Find each difference
(- 13n ) - ( 17 - 5n)
Answers
(-13n) + -1(17 + -5n) = 0
(-13n) + (17 * -1 + -5n * -1) = 0
(-13n) + (-17 + 5n) = 0
Reorder the terms:
-17 + (-13n) + 5n = 0
Combine like terms: (-13n) + 5n = -8n
-17 + -8n = 0
Solving
-17 + -8n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '17' to each side of the equation.
-17 + 17 + -8n = 0 + 17
Combine like terms: -17 + 17 = 0
0 + -8n = 0 + 17
-8n = 0 + 17
Combine like terms: 0 + 17 = 17
-8n = 17
Divide each side by '-8'.
n = -2.125

A supermarket sells orange juice in three sizes. The 32 fl oz container costs $1.99,the 64 fl oz container costs $3.69, and the 96 fl oz container costs $5.85. Which size orange juice has the lowest price per fluid ounce? Explain!
Answers
Answer:
64 fl oz
Step-by-step explanation:
To find the best price you take the cost and divide it by the number of fluid ounces ($1.99/32). For the 32 oz it costs .062, for the 64 oz it costs .057, and for the 96 oz it costs .060 (these are all approximate number btw). Therefore, since 64 oz has the lowest number it has the lowest price per fluid oz.

Actually Welcome to the Concept of the ratio and proportion.
here, we clearly notice, that,
4 cups have 2 ounces each, that is
=> 4×2 = 8 ounces
also, 1 cup with 3 ounces,
=> 1×3 = 3 ounces,
adding both we get as,
8+3 = 11 ounces,
the total is 11 ounces.

For what value of k does kx + 7y = 10 have a slope of 3?
Answers
Answer:
k = -21
Step-by-step explanation:
Slope y-intercept form : y = mx +c
kx + 7y = 10
7y = -kx + 10
y = [tex]\frac{-k}{7}x+\frac{10}{7}[/tex]
[tex]\frac{-k}{7}=3\\\\ -k = 3*7\\\\ -k = 21\\\\ k = -21[/tex]

_________________________________
Hint :
[tex]slope = The \: \: coefficient \: \: of \: \: x \: \: in \: \: the \: \: slope-intercept \: \: form \\ [/tex]
_________________________________
Thus we need to find the slope-intercept form of the line which must be like this :
[tex]y = ax + b[/tex]
Let's do it...[tex]7y + kx = 10[/tex]
Subtract sides kx
[tex]7y + kx - kx = 10 - kx[/tex]
[tex]7y = 10 - kx[/tex]
[tex] 7y = - kx + 10[/tex]
Divide sides by 7
[tex] \frac{7y}{7} = \frac{ - kx + 10}{7} \\ [/tex]
[tex]y = \frac{ - kx}{7} + \frac{10}{7} \\ [/tex]
[tex]y = - \frac{k}{7} x + \frac{10}{7} \\ [/tex]
This is the slope-intercept form .
[tex]The \: \: coefficient \: \: of \: \: x = - \frac{k}{7} \\ [/tex]
The slope is 3 ,
Thus :
[tex] - \frac{k}{7} = 3 \\ [/tex]
Multiply sides by 7
[tex]7 \times ( - \frac{k}{7}) = 7 \times 3 \\ [/tex]
[tex] - k = 21[/tex]
Multiply sides by - 1
[tex] ( - 1) \times ( - k) = ( - 1) \times (21)[/tex]
[tex]k = - 21[/tex]

Answers
Answer:
$300
Step-by-step explanation:
10% converted into a decimal is 0.10.
To find 10% of 3,000, you would multiply them.
3,000 times 0.10 is 300.
Therefore, Nora spends $300 a month on clothes.

Kareem is a software salesman. His base salary is $2200, and he makes an additional $60 for every copy of Math is Fun he sells.
Let P represent his total pay (in dollars), and let N represent the number of copies of Math is Fun he sells. Write an equation relating P to N. Then use this
equation to find his total pay if he sells 26 copies of Math is Fun.
Answers
Answer:
Step-by-step explanation:
a. p=2200+60n
b. p=2200+60(26)
p=2200 plus 1560
p=3760
The equation that should be related P to N should be considered as the 2200+60n.
And, the total pay when he sells 26 copies of Math is Fun should be 3760.
Calculation of the equation & the total pay:Since
His base salary is $2200, and he makes an additional $60 for every copy of Math is Fun he sells.
Here P means the total pay
So, here the equation be p=2200+60n
Now the total pay be
p=2200+60(26)
= 2,200 + 1,560
= 3,760
hence, The equation that should be related P to N should be considered as the 2200+60n.
And, the total pay when he sells 26 copies of Math is Fun should be 3760.

The height of an object thrown straight up from a height 5 feet above the ground is given by the equation h(t) =-16t^2 +42t +5, where is the time in seconds after the object is thrown. Find the average speed of the object from 1.5 to 2.25 seconds.
Answers
Answer:
The average speed of the object is 18.67 ft/s.
Step-by-step explanation:
Given;
height function, f(t) = -16t² + 42t + 5
The average speed is given by ;
[tex]v = \frac{dx}{dt} \\\\h(t) = -16t^2+42t+5\\\\h(1.5)= -16(1.5)^2 + 42(1.5)+5 = 32 \ ft\\\\[/tex]
from 1.5 s to 2.25 s = 0.75 s,
[tex]h(0.75)= -16(0.75)^2 + 42(0.75)+5 = 27.5 \ ft[/tex]
[tex]h(2.25)= 27.5 +(-16(2.25)^2 + 42(2.25)+5) \\\\h(2.25) = 27.5 + 18.5 = 46 \ ft[/tex]
The average speed is given by ;
[tex]v = \frac{h(2.25) - h(1.5)}{2.25-1.5}\\\\v = \frac{46-32}{0.75}\\\\v = 18.67 \ ft/s[/tex]
Therefore, the average speed of the object is 18.67 ft/s.

Making the assumption of no compounding interest, suppose you purchase a perpetuity bond from Sense/Net Corporation for $4,000 with an annual coupon rate of 3% . Specify all answers to the nearest dollar, and assume a discount rate equal to that of the current interest rate. What is the yearly return on your $4,000 investment?
Answers
Answer:
$120
Explanation:
Data provided as per the given question below:-
Investment = $4,000
Coupon rate in percentage = 3%
The computation of yearly return is shown below:-
Yearly return = Investment × Coupon rate in percentage
= $4,000 × 3%
= $120
Therefore for computing the yearly return we simply investment with coupon rate in percentage.

Subtract 44 on both sides:
44-44+45x=179-42
45x=137
Divide 45 on both sides:
