Answer:
well let’s break this down
Let’s make type a coffee “a”
And type b coffee “b”
a is 4.35
b is 5.70
We knwo that b is twice as many as a
The total is 614.25
So we can do soemthing like this
4.35a+ (5.70b)2 = 614.25
Now solve
If we simplify its really
4.35a+11.40b =614.25
I like multiply by a 100 to get rid of decimals
435a+1140b=61425
Here we can go 2 ways
We can isoalte a or b
im gonna isloate b
so it would be (61425-435a)/1140 =b
Now we can use that as a subsitube to find a
Now we can just do this
435a +1140(61425-435a)/1140 = 61425
Pop it through an algebra calculator (just search up math pa..Pa and copy paste it, edit if needed) and then you’d get your answer
If you would like to solve -6 > -30 - 4x for x, you can do this using the following steps:
-6 > -30 - 4x
4x > -30 + 6
4x > -24 /4
x > -24/4
x > -6
The correct result would be x > -6.
