Answer:
2.5 hours
Step-by-step explanation:
BB = 25 + (15x)2
SS = (20x)2
25 + 30x = 40x
10x = 25
x = 2.5
Answer:
C = pi * d = 2 * pi *r
Step-by-step explanation:
The circumference of a circle is the distance around the circle. It can be found by multiplying the diameter times pi.
C = pi * d
We can replace the diameter with twice the radius
C = pi * 2 * r = 2 * pi *r
There is no change in the y axis, so it's a vertical distance, and 8-7=1, so the distance is 1
Answer:
The correct answer is B. -3.
Step-by-step explanation:
To solve this problem, we need to plug in -3 for all of the values of x in the equation. If we do this, we get:
f(x) = 2x + 3
f(-3) = 2(-3) + 3
Now, we can just simplify the expression found on the right side of the equation using PEMDAS. First, we should perform the multiplication.
f(-3) = -6 + 3
Next, we should add our final two terms together.
f(-3) = -3
Therefore, the correct answer is -3.
Hope this helps!
