Answer:
He brought 34 cookies to the fundraiser.
Step-by-step explanation:
1.25x + 25 = 67.50
1.25x = 67.50 - 25
1.25x = 42.50
x = 42.50/1.25
x = 34
Answer:
34 cookies in total.
Step-by-step explanation:
Well if he is selling cookies for $1.25 each and has a starter of 25$, we can already mark off 25$ from $67.50. Now it's just simple division, so 42.50/1.25 is 34 cookies being sold.
The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Write an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x). Show or explain how you found your equation.
Answer:
y = 9x/5 + 50
Step-by-step explanation:
We are represent the information as coordinate (x,y)
If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)
Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;
(150, 320)
Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope;
m = y2-y1/x2-x1
m = 320-230/150-100
m = 90/50
m = 9/5
Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c
230 = 9/5(100)+c
230 = 9(20)+c
230 = 180 + c
c = 230-180
c = 50
Get the required equation
y = mx+c
y = 9/5 x + 50
Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50

Solve for x.
21x – 4

Answer:Think x is 3
Step-by-step explanation:
Enter the value for x that makes the equation 1/2 (4x – 8) + 3x = 36 true.
Answer:
x = 8
Step-by-step explanation:
1/2(4x – 8) + 3x = 36
~Simplify left side
2x - 4 + 3x = 36
~Combine like terms
5x - 4 = 36
~Add 4 to both sides
5x = 40
~Divide 5 to both sides
x = 8

The value of angle APA' is 90°.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have a point 'p' which is a fixed point.
Triangle ABC is rotated about the 'p' point such that the new location of A, B, and C becomes A', B', and C'.
The new triangle formed is triangle A'B'C'.
From the figure, we can clearly see that the angle APA' is a right-angle triangle.
m∠APA' = 90°
Thus, the value of angle APA' is 90°.

Step-by-step explanation:
Please answer!!!!!!!
To see if it is possible, you will want to create an equation.
3(4x+2) = 6(2x+2)
As you can see, you will need to use the distributive property for this equation.
12x + 6 = 12x + 12
Remove 6 from both sides.
12x = 12x + 6
Divide 12 by both sides
x = x + 0.5
Because the answer wasn't x = x, the two plants won't ever be the same height. Even if you tried to subtract 0.5, you'd only get a negative 0.5 on the other side.

the metal bar/random line is almost the same size as the other two sides of the triangle. if one side is 32ft, then the opposite side is 32ft also. the bottom is 100ft, so we could eliminate C. because it couldnt be that number. now the bottom triangle, one side is 40ft so the other side has to be 40ft as well. its asking about the metal bar.
its either:
A. 53.2ft or
B. 44.4
because the line is almost the same size as 32ft. its almost a equallateral triangle. i would go with A. though because if you imagine the line at the bottom of the line (100ft.) the line would go over half of it (and 53.2 is over half of 100) so i would say
A.53.2

The owner where your work explains that you're paid $8/hour and receives a $25 bonus each month for being the manager. If the owner hands you a check for $250, How many hours did you work this month? Write an equation and solve.
Answer:
28.125 hours
Step-by-step explanation:
Amount of money paid per hour = $8
Bonus of being a manager = $25
Total amount of money paid = $250
To find:
Number of hours worked for this month?
Solution:
Let the number of hours worked = [tex]h[/tex] hours
Amount of money paid for [tex]h[/tex] hours = $8[tex]h[/tex]
As per question statement:
Bonus + Amount of money paid for [tex]h[/tex] hours = $250
[tex]25 + 8h = 250\\\Rightarrow 8h = 250 -25\\\Rightarrow 8h = 225\\\Rightarrow h =\dfrac{225}{8}\\\Rightarrow \bold{h = 28.125\ hours}[/tex]
Therefore, the answer is:
Number of hours worked = 28.125 hours

Daniel can spend no more than $40 at the fair. If admission into the fair is $10 and the rides cost $1.50 each, which inequality represents the greatest number of rides Daniel can go on?
A. 10r + 1.50 ≥ 40
B. 1.50r + 10 ≤ 40
C. 1.50r + 10 <40
D 10r+1.50<40
Explain your reasoning and solve the inequality :
Answer:
B
Step-by-step explanation:
The sum spent has to be either equal to or less than 40. So r many rides, each of them being 1.50, plus 10 dollars has to equal to less or equal to 40 dollars.
Answer:
The answer is B
The greatest number of rides Daniel can go on is 20.
Step-by-step explanation:
Total: The same or less than 40
Fair Admission: 10
ride: 1.50x
40 ≤ 10 + 1.5r
To solve:
40 ≤ 10 + 1.5r
40 - 10 ≤ 10 + 1.5r - 10
30 ≤ 1.5r
30 ÷ 1.5 ≤ 1.5r ÷ 1.5
20 ≤ r
The greatest number of rides Daniel can go on is 20.

The cost of 3 pounds of bananas is $6.57. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of bananas, x ?
A) 6.57
B) 3
C) 2.19
D) Not here
Answer:
It is C.
Step-by-step explanation:
You divided 6.57 by 3
and 3 by 3
3 by 3 = 1
6.57 = 2.19
3 so for every 1 pound it costs $2.19
C) 2.19
