Answer:2(4*7)
this is an expression
Step-by-step explanation:
if you want to solve it
you would multiply 4 by 7 which gives you 28
then double 28
you would multiply 28 by 2
which then gives you an answer of 56
Answer:
Area of larger circle = 
Area of smaller circle = 
Probability that it lands in the shaded area (smaller circle):
28.26 ÷ 379.94 = 0.07438... = 0.07 (nearest hundredth)
Answer:
-0.8 or -4/5
Step-by-step explanation:
You could do this a couple of ways. If you wanted to change your equation into slope-intercept form to make it easier for you, then you can do as follows:
4x + 5y = 10
5y = -4x + 10
y = -4/5x + 2
So your slope is -4/5.
Or you could do -A/B when your equation is in standard form. A is the term in front of the x value and B is the term in front of the y. Both strategies give you -4/5 for the slope.
Yes, again, they are correct.
