Answer:
1.) subtract = 1 1/3 - 3 1/2 = answer
2.) subtract = 6 3/4 - 1 1/2 = answer
3.) add = 3 1/4 + 2 1/8= answer
4.) subtract = 4 3/4 - 2 1/6 = answer
Step-by-step explanation:
5.) 3 lawns = 6 3/4 hrs
1st lawn 2 1/2 hrs
2nd lawn 1 3/4 hrs
add 2 1/2 + 1 3/4 = total
then 6 3/4 hrs - total = the amount it takes to mow the 3rd lawn
im sure u know how to add and subtract fractions is u r in middle school :)
Answer:
Step-by-step explanation:
The equation of any line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
Two points are given: (-6,4) and (-2,2). Calculating the slope:
The equation of the line is, so far:
To calculate the value of b, we use any of the given points, for example (-6,4):
Solving:
b = 1
The equation of the line is:
We can see none of the choices is correct.
The question is asking the lateral surface area of a cylinder with radius 3 in and length 12 in.
A = 2πr*l
.. = 2π*(3 in)*(12 in)
.. = 72π in^2
.. ≈ 226 in^2 . . . . . . . . . . matches selection a)
If the rounding is to the nearest ten, then the greatest one
is 67,404 and the smallest one is 67,395 .
If the rounding is to the nearest hundred, then the greatest one
is 67,449 and the smallest one is 67,950 .
U²-2uv-48v²
u(u-8v)+6v(u-8v)
(u+6v)(u-8v)
