Answer:
If we have 8 * x + y + y:
We have to first substitute in x and y where they should be:
=> 8 * 9 + 10 + 10
According to the order of operations(PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction, multiplication and division is you go from left to right order, and same with addition and subtraction.)), we do the multiplication first(8*9):
=> 72 + 10 + 10
Now we just add them up:
=> 92

A triangle with a base of 4 centimeters and height of 3.5 centimeters. She found the area of the enlarged triangle. Her work is shown below. One-half (4) (3.5) (5) = 35 centimeters squared What was Beth's error? She should have divided One-half (4) (3.5) by 5. She should have divided One-half (4) (3.5) by 5 squared. She should have multiplied (4) (3.5) by 5. She should have multiplied One-half (4) (3.5) by 5 squared.
Answer: She should have multiplied One-half (4) (3.5) by 5 squared.
Step-by-step explanation:
The calculation of Beth is wrong. Since Beth enlarged the triangle below by a scale of 5, she should find the area of the traingle and then multiply by 5².
This will be:
= 1/2 × 4 × 3.5 × 5²
= 2 × 3.5 × 25
= 175cm²

Answer:
The answer is Distributive Property
Step by Step:
Your given equation is 7(w+6)+4
You are distributing 7 to w to get 7w, and 7 to 6, to get 42. The plus 4 stays the same because you don't have anything to distribute.
Addition, is obviously wrong, does 7 + 6 = 42? Multiplication is wrong. Sure you might be multiplying, but you are distributing to both numbers. And Commutative is DEFINITY wrong, because it has nothing to do with this situation

What is the slip of the line?
Answer:
slope m = 2
Step-by-step explanation:
to find the slope you have to pick two points in the line
(x1,y1) = (2,1)
(x2,y2) = (3,3)
And the equation for slope is
m = (y2-y1)/(x2-x1)
m = (3 - 1) / (3-2) = 2

At a local fitness center, members pay a $10 membership fee and $4 for each aerobics class.
Nonmembers pay $5 for each aerobics class. For what number of aerobics classes will the cost for
members and nonmembers be the same?
Qu
Thus, for aerobics classes, the cost will be the same for members and nonmembers.
(Type a whole number.)
Answer:
If both the members and nonmembers take 5 aerobics classes, they will have paid the same amount of money.
Step-by-step explanation:
To solve this problem, we can create a chart:
Step One: Where x equals the number of aerobics classes,
Members Nonmembers
Cost in Dollars 10+3x 0+5x
Step Two: We create an equation to solve for x.
Member Cost=Nonmember Cost
10+3x= 0+5x
Step Three: Solve for x:
10+3x= 5x Subtract 3 from both sides
10=5x-3x Combine like terms
10=2x
5=x
∴For five aerobics classes, the cost of members and nonmembers will be the same.

Of the girls on the Alden Middle School soccer team, % also play on a travel team. How many of the girls on the middle school team also play on a travel team?
Answer:
The question is incomplete, so I looked for similar ones and found:
Of the 25 girls on the Alden Middle School soccer team, 40% also play on a travel team. How many of the girls on the middle school team also play on a travel team?
we can solve this the following way:
25 girls on the soccer team x 40% that play on a travel team = 10 girls form the soccer team that play on a travel team
we can also multiply (25 girls x 40) / 100 = 10 girls
we can check our work by:
10 girls / 40% = 25 girls in total
A line contains the points (4,4) and (5,2). What is the equation of the line
that contains these two points?
Answer:y=-2/1x+12
Step-by-step explanation:
To find slope you need to use slope formula (y2-y1)/(x2-x1)
(2-4)/(5-4)
-2/1 is our slope
Now we need the y-int
Y=-2/1x+b
Take one of the given points and apply it to our equation
2=-2/1(5)+b
2=-10/1+b
2=-10+b
Add 10 to each side
12=b
Our final equation is
y=-2/1x+12
2+2(-3)(7) is the answer negative?

The sum of 28 consecutive odd positive integers is a perfect cube. Determine the smallest possible set? What is the first and last terms in the sequence. Plz helppp!
Answer:
71 + 73 + ..... + 125 = 2,744 = [tex]14^{3}[/tex].
Step-by-step explanation:
The smallest set starts at 71. The last term is 125.
The total is 2,744, which is [tex]14^{3}[/tex].
The smallest possible set is 71,73,75,....125. The first and last terms in the sequence is 71 and 125 respectively.
What is airthmatic sequence?Geometric sequence is the sequence in which the next term is obtained by adding or substracting the previous term with the same number for the whole series.
The sumation of airthmatic sequence is find out using the following formula.
[tex]S=\dfrac{n}{2}(a+l)[/tex]
Here, (a) is the first term of the sequence, (l) is the last term and (n) is the number of terms in sequence.
Let x is the first and the smallest term of the set. This set consists 28 consecutive odd positive integers. Thus, the sum of this set will be,
[tex]\sum=x+(x+2)+(x+4)+...+(x+54)\\\sum=28x+(2+4+6+....+54)\\\sum=28x+[\dfrac{27}{2}(2+54)]\\\sum=28x+756\\\sum=28(x+27)\\\sum=2\times2\times7(x+27)[/tex]
Now here 7 is prime number. The value of (x+27) should be perfect square of 7 and 2 to make it perfect cube. thus,
[tex]x+27=7^2\times2\\x=98-27\\x=71[/tex]
Put this value to find the sequence as,
[tex]71,71+2,71+4......,71+34\\71,73,75,.......125[/tex]
The first term in this set is 71 and last term is 125.
Hence, the smallest possible set is 71,73,75,....125. The first and last terms in the sequence is 71 and 125 respectively.
