Answer:
x1/2
Step-by-step explanation:
Simplify the following:
(3 x1)/6
Hint: | In (x1×3)/6, divide 6 in the denominator by 3 in the numerator.
3/6 = 3/(3×2) = 1/2:
Answer: x1/2
Answer:
<u>After a 75% increase, it would become</u>
x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x
<u>After a 50% decrease, it would become</u>
1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = 
Because
is less than x, the new amount would be less than the original.
Consider, please, this solution/explanation:
1. suppose, that number of cars is 'x', numbers of buses is 'y'.
2. according to the condition 'a total of 32', it means that x+y=32. This is the 1st equation.
3. according to the condition in one car are 3x persons, in one bus are 27y persons, and totaly 3x+27y=408 people. This is the 2d equation.
4. if to solve the system of two equations:

Answer: 13 - b., 19 - c.
Answer:
B
Step-by-step explanation:
means everything to the left of, and also everything on the line since it's equal to as well, so B is the correct answer
