The answer would be 21/50. If you have numbers with a few zeros you can cross one of the top amd bottom until you reach the other numbers, if that makes sense. You can changd 420/1000 to 42/100. Then just keep dividing it by a numner that goes evenly into both the numerator and denominator.
Answer:
Step-by-step explanation:
Area = side*side
side * side = 49
side * side = 7*7
side = 7 inches
Perimeter = 4*side
=4 * 7
= 28 inches
Answer:
A . x= -16
Step-by-step explanation:
Step-by-step explanation:
normally, if we have the gradient (or slope of inclination or change rate) and a point, we start using the point-slope form :
y - y1 = a(x - x1)
with (x1, y1) being a point on the line, and a being the slope of gradient (or ... however you want to call it).
y - 1 = 2(x - 2) = 2x - 4
y + 3 = 2x
2x - y = 3
Answer: D
Step-by-step explanation:
If f(x) = 4x - 2 and g(x) = 2x + 7 then which of the following gives f(g(3))?
g(3) = 2*3+7 = 6+7 = 13
f(g(3))=f(13) = 4* 13 -2= 52 -2 = 50
