Make w the subject of Y-aw=2w-1

2 answers:

So you're gonna take add 1 to both sides and add aw to both sides also
y+1=2w+aw
then you factorize the w
y+1=w(2+a)
divide 2+a in both sides
y+1/2+a=w
the answer is
y+1/2+a=w

Answer:

w = \frac{1 + y}{a + 2}

Step-by-step explanation:

collect the term in w together → ( subtract 2w from both sides)

y - aw - 2w = - 1 → ( subtract y from both sides)

- aw - 2w = - 1 - y → ( multiply through by (- 1) )

aw + 2w = 1 + y → ( take out w as a common factor )

w( a + 2)= 1 + y → ( divide both sides by (a + 2 ) )

w=\frac{1+y}{a+2}

Convert the rectangular equation to polar form.

N76 [4]

To convert from rectangular coordinate (x, y) to polar coordinate (r, θ).
r is given by the square root of the sum of the squares of the rectangular coordinate.
$r= \sqrt{x^2+y^2}$
and θ is given by the arctan of the ratio of y to x.
$\theta=\tan^{-1} \frac{y}{x}$
Example:
To convert rectangular coordinate (3, 4) to polar coordinate
$r= \sqrt{3^2+4^2} = \sqrt{9+16} = \sqrt{25} =5 \\ \theta=\tan^{-1}( \frac{4}{3}) =53.13^o$
Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)

Sh. 10,920

Step-by-step explanation:

Since the sales is above sh. 100,000,his commission is (2.4+1.5) 3.9%.

3.9% of 280,000= 10920.

Therefore, his commission is sh. 10,920

The Rodriguez family went to dinner at Pasta Palace. Mr. Rodriguez ordered a meal for $6.25; Mrs. R ordered a meal for $7.50; th

Romashka-Z-Leto [24]

Given:
Mr. Rodriguez : 6.25
Mrs. R 7.50
2 children @ 4.99 each <u> 9.98</u>
Subtotal: 23.73
Sales tax 7.25% 1.72 *23.73 x 7.25%
Total tip 15% <u> 3.56 </u> *23.73 x 15%
Grand total $29.01

Tips should be applied to pre-tax amount not post-tax. However, some companies compute tip based on post-tax amount. This means that the tip you are paying is computed based on the total amount of the meal as well as the sales tax you paid for the meal.

Charlene is a video game designer and wants to make sure that her games can be played on all types of screens. In order for the

Nikitich [7]

Answer:

The playable area has a width of 9 inches and a height of 6 inches.

Step-by-step explanation:

There are a number of ways you can get there.

1. Check the answers to see which have the right area and aspect ratio.

A: area = 24 in² — does not match 54 in²

B: area = 54 in², aspect ratio 6:9 = 2:3 — does not match 3:2 aspect ratio

C: area = 54 in², aspect ratio 9:6 = 3:2 — matches problem statement

D: area = 121.5 in² — does not match 54 in²

2. If the screen were 3:2 (inches), its area would be 6 in². The area of 54 in² is 9 times that value, so the actual screen dimensions are √9 = 3 times 3:2. That is, they are width:height = 9:6 inches — matches selection C.

3. You can write equations for width and height and solve.

w/h = 3/2

wh = 54

Substituting w=3/2·h into the second equation gives

... (3/2)h·h = 54

... h² = 36 . . . . . multiply by 2/3

... h = √36 = 6 . . . . square root, result in inches
