Between emma and dave, we have 7/10ths of the money
3x + 2x = 7/10
5x = 7/10
x=(7/10)/5
x= 14/100
Dave will get 28/100 or 7/25ths
Check : 30/100 Colin
42/100 Emma
+ 28/100 Dave

Two consecutive odd integers have a sum of 48 . find the integers.
Two consecutive odd integers:
2x+1, 2x+3
Two consecutive odd integers have a sum of 48
2x+1+2x+3=48
find the integers:
Solve for x
2x+1+2x+3=48
4x+4=48
4x+4-4=48-4
4x=44
4/4x=44/4
x=11
sub in x=11
2x+1, 2x+3
2(11)+1, 2(11)+3
22+1, 22+3
23,25
Check: 23+25=48
23 and 25 are two consecutive odd numbers that have a sum of 48
Answer:
-1/2
Step-by-step explanation:
You mention a graph, but have not shared that graph. However, your presentation of two points on this line is sufficient for the calculation of the slope of the line joining the two points.
The points are (-2, 2) and (0, 1).
As we move from (-2, 2) to (0, 1), x increases by 2 and y decreases by 1.
Hence, the slope of this line is m = rise / run = -1/2.
