The order of operations says:
P arentheses
E xponents
M ultiplication
D ivision
A ddition
S ubtraction
So first we will do 3 x 9 = 27. (27 - 6 + 3 / 10)
Next do 3/10 = .3. (27 - 6 + .3)
Then solve 27-6 = 21. (21 + .3)
Lastly do the last part! The answer is 21.3, hope this helps!
Answer:
the equation is 10x+50=120
the rate of change is 10x (time)
the initial value is 50
the total value is 50
he will need to save for 7 weeks
Step-by-step explanation:
first you convert to slope intercept form
3x+y = 5 is the same as y = -3x+5
x - 4y = 32 is the same as y = 4x-8
then you graph
(starting with the y-intercepts as your first points)
the point where the two lines intercept is your solution.
