Answer: ![\dfrac{x}{10}-y](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B10%7D-y)
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
![\text{Savings = Money earned - Money spent}](https://tex.z-dn.net/?f=%5Ctext%7BSavings%20%3D%20Money%20earned%20-%20Money%20spent%7D)
i.e. Subtract (2) from (1), we get
![\text{Savings = }\dfrac{x}{10}-y](https://tex.z-dn.net/?f=%5Ctext%7BSavings%20%3D%20%7D%5Cdfrac%7Bx%7D%7B10%7D-y)
Hence, the expression to determine how many pesos he saved per day will be:-
![\dfrac{x}{10}-y](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B10%7D-y)
Answer:
25 and 54
Step-by-step explanation:
(a)
6z² - 2z + 5 ← substitute z = 2
= 6(2)² - 2(2) + 5
= 6(4) - 4 + 5
= 24 - 4 + 5
= 20 + 5
= 25
(b)
64 - 5z ← substitute z = 2
= 64 - 5(2)
= 64 - 10
= 54
so heres how you do this
28/7=4 kilograms lost each day
now convert the 4 kilograms to pounds
4 x 2.2 = 8.8 pounds lost each day is your answer

Answer:
C. 1.87
Step-by-step explanation:
3.5x - 2.8 = -4.67x + 12.5
3.5x + 4.67x = 12.5 + 2.5
8.17x = 15.3
x = 15.3 ÷ 8.17
x = 1.87270501836
So, the closest choice to 1.87270501836 is 1.87, so the answer is C.
Hence, the answer would be C. 1.87. I am 100% sure on this, for I am a pro.
