in order to buy a $38 pair of shoes, you have to borrow $16 from your friend. How much money did you start with
A-$22
B$22
C$54
D-$54
Please Help
Answer:
22 dollars
Step-by-step explanation:
38 - 16 = 22
if they cost 38 subtract the amount you borrowed(16) and you get what you started with(22)
Answer:
B 22
Step-by-step explanation:
You'll put x since you don't know how much the person started with then you do plus 16.
x+16=38
Subtract 16 both sides.
x=22
Which polynomial can be factored using the binomial theorem?
x2 + 20x + 400
x2 + 45x + 225
x3 – 18x2 + 108x - 36
x3 + 21x2 + 147x + 343
Answer:
Step-by-step explanation:
I think the one you want is the last one, but I've never called it that.
21x^2 + 147x + x^3 + 343
x^3 + 343 is a cubic binomial. It factors into (x + 7) (x^2 - 7x + 49)
21x(x + 7) + (x + 7)(x^2 - 7x + 49)
(x + 7) [ 21x - 7x + x^2 + 49)
(x + 7) [x^2 + 14x + 49]
(x + 7) ( x+7)^2
(x + 7)^3
It's the only answer that does factor. There must be a simpler way of doing it, but this will give you the right answer.
Can anyone help me with this
Answer and Step-by-step explanation:
This graph is a One to One Function.
For a function to be one-to-one, each x value must have its own y-value, which is the case for this graph.
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If you draw a vertical line on the graph, and it intersects more than once, then the graph does not define as a function because that x value has more than one output (y).

The ratio of qualified teachers to unqualified teachers is 1;2. Use the given ratio and determine how many qualified teachers there are if there are 540 unqualified teachers. show your calculations
Answer:
270
Step-by-step explanation:
by using the proportion rule:
let X be the number of qualified teachers then
1:2=X=540 i.e.
1/2 = X/540
by cross multiplication,
540x1=2xX
540=2X i.e.
X=540/2
X=270
There are 270 qualified teachers.
To solve this, we would apply the knowledge of proportion.
It is simply a way of stating that two ratios are of equal measure.
For example, [tex]a:b = x:y[/tex] or [tex]\frac{a}{b} = \frac{x}{y}[/tex]
Applying the following proportion rule given that:
Ratio of qualified teachers to unqualified teachers is 1:2.
Number of unqualified teachers = 540
Let number of qualified teachers be represented by x.
Therefore:
[tex]\frac{1}{2} = \frac{x}{540}[/tex]
Cross multiply
[tex]2x = 540(1)[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} = \frac{540}{2} \\x = 270[/tex]
Therefore, the number of qualified teachers is 270.

A corn refining company produces corn gluten
cattle feed at a variable cost of $82 per ton. If fixed costs are $120,000 per month and the feed sells for $134 per ton, how many tons must be sold each month for the company to have a monthly profit of $560,000?
With explaining pleaseee:)
The amount of tons that must be sold each month for the company to have a monthly profit is 13,076.923 tons per month
Let x represent the amount of tons sold each month
Hence,
560,000=134x-(82x+120,000)
Remove the bracket
560,000=134x-82x-120,000
560,000=52x-120,000
52x=560,000+120,000
52x=680,000
Divide both side by 52
x=680,000/52
x=13,076.923 tons per month
Inconclusion The amount of tons that must be sold each month for the company to have a monthly profit is 13,076.923 tons per month.

What is -1 7/8 + -2 1/4? Please explain why and a step by step :).
9514 1404 393
Answer:
-4 1/8
Step-by-step explanation:
Many people find it easier to factor out -1, then do the addition. The fractions need a common denominator before they can be added. A suitable denominator that is a multiple of both 4 and 8 is 8.
The fraction 1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8.
__
So, the problem can be rewritten as ...
-(1 7/8 +2 2/8)
= -((1+2) +(7/8 +2/8))
= -(3 +9/8)
The fraction 9/8 is an improper fraction equal to 8/8 +1/8 = 1 1/8. Then the sum is ...
-(3 +1 1/8) = -4 1/8
