Answer: 
Step-by-step explanation:
Given : A man earned x pesos in 10 days and spent y pesos during each of those days.
i.e. Total earning in 10 days = x
Earning per day =
[By unitary method] (1)
Money spent per day =y (2)
We know that

i.e. Subtract (2) from (1), we get

Hence, the expression to determine how many pesos he saved per day will be:-

Answer:
39 inches
Step-by-step explanation:
5x+x=234
6x=234
234/6=39
x=39 inches
Answer:
Option (C)
Step-by-step explanation:
Given inequalities are,
81 > x and x > 68
Therefore, 81 > x > 68 is the inequality representing the solution area for x.
Out of x = 88, 85 and 80,
x = 80 will lie between the range of x = 68 and x = 81.
Therefore, Option (C) will be the correct option.
There are 9 kennels.
(# of dogs) = 3 (# of kennels)
27 = 3 (# of kennels)
27 / 3 = (# of kennels)
9 = (# of kennels)
Answer:
x = 25
Step-by-step explanation:
Assuming Angle A, B and C are angles in a triangle.
∠A + ∠B + ∠C = 180º
(2x - 20) + (120) + (x + 5) = 180
2x - 20 + 120 + x + 5 = 180
3x + 105 = 180
3x = 75
x = 25
