It seems confusing, but it's just breaking down the steps for you. It's done the same as any other word problem.
a. The unknown is how many minutes she used beyond the plan. So, we'll use "m" for the variable, to represent minutes.
b. 73.40 = 65 + 0.10m
The 73.40 is the total, which is why it's by itself. 65 represents the price per month for the plan, and 0.10m is the price per extra minute multiplied by the unknown amount of minutes used.
c. 73.40 = 65 + 0.10m
8.40 = 0.10m
84 = m
d. The number of minutes that Allegra went over the time that the plan allows is found by solving the equation we just wrote and solved. $0.10 is paid for every minute past the plan's allowance, meaning that "m" in the equation, when solved, shows us exactly how many minutes over Allegra went.
#1) x-8= -12
#2) 15+k= 2
#3) x/-7= -20
#4) (5/8)(x)= -20
The / in #2 means to divide and the ( ) mean to multiply
Answer:
See the diagram for understanding
Step-by-step explanation:
Suppose the woman at point A and moves towards east . But the point A is at the south and she is moving upwards towards east according to the compass. That is why this statement is incorrect .
In the compass it would be east but she has to move north to reach east. There's a difference between the actual position the direction of movement of the person to reach that position.
This is better explained by the following diagram.
Now we can see she will move along line B , C and D to reach east which are actually to the north of her position. So the given statement is false.
