The discount is $1,880 and the selling price is $21,620, make sure to put the dollar sign to make sure you know what the number means
For the first question, the total is 240 so that goes in front of the equals sign. he has already worked 97 hours, so the expression on the right begins with 97 and adds the unknown number of hours, <em>h</em>, to it:
240 = 97 + <em /><em>h</em>
For the second question, there is no graph so I cannot answer it.
3rd question: no image, can't answer.
4th question:
Use a factor tree:
240
/ \
10*24
/\ /\
5*2 *8*3
/ / /\ \
5 * 2 *4*2 *3
/ / /\ \ \
5 * 2 *2*2 * 2 * 3
Starting with the smallest factor and using exponents we have
Area = l•w
length= 2x+1 width= x
210 = (2x+1)(x)
distribute x
210 = 2x^2 + x
move 210 to other side
2x^2+x-210 = 0
factor the polynomial
(2^x2+21x)-(20x-210)=0
x(2x+21)-10(2x+21)=0
(x-10)(2x+21)=0
x=10, -21/2
measurements can’t be negative so x=10
the width is 10
the length is 2(10)+1=21
Answer:
x=28 or C
Step-by-step explanation:
The graph shows a right angle which is 90 degrees
This means that the two angles seperated by line C added together will get 90 degrees.
That means the formula will be 2x+1+33=90
With that shown we can get rid of A and B
Next step is to add 33 and 1 together
This gives us 2x+34=90
Then we will move 34 to the other side by subtracting giving us 2x=90-34
Then we will subtract 90-34 which will get us 56
The equation is now 2x=56
The last step is to devide 2 from each side
This lets us get the answer x=28
Hope this helps!
