The cost of a school banquet is $85 plus $12 for each person attending. Write an equation that gives the total cost of the number of people attending.
A. Y=85x-12
B. Y=12x+85
C. Y=85x+12
D. Y=12x-85
Answer: I think that the answer is B
Step-by-step explanation:
John is twice as old as Mary. The sum of their ages is 21. How old is Mary?
Let J = John's age and M = Mary's age. Select the system equations that represents the problem.
J - 2M = 0
J = M + 2
M - 2J = 0
J + M = 21
Answer:
Mary is 7
Step-by-step explanation:
If their ages combined equals 21 and john is twice Mary’s age then johns age takes up 2/3 of 21. that would b 14. 14 is 2 x 7. and Mary is 7. 14+7=21. Mary is 7 years old
Correct answers are:
J + M = 21
J - 2M = 0
The area of a square is (9x2 − 12x + 4) square units. Determine the length of each side of the square by factoring the area expression completely
Step-by-step explanation:
9x2 − 12x + 4 = 18 - 12x + 4 = 22 - 12x = 2(11 - 6x)
length of 1 side = ± sqrt 2(11-6x) (rej neg value)
What is the slope of y=-3x - 2?*
Answer:
-3!
Step-by-step explanation:
The slope is always listed right before the x in any slope-intercept form. It can be negative or positive, or even a fraction. In this case, it's -3!
I really hope this helps!
Answer:
-3 is the slope
Step-by-step explanation:
y = mx + b.
The variable m represents the slope. So, what ever number replaces the variable m(-3) is the slope.

A dressmaker needs to cut 6-inch pieces of ribbon from rolls of ribbon that are 9 feet in length. How many 6-inch pieces can the dressmaker cut from 15 of these rolls of ribbon? Before you try that problem, answer the question below. How many inches of ribbon does the dressmaker have, in total?
Answer:
Step-by-step explanation:
Answer:
60 pieces
Step-by-step explanation:
What we know:
There are 12 inches in a foot
There are 5 6-feet lengths of ribbon
So, we simply need to multiply.
Since there are 12 inches in a foot, and we only need 6 inches for each one, we can see that she makes 2 pieces for each foot.
Multiply
2*6=12
She makes 12 pieces for each length of ribbon.
Now multiply it by 5
12*5= 60
She can make 60 pieces from 5 of these length of ribbon.
Hope this helps!
which situation could be represented by the equation 15.5 = x/2
Answer:
C. Julie drive 15.5 miles from her home to the grocery store. Julie drives the same path going back home. What is x, the total amount of miles traveled to the grocery store and back home?
Step-by-step explanation:
The situation in the 3rd option represents the equation, 15.5 = x/2.
Distance driven by Julie to the grocery store = 15.5 miles
Distance driven by Julie back home following the same path = 15.5 miles
Total amount of miles travelled to and fro the store, x, = 2*15.5
This means, the mile's covered going to the store or coming back home can be expressed as ½ the total amount of miles, x, covered. Which is: 15.5 = ½x
Therefore, the third option represents the equation, 15.5 = x/2.

The ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2 . The store has 90 BMX bikes . How many mountain bikes does the store have ?
Answer: 60
Step-by-step explanation:
From the question, we are informed that the ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2 and that the store has 90 BMX bikes .
To calculate the number of mountain bikes that the store has goes thus:
= 2/3 × 90
= 2 × 30
= 60 mountain bikes

A local business charges $20 to set up their sweatshirt printing machine with the design and $9.75 in materials per sweatshirt to print.
Write an equation for the average cost A(x) of printing x sweatshirts through this company. A(x)=?
Describe what happens to the average cost per sweatshirts as more and more are printed.
i need help
Given :
A local business charges $20 to set up their sweatshirt printing machine with the design and $9.75 in materials per sweatshirt to print.
To Find :
Write an equation for the average cost A(x) of printing x sweatshirts through this company.
Solution :
Let, number of sweatshirts sold are x.
So, average cost A(x) of printing is given by :
A(x) = 9.75x + 20
Therefore, average cost per sweatshirts are A(x) = 9.75x + 20 .
Hence, this is the required solution.

How can ΔABC be mapped to ΔXYZ? First, translate vertex A to vertex . Next, ΔABC to align the sides a
The correct answer is vertex B to vertex Y
What is transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
Given are two triangles ABC and XYZ.
We have AB = XY = 25 cm, AC = YZ = 29 cm
and also angle A = angle X = 36 degrees
Thus, we find that corresponding congruent sides are
AB and AC with angles A and X
To map ABC onto XYZ,
Vertex B to Y, side AB to side XY with AC coinciding with XZ
Now all vertices x, y, z will perfectly match with transformed ABC
Hence, The correct answer is vertex B to vertex Y

The sum of ten consecutive whole even numbers is 1190
Answer:In other words, since even numbers are the multiples of 22, we can represent an even integer nn by 2k2k, where kk is also an integer. So if we have the even integers 1010 and 1616, we can rewrite them asn=2k→10=2(5)
n = 2k\, \to \,\,16 = 2\left( 8 \right)\,n=2k→16=2(8)
Step-by-step explanation:
Consecutive Even Integers
The best way to illustrate what consecutive even integers are through the use of examples. Observe that any pair of two consecutive even integers are 22 units apart. In other words, if you pick any even integer in the set of consecutive even integers then subtract it by the previous one, you will always get the difference of \bold{+2}+2 or simply \bold{2}2, written without the \bold{+}+ symbol.
