Answer:
26) x = 4
Step-by-step explanation:
26)
20x + 5 + 24x - 1 = 180
20x + 24x = 180 + 1 - 5
44x = 176
x = 176/44
x = 4
If your looking to solve for x, x= -6.
So which is equivilentpemdas
(8-6x+12)(20-6x)multiply/distribute1/4(20-6x)5-6/4x=5-3/2x=-3/2x+5
the answer is D
so mean is equivilent to average
per minute means x feet for every one minute=xfeet/1miin=x/1
so just divide -378/7=-54
mean change in altitude-54 feet per minute
