Ed signed up for a weight-loss program. The table shows his weight in pounds of the terms of the number of weeks since he began
il63 [147K]
Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2

y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week

Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week

when they started, Ed weighed 205 lbs and Eric weighed 200 lbs

* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.

Noah started to solve the equation –4.6p – 6.3p + 3.9 = –9.18 below. Combine like terms: –10.9p + 3.9 = –9.18 Apply the next ste
irinina [24]

Answer:

The next steps are to:

1) subtract 3.9 from both sides

2) divide both sides by -10.9

3) p = 1.2

Step-by-step explanation:

To solve a multi-step equation, you need to first combine like terms, which was done for your to get the equation:  -10.9p + 3.9 = -9.18.  At this point, you have a two-step equation where you need to use inverse (opposite) operations to isolate the variable.  Whatever you do to one side of the equation, you do to the other:

1) -10.9p + 3.9 - 3.9 = -9.18 - 3.19 or -10.9p = -13.08

2) -10.9p/-10.9 = -13.08/-10.9

3) p = 1.2
