Answer:
.
Step-by-step explanation:
Answer: It’s the third answer.
Step-by-step explanation:
There are 2.54 cm in one inch and 12 inches in one foot, so 2.54x12 = 1 foot. Multiply this by 2 to get 2 feet.
90-69=21 degrees. This is our target answer. We'll write an equation to do this:
2x-1=21
Add 1 to each side to get:
2x=22
Divide by 2 to get that x=11
Plugging this in, we see that 2(11)-1+69=90, so our answer is correct.

Step-by-step explanation:
If the tens digit of the number is X and the ones digit is Y then the number is equal to 10*X + Y
If you reverse the digits then the number is equal to 10*Y + X
If reversing the digits decreases the number by 36 then
10*Y + X = 10*X + Y - 36
The sum of the digits is 4 so X + Y = 4 ==> X = 4 - Y
Substitute this value of X into the 1st equation
10*Y + (4 - Y) = 10*(4 - Y) + Y - 36
9*Y + 4 = 40 - 9*Y - 36
18*Y = 0
Y = 0
I hope it helps you
So X = 4 - 0 = 4 and the number is 40
so, let's check 40 - 04 = 36
Answer:
The population of the town at the end of 2017 was 65,550.
Step-by-step explanation:
The population of the town was 60,000 in the beginning of 2016.
In 2016, the total population is increased by 15%.

Therefore the population is increased by 9000 and the population of the town at the end of 2016 was

In 2017, the total population is decreased by 5%.

Therefore the population is decreased by 3450 and the population of the town at the end of 2017 was

Therefore the population of the town at the end of 2017 was 65,550.
