Solve:
7w+5=3w -15 please help

w=−5

Step-by-step explanation:

Step 1: Subtract 3w from both sides.

7w+5−3w=3w−15−3w

4w+5=−15

Step 2: Subtract 5 from both sides.

4w+5−5=−15−5

4w=−20

Step 3: Divide both sides by 4.

4w4=−204

w=−5

Hope this helps.

282 6/7 cm^2

step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
