Answer:
w = -20
Step-by-step explanation:
-[tex]\frac{w}{5}[/tex] + 9 = 13
Shift the (+9) to the other side of the equation. (+9) will turn into (-9).
-[tex]\frac{w}{5}[/tex] = 13 - 9
= 4
Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).
-w = 4 × 5
= 20
Multiply both sides of the equation by (-1) so that -w will turn into w.
w = (-1) × 20
w = -20

Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of practice weeks = 5
Number of practice days in a week = 5
The total number of practice days.
= 5 x 5
= 25 days
Total time for 25 practice days = 37.5 hours.
The number of hours each practice day.
= 37.5 ÷ 25
= 1.5 hours

Answer:
a. rad27
Step-by-step explanation:
we can use a2+b2=c2 where c is the hypotonuse.
we plug in 3^2+b2=6^2
9+b^2=36
b^2=27
then do a rad over each to get rid of the ^2 on the b
b=rad 27

Angle a is 5/3 of Angle b.
Find Angles a and b plz
Answer:
Angle a = 112.5°
Angle b = 67.5°
Step-by-step explanation:
Angle a + angle b = 180° (Supplementary Angles/angles on a straight line)
Let x = m<b
m<a = ⁵/3(x)
Therefore:
⁵/3x + x = 180
[tex] \frac{5x}{3} + x = 180 [/tex]
[tex] \frac{5x + 3x}{3} = 180 [/tex]
[tex] \frac{8x}{3} = 180 [/tex]
Multiply both sides by 3
[tex] \frac{8x}{3} \times 3 = 180 \times 3 [/tex]
[tex] 8x = 540 [/tex]
Divide both sides by 8
x = 67.5°
Angle a = ⁵/3(x) = ⁵/3(67.5) = 112.5°
Angle b = x = 67.5°

segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
Answer:
YZ is located at Y (0, 1) and Z (-2, 1) and is one-third the size of Y'Z'.
Step-by-step explanation:
Since Y'Z' was dilated from the origin at a scale factor of 3, you can divide its X and Y coordinates by 3 to find the coordinates of YZ.
The statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.
What is dilation?The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.
The question is incomplete.
The complete question is:
Segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
segment YZ is located at Y (0, 9) and Z (−18, 9) and is three times the size of segment Y prime Z prime.segment YZ is located at Y (0, 3) and Z (−6, 3) and is the same size as segment Y prime Z prime.segment YZ is located at Y (0, 1.5) and Z (−3, 1.5) and is one-half the size of segment Y prime Z prime.segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime.As we know, in the dilation image of the two-dimensional figure can be larger or smaller depending on the dilation factor.
We have:
segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3).
After dilation:
Y (0, 1) and Z (−2, 1)
Thus, the statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.
