Answer:
35 min
Step-by-step explanation:
given that the total time spent is 140min
and that the time spent reading is x minutes
and also that the time spent doing home work is 2(x+5)
the time spent playing video game is 25
the expression for the total time is given as
total = reading +homework +video game
140=x+2(x+5)+25
solving for x we have
140=x+2x+10+25
140=3x+35
140-35=3x
105=3x
x=105/3
x=35
kenny spent 35 min reading
Time spend for reading is 35 minutes
Given that;
Total number of minutes Kenny have = 140 minutes
Time spend for reading = x
Time spend for homework = 2(x + 5) = 2x + 10
Time spend for games = 25 minutes
Find:
Time spend for reading
Computation:
Total number of minutes Kenny have = Time spend for reading + Time spend for homework + Time spend for games
140 = x + 2x + 10 + 25
3x + 35 = 140
3x = 105
x = 105 / 3
x = 35
So,
Time spend for reading = 35 minutes

The parallelogram pictured below has a perimeter of 129. Find the value of y.
Answer:
y = 2½ = 2.5
Step-by-step explanation:
From the question given above, the following data were obtained:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
The perimeter of a parallelogram can be obtained by using the following formula:
Perimeter = 2(a + b)
Thus, with the above formula, we can obtain the value of y as shown below:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
Perimeter = 2(a + b)
Perimeter = 2a + 2b
129 = 2(10y – 9) + 2(17y + 6)
Clear bracket
129 = 20y – 18 + 34y + 12
Collect like terms
129 + 18 – 12 = 20y + 34y
135 = 54y
Divide both side by the coefficient of y i.e 54
y = 135/54
y = 2½ = 2.5
Thus, the value of y is 2½ or 2.5

Function?
Answer:
The domain of R is {-3,-2,1,-3,0}
The range of R is: {2,1,3}
The relation R is not a function
Step-by-step explanation:
Relations and Functions
We are given the ordered pairs of a relation, let's call it R:
R={(-3, 2), (-2, 2), (1, 2), (-3, 1), (0, 3)}
The domain of R is the set of values that relate to 1 or more elements from the range.
The domain of R is {-3,-2,1,-3,0}
The range of R is: {2,1,3}
Note the value 2 is repeated in the second set, but it's reported only once as part of the Range.
A relation is a function if each element of the domain appears in only one ordered pair, or relates to a single element in the Range.
The relation R is not a function, because the ordered pairs (-3, 2) and (-3, 1)
map the element -3 twice.

Lin-Manuel runs a rare book store. Last year, he earned $35,000 in revenue and had explicit costs of $8,000. Lin-Manuel could have made $29,750 testing information security equipment and received an additional $10,000 if he had used the company's inputs in a different way. Calculate Lin-Manuel's economic profit.
Answer: Economic loss of $12,750
Step-by-step explanation:
Economic profit is calculated by deducting both the implicit and the explicit costs from income.
Explicit cost are the costs of running the business whilst implicit costs are the gains that could have been earned if other alternatives had been embarked on.
Economic profit (loss);
= 35,000 - 8,000 - 29,750 - 10,000
= (12,750)
Jose owes his brother $50. He promises to pay his brother back $5 each week until his debt is paid off. Represent the relationship between the debt, D, and the number of weeks, n, in a algebraic expression.
Answer:
5n=50d
Step-by-step explanation:
If n stands for the number of weeks and he is going to pay $5 per week, then the 5n go together and if the debt is 50, then it goes on the opposite side of the equal sign. I hope this helps!
