Answer:
a = 5
Step-by-step explanation:
If it's easier for you, you can replace n(a) with y and put a as x.
Now the equation is y = 7x + 4.
It asks you to put in 39 as y.
39 = 7x + 4.
To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.
35 = 7x
Now divide both sides by 7 and we're done!
5 = x
Answer:
Y=10x-250
Step-by-step explanation:
We can treat this problem like we are attempting to graph a line from 2 points (hopefully you know how to do that)
the two points are (40,150)(55,300)
Sally types faster than sue per minute by 10 words. If you divide 3000 by 60 because there are 60 minutes in an hour you will get how many words she types a minute which would be 50.
If Alana pays $125/mo toward an insurance plan that costs $565/mo then her employer must be paying the difference = 565-125 = 440/mo.For the full year of 12 months then her employer pays = 12*440 = $5280.
