If it is 50 pages in an hour, half an hour would be 25 pages, and if it is 40 pages in an hour it would be 20 pages in half an hour, the answer is 5 pages more in half hour
Answer:
x - 135
Step-by-step explanation:
Bailey withdrew $135 from her checking account
Withdrew means to subtract
Let's call the amount of money in her checking account x
Algebraic expression to represent situation:
x - 135
Hope this helps :)
Answer:
4th option
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (2, 12) and (x₂, y₂ ) = (6, 6) ← 2 points on the line
m = = = -
the line crosses the y- axis at (0, 15 ) ⇒ c = 15
y = - x + 15 ← approximate equation of line of best fit
Answer:
2
Step-by-step explanation:
In general, .
So we have here that:
We went by itself first.
Subtract 441 on both sides:
Multiply both sides by -1:
Take the square root of boht sides:
So both 2 and -2 would satisfy the equation.
Only one of these is a whole number.
The whole numbers consist of the elements that you can count with and 0.
The whole number set is {0,1,2,3,4,5,6,7,...}
So 2 is the answer.
Check:
Replace x with 2:
437=(21+2)(21-2)
437=(23)(19)
437=437 is a true equation so 2 is definitely a solution.
