This is slope-intercept form y=mx+b
when you substitute it, it becomes y=6x-3
Answer:
The value of the x is 53.5 or x=53.5
Step-by-step explanation:
Given data in the question:-
We have to find the value of x.
Solution:-
Hence the answer is 53.5
Answer:
Cost of a kit is $20
cost of a microscope is $80
Step-by-step explanation:
Here, we want to write a set of equations and solve
Let the cost of a microscope be $m while the cost of a kit be $k
Total cost of 38 microscopes will be 38 * m = $38m
Total cost of 47 kits = 47 * k = $47k
The sum of these is $3980
That will be;
47k + 38m = 3980 ••••••(i)
A microscope cost 4 times a kit
Mathematically;
m = 4k •••••••••(ii)
Substitute ii into i
47k + 38(4k) = 3980
47k + 152k = 3980
199k = 3980
k = 3980/199
k = $20
Recall;
m = 4k
m = 4 * 20 = $80
I got 37 on my calculator
There is 60 seconds in a minute, so if you have 5.8x10^6 seconds (5800000 by moving the decimal to the right 6 times) divided by 60, gives you <span>96666 minutes or 9.6x10^4</span>
