Answer:

Step-by-step explanation:
There were three friends and the total fare was $j
Each of the friends pays
for their cab fare.
Since Angela also paid a $5 Tip
Total Amount Paid by Angela = Share of cab fare + Tip

We can simplify this further by taking the LCM.

The total amount paid by Angela therefore is :
Answer:
Step-by-step explanation:
No solutions....means the lines are parallel...means ur 2 equations have to have the same slope but different y intercepts
y = 2x + 4 and y = 2x + 3
========================
Infinite solutions...means u have the same line
y = 2x + 4 and 2y = 4x + 8....notice how if u reduce the 2nd one by dividing everything by 2 u get y = 2x + 4...same line
========================
1 solution....means ur equations will have different slopes and different y intercepts.
y = 2x + 4 and y = 4x + 2
now, u can pick which one u want :)
Answer:
x>29
Step-by-step explanation:
Multiply each term by -1
-x * -1 < -29 * -1
x > 29
Answer:
2290 steel balls weigh 3,180 grams so each ball weighs 1.3886462882
