Answer:
x = -1/2 = -0.5
Step-by-step explanation:
2x + 29 >= 28
2x >= 28-29
x = -1/2
Answer:
11.4 mixture:26 and 2/3
7.8 mixture: 53 and 1/3
Step-by-step explanation: Sorry if this is hard to underestand. This is my first answer. This is a RSM question that has been checked.
11.4+7.8=9
x+80-x=80
Multiply
11.4x+624-7.8x=720
3.6x=96
1.2=32
0.6x=16
6x=160
x=26 2/3
80-26 2/3= 53 1.3
Answer:
1 x 4 x 12 = 48
Step-by-step explanation:
48 subs
Speed of Tim = 60 miles/hour
Speed of Joe = 45 miles/ hour
Distance = Speed x Time
A 3 hours, Tim had travelled 60 x 3 miles = 180 miles.
At 3 hours, Joe had travelled 45 x 3 miles = 135.
The difference between the distances is 45.
Therefore, they were 45 miles apart after 3 hours.
I hope this is right.
the x intercept is (12,0) and the y is (0,-8)
