Unit rate is how many units of work can you do in 1 unit of time
3 and 3/5=3+3/5=15/5+3/5=18/5
(18/5mi)/40mins
divide by 40
aka times 1/40
(18/5)(1/40)=18/200=9/100=0.9/10=0.09/1
0.09 miles per minute
Answer:
C) Maria bought a magazine for $8 and 2 notebooks. She spent a total of $15. What was the cost of each notebook?
Step-by-step explanation:
The equation has twice an unknown value added to 8 with the result being 15.
<em>Here are how the answer choices compare to the equation:</em>
A) only one magazine of unknown cost is involved, not two. There is not enough information to answer this question with any equation.
B) three unknowns are involved and the question asks for the difference of their sum and 15. There is not enough information to answer this question with any equation.
C) if x represents the cost of the notebook, the equation is appropropriate to finding its cost, as asked by the question. This is the best choice.
D) only one unknown. The question makes no sense, as she bought items worth more than the amount paid.
6 pounds will cost $17.88
If you set up a proportion like this: 7.45/2.5=?/6, then all you have to do is cross multiply. 6x7.45 is 44.7, then 44.7 divided by 2.5 is 17.88
Answer:
1st : neither linear nor nonlinear
2nd: nonlinear
3rd: linear
4th: both linear and nonlinear
Answer:
-3
Step-by-step explanation:
to find slope (m), use the following equation:
m = (y₂ - y₁)/(x₂ - x₁)
Solve. Note that:
(x₁ , y₁) = (3 , 5)
(x₂ , y₂) = (2 , 8)
Plug in the corresponding numbers to the corresponding variables.
m = (8 - 5)/(2 - 3)
Simplify.
m = (3)/(-1)
m= -3
-3 is your slope (Rise 3, Run -1 => remember that the answer is (rise/run) => (3/-1))
