Problema Solution
There were 155 people at the basketball game. Tickets for the game are $2.50 for students and $4 for adults. If the total money received for admission was $492.50, how many students and adults attended the game?
Answer provided by our tutors
let
s = the number of student tickets sold
a = the number of adult tickets sold
there were 155 people at the basketball game
s + a = 155
the total money received for admission was $492.50
2.50s + 4a = 492.50
by solving the system of equations
s + a = 155
2.50s + 4a = 492.50
we find
s = 85 students
a = 70 adults
What is the surface area of a rectangular brick with a length of 12 in, a width of 8 in, and a height of 6 in?
Answer:
We can apply the formula for surface area of a rectangular prism here. i.e.
Step-by-step explanation:
A=2(l×w + h×l + h×w), where l is length, h is height and w is width.
As mentioned above, length = 12 cm, width = 8 cm and height = 6 cm.
Therefore
2(12×7+6×12+6×8)=2(84+72+48)=2(204)=408. So the surface area of the brick is 408 square centimetres.
8.6w+2.2(2w-5)=54

8th grade math
A plant measures 10 cm and increases in height by .02 percent each day, upon conclusion it measures 11.04 cm. What is a reasonable domain to plot the growth function?
Answer:
the correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.
Step-by-step explanation:
I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).
Slope = (20 - 10)/(50 - 30) = 1/2
Write an equation of the line that passes through the given points.
(-1,4) and (4, -1)
The equation is . (Type your answer in slope-intercept form.)
[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{4})\qquad(\stackrel{x_2}{4}~,~\stackrel{y_2}{-1})\\\\\\% slope = m\stackrel{slope}{m}\implies\cfrac{\stackrel{rise}{\stackrel{y_2}{-1}-\stackrel{y1}{4}}}{\underset{run}{\underset{x_2}{4}-\underset{x_1}{(-1)}}}\implies \cfrac{-5}{4+1}\implies \cfrac{-5}{5}\implies -1[/tex]
[tex]\begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-\stackrel{y_1}{4}=\stackrel{m}{-1}[x-\stackrel{x_1}{(-1)}]\\\\\\y-4=-1(x+1)\implies y-4=-x-1\implies \blacktriangleright y = -x+3 \blacktriangleleft[/tex]

Dan has three dogs. He feeds them these amounts of food each day. 1 1/2 cups, 2 1/3 cups, and 3 1/2 cups. Ben has two dogs. He feed them 3 1/4 cups and 4 1/2 cups of dog food per day. Who uses more dog food? How much more?
Answer:
ben
5/12
Step-by-step explanation:
1 1/2+2 1/3+3 1/4 = 22/3 -dan
3 1/4+4 1/2 = 31/4 -ben
ben - dan
31/4-22/3

Kina's mother decided to increase her pocket money by 40%. How much extra did Kina receive each week if previously she had been given J$400 per week?
Answer:
$560
Step-by-step explanation:
10% of $400 is $40. 40% of $400 is 10%x4. 40% of $400 is $160. Since her allowance increased by $160, it is now $560 per week.
$560 - if you `increase $400 by 40% the answer will be $560
Question 7 of 15
Which is an equation of the line through (0,0) and (5,-2)?
A. y = 2
B. y = -x
C. y = -2
D. y = x
... None?
Not A because y = 2 is shown as forever 2 so cannot go through both points.
Not B because y = -x cannot go through (5,-2)
Not C because y = -2 cannot go through (0,0)
Not D because y = x cannot go through (5,2)

Review of Unit 6 Measurement:
Michael bought 42 feet of baseboard trim to put around the edges of his workout
room. He used 39 feet 5 inches, which means he still has 2 feet 7 inches leftover for
another project or to use for a repair, if needed. True or false?
Helpful conversion fact: 1 foot = 12 inches
True
False
Answer:
True
Step-by-step explanation:
Brought - the amount used
42 feet - 39 feet 5 inches.
42 feet 0 inches = 41 feet 12 inches
- 39 feet 5 inches = - 39 feet 5 inches
2 feet 7 inches

Solve the system of equations
−2x+3y=3
−4x+5y=1
Answer:
x= 6, y= 5
Step-by-step explanation:
-2x +3y= 3 -----(1)
-4x +5y= 1 -----(2)
(1) ×2:
-4x +6y= 6 -----(3)
(3) -(2):
-4x +6y -(-4x +5y)= 6 -1
Expand:
-4x +6y +4x -5y= 5
y= 5
Substitute y= 5 into (1):
-2x +3(5)= 3
-2x +15= 3
2x= 15 -3
2x= 12
x= 12 ÷2
x= 6

Solve Each Problem
1) At summer camp the ratio of boys to girls was 8: 5. If there were 32 boys, how many girls were
there?
21. Determine if the values in the table are
Answer:
20 girls.
Step-by-step explanation:
If 32 divided by 8 is 4, then 4x8= 32.
We use this equation to find out how many girls there are. 5x4 equals 20, so there are 20 girls at summer camp.
Explain how to compare decimals. Use the numbers 6.75 and 6.732 to
help you explain this process.
Answer:
6.75>6.732
Step-by-step explanation:
We are given that
6.75 and 6.732
We have to compare two given decimal numbers.
First we convert like decimal number
In 6.75 there are two digits after decimal point.
In 6.732 , there are three digits after decimal point
Therefore, we put zero in 6.75 to convert like decimal number
Now, we get
6.750
Unit place of both decimal numbers are same and tenth place of both decimal number are same.
Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
5 >3
Therefore, 6.750 is greater than 6.732
6.75>6.732
Morwenna rents a truck she pays $20 plus .50 per mile. Let t represent the relationship between the factor. Write an equation that represent the situation.!!!!!
Answer:
50x+20=ur mom
Step-by-step explanation:
Answer:
t = 20 + .50m
m = number of miles travelled
t = total cost
Step-by-step explanation:
t represents the total cost and m represents the number of miles travelled. Since it costs .50 per mile, you would do .50m so that you could calculate the cost based on the number of miles and since the truck at first cost 20 dollars, you would add that to the equation to. This gives you t = 20 + .50m.
