<u>Answer:
</u>
The population of a city has decreased by 38% since it was last measured. If the current population is 27,900 .Previous population of city was 45000.
<u>
Solution:
</u>
Given that current population of city is 27900.
Also, population of a city has decreased by 38% since it was last measured.
Let assume that population of city when it was last measured = x
Decreased of 38% means x-38% of x . we can write this as,



So current population is 
Equating above expression to the given value of current population, we get


x=45000
Hence previous population of city was 45000.
Answer:
c true
Step-by-step explanation:
1st u read the problem and thensolve the problem
Solution:
Given:
<u>Substitute the values into the equation:</u>
- x⁶ - x/4y
- => [(-4)⁶] - (-4)/4(4)
<u>Simplify the numerator and the denominator:</u>
- => [(-4) x (-4) x (-4) x (-4) x (-4) x (-4)] + 4/16
- => [(-64) x (-64)] + 4/16
- => [4096] + 4/16
- => 4100/16
<u>Simplify the fraction:</u>
- => 4100/16
- => 1025 x 4/4 x 4
- => 1025/4
Correct option is B.
X=number of adult tickets
y=number of child tickets
I suggest this system of equations:
x+y=144
9x+6y=1164
we can solve this system of equations by substitution method.
x=144-y
9(144-y)+6y=1164
1296-9y+6y=1164
-3y=1164-1296
-3y=-132
y=-132/-3=44
x=144-y
x=144-44=100
Answer: the theatre sold 100 adult tickets and 44 child tickets.
