Answer:
Alisa practiced for 240 minutes (4 hours). In total, they practiced for 288 minutes (4.8 hours).
Step-by-step explanation:
If James practiced for 48, and Alisa practiced 5 times as long, then we would multiply 48 by 5 (240 minutes).
If we want to find how many minutes in total they practiced, then we would add 240 minutes (Alisa's practice time) and 48 minutes (James' practice time) together, which would equal 288 minutes (4.8 hours).
Equation: y=48+x

Answer:
y = 5x -2
Step-by-step explanation:
The slope is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (8 -3)/(2 -1) = 5
The y-intercept is given by the formula:
b = y -mx
b = 3 -5(1) = -2
Then the slope-intercept form equation is ...
y = mx +b
y = 5x -2 . . . . . . . . using the m and b we found above
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol - includes square roots, cube roots and so forth. Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find.
So √12 is in radical form. I think what you are asking for is to reduce the expression to its simplest radical form.
So 12 = 4*3, √12 = √4 * √3.
We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.
This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.
Answer:
D) 2/4
Step-by-step explanation:
2/4 is equivalent to 4/8 which is less than 5/8
