Answer: y=12/20=0.6
Step-by-step explanation:
Rephrase the given equation
1 and 1/5y+3/10y-1/2y=1/3y+2/5
6/5y+3/10y-1/2y=1/3y+2/5
Find the GCF (greatest common factor) and multiply it on both sides
(6/5y+3/10y-1/2y)×30=(1/3y+2/5)×30
36y+9y-15y=10y+12
Add like terms together
30y=10y+12
Subtract 10y on both sides
30y-10y=10y+12-10y
20y=12
Divide 20 on both sides
20y/20=12/20
y=12/20=0.6
Hope this helps!!

The inverse, f'(x), of f(x) =
X + 5
Х
can be written as
5
x-1
a) Find f(2)
b) Find f'(2)
Step-by-step explanation:
Given
[tex]f(x) = \frac{x + 5}{x} [/tex]
So
[tex]f(2) = \frac{2 + 5}{2} \\ = \frac{7}{2} [/tex]
Now
[tex] {f}^{ - 1} (x) = \frac{5}{x - 1} [/tex]
So
[tex] {f}^{ - 1} (2) = \frac{5}{2 - 1} \\ = \frac{5}{ 1} \\ = 5[/tex]

14d - 22 + 5d = 12d - 8
Answer:
d = 2
Step-by-step explanation:
14d - 22 +5d = 12d - 8
19d -22 = 12d - 8
+22 +22
19d = 12d + 14
-12d -12d
7d = 14
/7 /7
d = 2
Answer:
d = 2
Step-by-step explanation:
Simplifying
14d + -22 + 5d = 12d + -8
Reorder the terms:
-22 + 14d + 5d = 12d + -8
Combine like terms: 14d + 5d = 19d
-22 + 19d = 12d + -8
Reorder the terms:
-22 + 19d = -8 + 12d
Solving
-22 + 19d = -8 + 12d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-12d' to each side of the equation.
-22 + 19d + -12d = -8 + 12d + -12d
Combine like terms: 19d + -12d = 7d
-22 + 7d = -8 + 12d + -12d
Combine like terms: 12d + -12d = 0
-22 + 7d = -8 + 0
-22 + 7d = -8
Add '22' to each side of the equation.
-22 + 22 + 7d = -8 + 22
Combine like terms: -22 + 22 = 0
0 + 7d = -8 + 22
7d = -8 + 22
Combine like terms: -8 + 22 = 14
7d = 14
Divide each side by '7'.
d = 2
Simplifying
d = 2

Stacy reasons that since dilations change lengths they also change angles by the same factor. Is she correct? If not, explain why, I will list brainlist if you reply fast
Answer:
Stacy is incorrect. Dilations do not affect the angles of a given figure since dilations create parallel lines and the angles on parallel lines are congruent.

NUMBER: 17 SQUARE: 289 SQUARE ROOT: 4.123
Hope this helps a little.
Answer:
a. 4 and 5
Step-by-step explanation:
We are given 17 squared, and are asked on whether which of it is between the following pairs.
Squaring a number always gives it a smaller number since you are trying to find a number times itself to make the number in the square root.
Therefore by this knowledge, a. would be the most reasonable answer, since 17 is quite a small number, squaring it will equal something smaller.
If 9 garden hoses cost $196.83 and the price of each hose is the same how much does each hose cost?
Answer:21.87
Step-by-step explanation:
196.83 divided by 9
Answer:
They each cost $21.87
Step-by-step explanation:
If each hose costs the same you can just divide the total (196.83) by the number of hoses (9) to get 21.87.
(8x + 9) + (–6x – 1)
Answer:
5
Step-by-step explanation:
Simplifying
(8x + 9) + -1(6x + -1) = 0
Reorder the terms:
(9 + 8x) + -1(6x + -1) = 0
Remove parenthesis around (9 + 8x)
9 + 8x + -1(6x + -1) = 0
Reorder the terms:
9 + 8x + -1(-1 + 6x) = 0
9 + 8x + (-1 * -1 + 6x * -1) = 0
9 + 8x + (1 + -6x) = 0
Reorder the terms:
9 + 1 + 8x + -6x = 0
Combine like terms: 9 + 1 = 10
10 + 8x + -6x = 0
Combine like terms: 8x + -6x = 2x
10 + 2x = 0
Solving
10 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + 2x = 0 + -10
Combine like terms: 10 + -10 = 0
0 + 2x = 0 + -10
2x = 0 + -10
Combine like terms: 0 + -10 = -10
2x = -10
Divide each side by '2'.
x = -5
Simplifying
x = -5

Pls help its my last question?!?!
Answer:
x = -11
m<B = -43
m<C = -22
Step-by-step explanation:
To solve for x, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.
I hope this is correct and helps!

Solve for x. −12x+13>35 Drag and drop a number or symbol into each box to correctly complete the solution.
Answer:
x < -11/6.
Step-by-step explanation:
−12x + 13 > 35
-12x > 35 - 13
-12x > 22
Divide both sides by -12 and invert the inequality sign:
x < -22/12
x < -11/6.

3sin60°+xcos30°.tan45°=xcot30°
Answer:
x = (6[tex]\sqrt{2}[/tex])/(4[tex]\sqrt{2}[/tex] -3)
Step-by-step explanation:
sin60 degree = [tex]\sqrt{3}[/tex] /2
cos30 degree = 1/2
tan 45 degree = sin45 degree / cos45 degree = ([tex]\sqrt{2}[/tex]/2)/([tex]\sqrt{2}[/tex] /2) = 1
cot 30 degree = cos30 / sin30 = ([tex]\sqrt{3}[/tex] /2)/(1/2) = [tex]\sqrt{3}[/tex]
so, let us plug the above values in the given eqution and solve for x
3([tex]\sqrt{3}[/tex] /2 ) + x(1/2) *1 = x([tex]\sqrt{3}[/tex])
3([tex]\sqrt{3}[/tex] /2 ) = x([tex]\sqrt{3}[/tex]) -x(1/2)
3([tex]\sqrt{3}[/tex] /2 ) = x(([tex]\sqrt{3}[/tex])-(1/2)) (by taking x as a common factor)
3([tex]\sqrt{3}[/tex] /2 ) = x(((2[tex]\sqrt{3}[/tex])-(1))/2)) (making the same common denominator
now devide both sides by (((2[tex]\sqrt{3}[/tex])-(1))/2))
x = 3([tex]\sqrt{3}[/tex] /2 ) / (((2[tex]\sqrt{3}[/tex])-(1))/2))
x = 3([tex]\sqrt{3}[/tex] ) / ((2[tex]\sqrt{3}[/tex])-(1))

Answer:
A) AA similarity
Step-by-step explanation:
AA stands for "angle, angle" and means that the triangles have two of their angles equal.
SAS stands for "side, angle, side" and means that we have two triangles where the ratio between two sides is the same as the ratio between another two sides and we we also know the included angles are equal.
SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio.
Here we can easily see that two angles are equal
∠CYK and ∠KZP∠CKY and ∠PKZ (they're cross angles)Therefore it's AA similarity
