Answer:$240.00
Step-by-step explanation:
$240.00
Answer:
It depends on how much the computer costs originally and the model of computer.
Step-by-step explanation:
Say the computer costs 151.98 USD with the tax added, then the computer would cost 148.00 USD without tax. Or if the computer costs 162.79 USD with the tx added, then the computer would cost 160.00 USD without tax. It's the same for the rest but it also depends on the model of computer. (My calculations of adding 3 or 2 USD as the tax is just for example, i don't know how they calculate tax for computers)
151.98-148.00= 3.98$
162.79-160.00=2.79$

Find the sum of the first 47 terms of the following series, to the nearest integer.
13, 18, 23, ...
Answer:
The sum of the first 47 terms of the given series = 6016
Step-by-step explanation:
Given the sequence
13, 18, 23, ...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]18-13=5,\:\quad \:23-18=5[/tex]
As the difference between all the adjacent terms is the same.
so
[tex]d=5[/tex]
[tex]a_1=13[/tex]
Arithmetic sequence sum formula
[tex]n\left(a_1+\frac{d\left(n-1\right)}{2}\right)[/tex]
Put the values
[tex]d=5[/tex]
[tex]a_1=13[/tex]
[tex]n=47[/tex]
[tex]=47\left(13+\frac{5\left(47-1\right)}{2}\right)[/tex]
[tex]=47\left(13+\frac{5\left(47-1\right)}{2}\right)[/tex]
[tex]=47\left(13+115\right)[/tex]
[tex]=47\cdot \:128[/tex]
[tex]=6016[/tex]
Thus, the sum of the first 47 terms of the given series = 6016

Jina is saving money to buy a bike. She has $63 and is going to save an additional $9 each week. The bike costs $198. In how many weeks will she have
enough money to buy the bike?
(a) Write an equation that could be used to answer the question above.
First, choose the appropriate form. Then, fill in the blanks with the
numbers 63, 9, and 198. Let w represent the number of weeks.
Answer:
Jina will have enough money to buy the bike in 15 weeks
Step-by-step explanation:
y = mx + b
198 = 9x + 63
Subtract 63 from both sides;
135 = 9x
Divide both sides by 9;
x = 15

Jen and Kamlee are walking to school. After 20 minutes, Jen has walked 45 mile. After 25 minutes, Kamlee has walked 56 mile. Find their speeds in miles per hour. Enter the correct answers in the boxes.
Answer:
Jen's speed = 135 miles per hour (Approx)
Kamlee's speed = 134 miles per hour (Approx)
Step-by-step explanation:
Given:
Jen walk = 45 miles
Jen's time = 20 min = 20/60 = 0.333 hour
Kamlee walk = 56 miles
Kamlee's time = 25 min = 25/60 = 0.416667 hour
Find:
Speed
Computation:
Jen's speed = 45 / 0.333
Jen's speed = 135 miles per hour (Approx)
Kamlee's speed = 56 / 0.416667
Kamlee's speed = 134 miles per hour (Approx)

Answer: It is .............. A or C but I can't see the question you're trying to answer
Step-by-step explanation:
Factorise completely
a) ( 2 + 2 + 2) a) 9a(x – 3b ) - 4 (x – 3b)
b) 5a(2b – 3 ) - 4 (2b – 3)
c) x( 2h-k )+ 3y ( k – 2h )
Answer:
a) 9a(x - 3b) - 4(x - 3b) = (9a - 4)(x - 3b)
b) 5a(2b - 3) - 4(2b - 3) = (5a - 4)(2b - 3)
c) x(2h - k) + 3y(k - 2h)
= x(2h - k) - 3y(2h - k)
= (x - 3y)(2h - k)
Step-by-step explanation:
Answer:
a) (9a-4)(x-3b)
b) (5a-4)(2b-3)
c) (x-3y)(2h-k)
Step-by-step explanation:
9a(x – 3b ) - 4 (x – 3b) = (9a-4)(x-3b)
Since both 9a and -4 are multiplied by (x-3b), they can be put in a bracket too.
5a(2b – 3 ) - 4 (2b – 3) = (5a-4)(2b-3)
Since both 5a and -4 are multiplied by (2b-3), they can be put in a bracket too.
x( 2h-k )+ 3y ( k – 2h ) = x(2h-k) - 3y (-k + 2h)
We can multiply + 3y ( k – 2h ) by (-1) to switch up the arithmetic operations.
x(2h-k) - 3y (-k + 2h) = x(2h-k) -3y(2h-k)
Since both x and -3y are multiplied by (2h-k), they can be put in a bracket too.
x(2h-k) -3y(2h-k) = (x-3y)(2h-k)

Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works. 28. __________ If the number of pizzas varies directly with minutes, how many pizzas can Allan make in 3 hours?
Answer:
96 pizzas
Step-by-step explanation:
First, we have to determine how many pizza he can make in one minute = 8/15 = 0.533
Convert 3 hours to minutes = 3 x 60 = 180 minutes
The number of pizzas he would make in 3 hours = 180 x 0.533 = 96 pizzas

Learning task 2
A. Solve the systems of equations by a) graphing b) elimination c) substitution
Eq. 1: 2x - 3y = -1; Eq. 2: y = x - 1
B. Solve the problem using any method.
The sum of two numbers is 32 and the difference is 2. Find the numbers
The given equations are
[tex]2x-3y=-1\cdots(i) \\\\y=x-1\cdots(ii)[/tex]
(a) Solution by graphing both the equations:
Graph for both the equations (i) and (ii) are in the figure. The point of intersection of both the graph is the solution of the equations.
From the graph, the point of intersection is (4,3)).
Hence, the required solution is (4,3).
(b) Solution by elimination method:
Equations (ii) can be written as -x+y=-1, now multiply it by 2, we have
[tex]-2x+2y=-2\cdots(iii)[/tex]
Add equations (i) and (iii), we have
2x-3y=-1
-2x+2y=-2
__________
[tex]\Rightarrow -3y+2y=-1-2\\\\ \Rightarrow -y=-3\\\\ \Rightarrow y=3.[/tex]
Putting the value of y=3 in equation (i), we have
[tex]2x-3\times 3=-1 \\\\\Rightarrow 2x=-1+9=8 \\\\\Rightarrow x=8/2=4[/tex]
Hence, the required solution is (4,4).
(c) Solution by substitution method:
Substituting the value of y from equation (ii) to equation (i), we have
[tex]2x-3(x-1)=-1 \\\\\Rightarrow 2x-3x+3=-1 \\\\\Rightarrow -x=-1-4=-4 \\\\\Rightarrow x=4[/tex]
Putting the value of x=4 in equation (i), we have
[tex]y=4-1=3[/tex].
Hence, the required solution is (4,3).

whats the percent increase from $6 to $66
Answer:
6 x 1100% = $66
Step-by-step explanation:
How many solutions does the equation below have.
*The answer choices are below*
==========================================
Work Shown:
2(b+3)-17 = 3b-7+b
2b+6-17 = 4b-7
2b-11 = 4b-7
-11+7 = 4b-2b
-4 = 2b
2b = -4
b = -4/2
b = -2
There is one solution and it is b = -2
A quick way to tell we have one solution is to note that both sides are a linear expression, and that the slopes of each linear expression are different values. If you had two lines with the same slope, then you'd have either parallel lines or coinciding lines (leading to no solutions and infinitely many solutions respectively). When you have two lines with two different slopes, then they are guaranteed to intersect only once. That intersection point is the solution.
Answer:
The answer is one solution
Step-by-step explanation:
1)2(b+3)-17 = 3b-7+b
2)2b+6-17 = 4b-7
3)2b-11 = 4b-7
4)-11+7 = 4b-2b
5)-4 = 2b
6)2b = -4
7)b = -4/2
Final your answer is b = -2
