15 = x/195
solve for x
x= 104 girls
and we have 195 - 104 = 90 boys
If in 2 years, your car is worth $15000, then x2 so then you’ll make it 4 years. $15000+$15000= $30000 but then you’ll have to know what the last year is so since in 2 year your car turned $15000 more then you divide it by 2 which is $7500. Then, you add $15000+$15000+$7500 which is $37,500.
So this is actually composed o 2 sentances
20x-18<50 AND 50<36x-16
so solve each and find solutions where x is the same in both sentances
20x-18<50
add 18 to both sides
20x<68
divide both sides by 20
x<3 and 2/5
then the second sentance
50<36x-16
add 16 to both sides
66<36x
divide both sides by 36
1 and 5/6<x
so
since it is and, combine
3 and 2/5>x>1 and 5/6 or
17/5>x>11/6
the solution is
S={x|17/5>x>11/6}
