Answer:
The cost of the lessons taken
Step-by-step explanation:
Let
y -----> the total paid for the baseball bat and the lessons
c ----> the number of lessons
we have
y=25c+75
This is a linear equation in slope intercept form
y=mx+b
where
b=$75 -----> the price of he baseball bat (y-intercept)
m=25 $/lesson ----> the slope of the linear equation
therefore
25c represent the cost of the lessons taken
Answer:
b is the answer
Step-by-step explanation:
f(x) = ax^2 + bx + c
Answer:
6+n/8=2
Step-by-step explanation:
* More Than = (+) or in some cases (>)
* Quotient of a (#) = Any letter that represents a number, so in this case "n", because we do not know that number yet. We divide this with "8" because it says "and 8".
* Equal = <---
Answer:
8 units
Step-by-step explanation:
b(14)/2 = 56
14b = 112
b = 8 units
Answer:
60 miles per hour
Step-by-step explanation:
Consider the structure of the wording: "miles per hour"
The word "per" means for each. There is you clue.
Each is, one of and one of is unit measurement
So the controlling element in this question is that you need to convert the 3 hours into 1 hour.
Using ratio properties
180
3
=
x
miles
1
hour
We need to 'force' the left hand side into the same form as the right. That is: we need to convert the denominator into 1 and see what happens to the numerator.
⇒
180
÷
3
3
÷
3
=
x
1
⇒
60

=

So the unit rate of speed is
60
miles
