Answer:
240 minutes or 4 hours
Step-by-step explanation:
So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes.
If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.
Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.
So you have 45/80 and 45/120.
Now add both fractions by finding the lowest common denominator which is 240.
135/240 + 90/240 = 225/240
So Mack did the remaining 15/240.
Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.
Then multiply
15 x 16 = 240
so it would take him 240 minutes or 2 hours.
We have been given a table of values of a function. We are asked to determine whether the given function is linear or nonlinear.
We know that a function is linear when its rate of change (slope) is constant.
Let us find slope for each of the given points using slope formula.
Similarly, we will find the slopes using other given coordinates.
Since the rate of change for each set of points is 
, so the rate of change is constant.
Therefore, the given function is linear.
Well there must be a shape labelled A on a graph which u have to reflect in to y=-x section
I believe the answer to your problem is x=1.25
You will want to get rid of the fraction so you multiply both sides of the equation by 2 and so you'd get
4+2(8x+11)-12=34 then you distribute
4+16x+22-12=34 then combine like terms
16x+14=34 and then move over 14
16x=20and then divide and isolate x
x=1.25
Answer:
247 = j - 285
Step-by-step explanation:
Anything that is labeled with "is" will be what the entire equation is equal to. (Also because the instructions are asking for an equation which is equal to something). Also, fewer than is the subtraction of two things. In this case it will be 285 and j. In the end the equation will be:
247 = j - 285
Hope this helped.
