Answer:
80
Step-by-step explanation:
Simply reverse the steps.
In the end he has 60, before that he got 20 dollars for cutting grass, so subtract 20.
Now he has 40, which is after he spent half of his money on games, so multiply it by 2.

Teresa has a total of 13 coins.
None of them are pennies, and she has at least three each of quarters, dimes, and nickels.
What is the least amount of money she can have?
Answer: $0.65
Step-by-step explanation:
She can have all nickels since at least 3 nickels means that there is a possibility that all 13 of her coins are nickels.
100 cents=1 dollar
Nickel=5 cents
5 cents * 1 dollar/100 cents=
5*1/100=0.05 dollars
Hence, the least total amount of money she could have is:
13*0.05=$0.65
This is equivalent to 140 cents.
==========================================================
Explanation:
"she has at least three each of quarters, dimes, and nickels"
Let's say she has exactly 3 of each for now
3 quarters = 3*25 = 75 cents3 dimes = 3*10 = 30 cents3 nickels = 3*5 = 15 centsSo far she has 75+30+15 = 120 cents (aka $1.20) with the 3*3 = 9 coins mentioned. There are 13-9 = 4 coins remaining
To achieve the least money possible, those missing four coins must be the smallest denomination allowed, i.e. the nickel. We can't go for penny since it states "none of them are pennies". So we add 4*5 = 20 more cents onto 120 to get 120+20 = 140 cents aka $1.40
A truck driver is driving on an interstate and is about 150 miles from his planned exit. He is traveling at a speed of 50 miles per hour and plans to stop for a rest within 30 miles of the exit on either side. Find the minimum and maximum numbers of hours the truck driver will drive before stoping for a rest.
The minimum and maximum numbers of hours the truck driver will drive before stoping for a rest will be 3.6 hours and 2.4 hours respectively.
How to illustrate the information?From the information, the truck driver is driving on an interstate and is about 150 miles from his planned exit and he is traveling at a speed of 50 miles per hour and plans to stop for a rest within 30 miles of the exit on either side.
Therefore, the appropriate equation be:
50h - 150 = 30
50h = 30 + 150
50h = 180
Divide
h = 180 / 50
h = 3.6 hours.
The minimum hours will be:
50h = 150 - 30
50h = 120
h = 120/50
h = 2.4 hours.

Determin whether the relation defines a function, and give the domain and range.
The relation is not a function if its domain is on the x-axis and its range is on the y-axis. However, if the relation's domain is on the y-axis and its range is on the x-axis, it is a function.
If so, what kind of function is it?
Relationships are defined by three factors:
1. domain is a set of inputs.
2. an output set referred to as range.
3 . relationships between domain and range-related items.
If and only if each element of the domain is associated to just one member of the range, is a relation a function. It must be noted that the solution may vary based on the domain and range that we assume.
The provided relation is a function if the x-axis is the range and the y-axis is the domain, as opposed to when the x-axis is the domain and the y-axis is the range.

what is the value of the algebraic expression if x=1/2, y -1, and z=2?
The value of the given algebraic expression 6x(y²z) is (D) 6.
What are algebraic expressions?In mathematics, an algebraic expression is an expression composed of variables and constants as well as algebraic operations (addition, subtraction, etc.). Terms combine to form expressions. 2(x + 8y) is an algebraic expression, for example.So, substitute the values of x, y, and z in the given expression:
6x(y²z)
When x = 0.5, y = -1 and z = 2
= 6(0.5)((-1)²)(2)= 3(1)(2)= 6Therefore, the value of the given algebraic expression is (D) 6.

Answer: -3b + 21
Step-by-step explanation:
-3(b-7) distribute the -3 to the rest of the equation
= -3b + 21
Answer:
Step-by-step explanation:
So we have our equation -3(b-7)
We are multiplying -3 by b, and by 7, and subtracting the products from each other
so, -3x7=-21
and we would have -3b
so now, we can put this back into the equation as
-3b+21 (because the rule is that subtracting a negative from a negative is the same as adding a positive)

The length of a rectangel is 11 less than 9 times the width. The perimeter of the rectangle is 18 inches
According to the question, the given parameters has relationship between the length and the width of the rectangle.
The perimeter of the rectangle is 18 inches.
Now, using standard perimeter as well as area formulas of a rectangle. Therefore, the equation can become:
Let us assume, the width of the rectangle be 'w' inches
The length of a rectangle be (9w - 11)
As we know, perimeter of a rectangle is 2(l + w)
Substitute the calculated parameters in the perimeter formula:
18 = 2(9w - 11 + w)
⇒ 9 + 11 =10w
⇒ w = 2 inches and l = 7 inches
Then, the calculated width is 2 inches and length is 7 inches.

The sum of two numbers is 14 . One number is 2 less than the other. Find the numbers.
The two numbers are 6 and 8.
What are the two numbers?The first step is to determine the simultaneous equations that would be used to determine the answer. The simultaneous equations would be derived from the information provided in the question.
x + y = 14 equation 1
x - y = 2 equation 2
Where:
x = larger number
y = smaller number
The simultaneous equations would be solved using the elimination method
Now, subtract equation 2 from equation 1
2y = 12
Divide both sides of the equation by 2
y = 12 / 2
y = 6
Substitute for y in equation 2
x - 6 = 2
Add 6 to both sides of the equation
