Answer: A. 138 times
How?
During that time period there were 23 days so 23 multiplied by the amount of times played per day (6)
You get the answer 138
I'm not positive I know the answer, but I have a feeling that because it's asking that you select all that apply, there is more than just one answer.
x + 3 = 0
-3 + 3 = 0
So yeah, just basically solve them as individual problems. Just do additive inverse for each expression.
Answer:
Barney 145 3 Days 310 Miles
Mary 250 5 Days 600 Miles
A) 3 D + 310 M = 145
B) 5 D + 600 M = 250
Multiplying A) by -5/3
A) -5 D - 516.6666M = -241.66666666
B) 5D + 600M = 250
Adding A) and B)
83.3333 M = 8.3333333333
M = .10 per mile
3 D = 114
Daily Rate = 38 dollars per day
Step-by-step explanation:
In order for two lines to be perpendicular, their slopes must multiply together to equal to negative one
So we do negative one divided by 2/5 to get the slope of the red line
Which is -5/2
To check, we do 2/5 multiplied by -5/2 which equals to -1 so our answer is correct
