Step-by-step explanation:
l = 3 + 2w
P= 2w t 2l
= 2w+2(3+2w)
=2w+6+4w
=6w+6 = 54
6w=48
w=8
divide 6 both side
l=3+2(8)=3+16=19

Choose 1 answer:
Answer:it’s c or 3/6
Step-by-step explanation:
Answer:
C. y = 3/6x
Step-by-step explanation:
The number by the x is the constant of proportionality. 3/6 is the same thing as 1/2, because when you divide the numerator and denominator by 3 it equals to 1/2.

A certain test is scored by adding 1 point for
each correct answer and subtracting 1/4 of a
point for each incorrect answer. If Jan answered
31 questions correctly and 9 questions incor-
rectly, what was her score?
a. 28 3/4
b. 28 1/4
c. 26
d. 22 1/4
Answer:
A
Step-by-step explanation:
31 correcct answers gives her 31 points, then you subtract 9/4 for the 9 incorrect answers to get twenty eight and 3/4
Solve the following system of equations using substitution, showing all work.
y=2x+3
2x+5y=3
x=negative 1
y=1
showing my work Substitute y=2x+3y=2x+3 into 2x+5y=32x+5y=3.
12x+15=312x+15=3
2 Solve for xx in 12x+15=312x+15=3.
x=-1x=−1
3 Substitute x=-1x=−1 into y=2x+3y=2x+3.
y=1y=1
Answer:
x= -1
y= 1
Step-by-step explanation:
since y=2x+3; plug into other equation
2x+5(2x+3)=3
(distribute 5 to 2x+3)
2x+10x+15=3
(add like terms)
12x= -12
divide by 12 to get x alone
x=-1
now you cand plug in x to either equation to solve for y, but plug into the first equation to make it easier.
y=2(-1)+3
y=-2+3
y=1

7. Robert poys for his family to go bowling. He pays an initial fee
to rent shoes for everyone and then pays a certain amount
per game that his family plays as shown in the graph
How much did Robert pay to rent shoes for
everyone
Total Cost
What was the cost per game at the
bowling alley?
c. Write an equation to represent the situation
Number of Gomes
Answer:
a)Robert pay $12 to rent shoes for everyone
b)Cost of each game is 4.5
c)y = 4.5x+12
Step-by-step explanation:
Refer the attached graph
a)How much did Robert pay to rent shoes for everyone ?
y - intercept will give the rent shoes for everyone
y intercept is point where the graph of a function or relation intersects the y -axis of the coordinate system.
So, from the graph we can see that at x = 0 , y = 12
So, from the graph we can see that the no. of games is 0 . So, Total cost is 12
Thus Robert pay $12 to rent shoes for everyone
b)What was the cost per game at the bowling alley?
So, we are supposed to find the slope
Two pints from graph :
[tex](x_1,y_1)=(0,12)(x_2,y_2)=(2,21)m = \frac{y_2-y_1}{x_2-x_1}=\frac{21-12}{2-0}=4.5[/tex]
So, Cost of each game is 4.5
c)Write an equation to represent the situation Number of Gomes
General equation : y = mx+c
So, y = 4.5x+12
There are 207 students in the 9 classes
at east middle. At this rate, how many students are in 6 classes ? use the radio table below to help you determine you answer
to find the rate first we divide the number of students by the number if classes as follows 207 ÷ 9 = 23 student in each class Then we multiply this rate by the number of classes to get 23 students × 6 classes = 138 students in 6 classes

The formula for the volume of a rectangular prism is V = lwh. Which is the equivalent equation solved for h?
Answer:
V /(lw) = h
Step-by-step explanation:
V = lwh
Divide each side by lw
V/ ( lw) = lwh/(lw)
V /(lw) = h
V /(lw) = h
V = lwh
Divide each side by lw
V/ ( lw) = lwh/(lw)
V /(lw) = h

Answer:
10. y=the total amount of money
A) y=4m
B) y= 4(5.25)
y= $21
11. y= total amount of money
A) y= 40m + 35
B) y= 40(10) + 35
y= $435
Number 10:
You know five people, you and four friends, are contributing the same amount of money for food. Lets say F = Food and M=Money. Since they are contributing the same amount of money, it would be 5 * m, or 5m. So, F would equal 5m. F=5m.
Part B- You would do the same expression, F=5m, but you would instead plug 5.25 in for m. So, 5.25 times 5 would equal 26.25 dollars.
Number 11:
Part A- Let M equal months. $40 times the number of months + 35 is the total cost, so 40m +35 is the expression.
Part B- Since the total cost is 40 dollars times the number of months + $35, you would multiply 40 * 10, to get 400 dollars over 10 months. Then you would add the $35 fee, so the answer would be $435.

A set of data has a mean of 58 and only one outlier of 92. Which statement about this data set must be true?
The range is 34.
The range is 34.
The mode is equal to the mean.
The mode is equal to the mean.
The mean is greater than the median.
The mean is greater than the median.
The distribution curve is skewed to the right.
Answer:
The correct option is;
The distribution curve is skewed to the right
Step-by-step explanation:
The given parameters are;
The mean = 58
The outlier = 92
Given that the outlier, P, can be found from the following formula, we have;
P > Q₃ + 1.5·IQR = (Q₃ + 1.5 (Q₃ - Q₁)
92 > (Q₃ + 1.5 (Q₃ - Q₁)
Given that mean = 58
Therefore, the IQR, and Q₃ are relatively small compared to the outlier, and the data is skewed, with the more smaller numbers than there are large numbers which makes the distribution curve to be skewed to the right.
