Answer:
Step-by-step explanation:
2) a(a + b) + b(a - b) - 2ab / a² - b²
= a² + ab + ab - b² - 2ab / a² - b²
= a² - b² / a² - b²
= 1
3) [x - 1/(x - 1)(x - 2)] + [x - 2/(x -2)(x - 3)]
= (1 / x - 2) + (1 / x - 3)
= x - 3 + x - 2 / (x - 2)(x - 3)
= 2x - 5 / x² - 5x + 6

I have a problem in math. I have to figure out how to tell their similar through scale factor, to prove their similar, I don't know what that is, I'm stuck. Then I have to explain why c = 60 degrees (see image).
Answers
Answer:
see explanation
Step-by-step explanation:
If the ratios of the 3 pairs of corresponding sides of the 2 triangles are equal , then the triangles are similar (SSS postulate )
the3 ratios of the 2 triangles , left to right are all equal to
[tex]\frac{3}{4}[/tex]
Then the triangles are similar by the SSS postulate
the corresponding angles of similar triangles are congruent, then
∠ c = 60°
Also both triangles have 3 congruent sides and are therefore equilateral triangles with all angles equal to 60°, so
c = 60°

sylvie needs $110 for a concert ticket. she already has $ 16 and she can earn the rest by working 10 hours at her job. if h represents her hourly earnings. select all the equations that can be solved to find sylvies hourly earnings
Answers
Given, Sylvie needs $110 for a concert ticket.
Sylvie has $16.
Her hourly earnings = $h
Sylvie is working 10 hours at her job.
She is getting in 1 hour = $h
So, 10 hours she will get = $ = $
So the total amount she has now = $16 + $(10h) = $()
So we can write the equation as,
110=16+10h
We can move 16 to the left side also. 16 is added to the right side. We can move it by using reverse operation of addition. Reverse operation of addition is subtraction. So we will subtract 16 from both sides. Subtracting 16 we will get,
110-16=16+10h-16
110-16=10h
We have got the required answer.
To find Sylvie's hourly income the correct options are option A and option D.
Sylvie needs 110
She Already Have 16
10 Per Hour
110 ÷ 10 = 11
She Will Got 110 If she Work 11 hours
110 - 16 = 94 ÷ 11 = 8

110 Concert Ticket

Step-by-step explanation:
so we first have to find the ummmm the slope intercept form for the graph
sooo we must get two points and use the equation y2 - y1/ x2 - x1
(4,15) and (6, 31)
31 - 15/ 6 - 4
16/2
8
sooo rn its:
y = 8x + b
now to find the y-intercept we have to input a point we did NOT use yet.
(8, 47)
47 = 8(8) + b
47 = 64 + b
b = 47 - 64
b = -17
the equation for the table is
y = 8x - 17
soo the y-interecept is when x is 0 so we have to use the equation y2 - y1/ x2 - x1 to find the distance
sooo
(0, 17) [for the table] and (0, 2) [from the equation y = 7x + 2)
17 - 2/0-0
15/0

Solve for v: -19v = -133
Answers
Answer:
v=7
Step-by-step explanation:
[tex]-19v=-133\\v=\frac{-133}{-19}\\ v=7[/tex]
Hope this helps!
edit:
When -19v = -133, you have to get v alone.
This means you have to remove the -19 from the front of the v
To do this, you divide by the -19(the coefficent)
When you divide, you must divide from both sides, and thus you will get:
[tex]v=\frac{-133}{-19}[/tex]
The negative signs cancel out, and result in [tex]\frac{133}{19}[/tex]
From there, you just calculate it and you get 7.

While Mike was visiting his sister in Arlington, he bought an aquarium that was marked down 60% from an original price of $100. If the sales tax in Arlington is 5%, what was the total cost of the aquarium?
Answers
Answer:
63
Step-by-step explanation:
60% of $100 is just %60 and 5% of 60 is 3 so, 60 + 3 = $63
Answer:
$45
Step-by-step explanation:
So, first we would find 60% of the $100
100 x .60 = 60
(When finding the amount of a percentage we move the decimal over twice)
then subtract what we got from the original price to find what he paid before tax:
100 - 60 = 40
Now we find 5% of $100:
100 x .05 = 5
Finally, we add this to what he was paying before taxes:
40 + 5 = 45, so $45
