Step-by-step explanation:
2(sp)=ln
6x+2=10x-6
8=4x
x=2
therefore sp=3×2+1=6+1=7
Option D
Answer:
Yes
Step-by-step explanation:
Given that Machine M, working alone at its constant rate, produces x widgets every 4 minutes. Machine N, working alone at its constant rate, produces y widgets every 5 minutes.
When both machines work for 20 minutes
Machine A would produce =
widget and
Machine B would produce =
widgets
So we can say that Machine A would produce more widgets than Machine N at that time.
Answer is Yes
4 friends evenly dividing up a n - slice pizza
So each one get
slices of pizza.
For example, if n = 12 slice then each friend gets 12/4 = 3 pieces. If Harris ate one slice less then he ate
=3 -1 = 2 pieces.
So the general expression for slices of pizza did Harris eat is
