2.)What costs the least per bag? A or B?
A: 20 bags for $6.00
B: 32 bags for $9.92
Guys I need the answer super fast please help giving allot of points
Answers
Answer:
Option A
Step-by-step explanation:
Bag A: 30 cents per bag
Bag B: 31 cents per bag
In order to find Cents per bag divide the number of bags from the amount it costs.
Bag A: 6 ÷ 20 = 0.30
Bag B: 9.92 ÷ 32 = 0.31
Answer:
B
Step-by-step explanation:
I say B cost the least per bag. I divided 32 by 9.92 and 20 by 6. That gives me the answers to what each bag costs. bag A costs 3.34 for each bag and bag B costs 3.22. So bag B is cheaper.
Graph the equation
y-3=-3/2(x+4)
Answers
Answer: x = (-2,0) y = (0,-3) slope is -3/2
Step-by-step explanation: graph the line by using the slope and y intercept
The graph for the points (0, -3) and (2, -6) is plotted on the graph below.
The given equation is y-3= -3/2(x+4).
What is the graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.
Graph the line using the slope and y-intercept, or two points.
Slope: -3/2
y-intercept: (0, -3)
Plot the points (0, -3) and (2, -6) on the graph
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s): (−2,0)
y-intercept(s): (0,−3)
Therefore, the graph for the points (0, -3) and (2, -6) is plotted on the graph below.

Solve 3q - 5 = 13 for q.
Answers
⇒ Answer:
[tex]q = 6[/tex]
⇒ Step-by-step explanation:
Lets solve!
[tex]3q -5 = 13[/tex]
⇒ First we add 5 to both sides.
[tex]3q -5 = 13[/tex]
[tex]+ 5[/tex] [tex]+ 5[/tex]
[tex]3q = 18[/tex]
⇒ Next we divide both sides by 3.
[tex]\frac{3q}{3} = \frac{18}{3}[/tex]
[tex]q = 6[/tex]
⇒Woohoo! Brainliest Appreciated! Hope I helped!
Answer:
q = 6
Step-by-step explanation:
To solve for q, isolate the variable.
3q - 5 = 13
Move -5 to the right side and perform the inverse operation. Since you were subtracting on the left, add on the right.
3q = 13 + 5
3q = 18
The last step is to isolate the variable by dividing 3 by 18. The reason you divide on the right is because you were multiplying on the left, and you need to perform the inverse operation.
q = [tex]\frac{18}{3}[/tex]
q = 6
Samantha buys $128 worth of goods at a 25% discount. If the sales tax rate is 6.4%, what is the total amount she will pay?
Answers
Answer:
To do this, you need to find the amount of discount of the original price. To find a percent of a number you first convert the percent to a decimal (i.e. 25% = 0.25). Then you multiply this decimal by the original price. Therefore, the sale price is $17.21. If example.
Step-by-step explanation:
Answer:
102.144
Step-by-step explanation:
128 times 0.25 = 32
128 - 32 = 96
96 times 1.064 = 102.144

Samuel can type nearly 40 words per minute. Use this information to find the number of hours it would take him to type 3.4 × 105 words. Samuel can type 3.4 × 105 words in hours and minutes.
Answers
Answer:
8.925 minutes or 0.14875 hours..?
Step-by-step explanation:
I feel like I'm missing something here... The 3.4 x 105 words seems off. Why didn't they just say 357 words?
Assuming that he types 40 WPM and they're looking for how long it would take for him to type 357 words:
[tex]3.4*105 = 357[/tex] words total
[tex]\frac{357}{40} = 8.925[/tex] minutes
[tex]\frac{8.925}{60} = 0.14875[/tex] hours

Find the equation of the linear function represented by the table below in slope-intercept form.
Answers
Answer:
y= 8x +7
Step-by-step explanation:
slope-intercept form:
y= mx +c, where m is the gradient (or slope) and c is the y-intercept.
Since it is a linear function, the gradient of any 2 points would be equal.
[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]
Thus, gradient of the line
[tex] = \frac{39 - 23}{4 - 2} \\ = \frac{16}{2} \\ = 8[/tex]
Subst. m=8 into the equation:
y= 8x +c
To find the value of c, substitute a pair of coordinates.
When x=0, y= 7,
7= 8(0) +c
c= 7
Thus, the equation of the linear function is y= 8x +7.
