Answer:

w = -8

Step-by-step explanation:

  step 1:(20 - 9w) -  4 • (15 - w)  = 0

step 2:   -5w - 40  =   -5 • (w + 8)

 step 3:   -5 • (w + 8)  = 0

 step 4:  Subtract  8  from both sides of the equation :

                     w = -8

20-9w=4(15-w)
20-9w=60-4w
+9w +9w
20 = 60+5w
-60 -60
-40=5w
Divide by 5 on both sides to get w alone.
-8 = w

A fair charges 7.25 for admission and 5.50 for a ride pass. Ten friends visited the fair. Not all of the friends purchased ride
Free_Kalibri [48]
7.25(10) + 5.50p = 105.50
72.50 + 5.50p = 105.50
5.50p = 105.50 - 72.50
5.50p = 33
p = 33 / 5.50
p = 6 <=== there were 6 ride passes purchased

write the standard form of the line that is parallel to 2 x + 3 y = 4 and passes through the point (1, -4).
jolli1 [7]

Answer:

  2x +3y = -10

Step-by-step explanation:

The given line equation is in standard form, so the one we write will match that form. A parallel line will have the same x- and y-coefficients, but a different constant on the right.

Put the point values in the left-side expression to find the required right-side constant: (x, y) = (1, -4)

  2(1) +3(-4) = constant = 2-12 = -10

Your line is ...

  2x +3y = -10
