Answer:
x = 710
Step-by-step explanation:
1. Divide both sides by 2 to get x by itself
1420 = 2x
↓
1420 ÷ 2 = 2x ÷ 2
↓
710 = x
2. Switch sides
710 = x
↓
x = 710
I know it is not one of your options but that is the answer to 1420 = 2x
Answer:
b
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ( where r is the radius )
Here r = 3, thus
V = π × 3³
= π × 27 = 4π × 9 = 36π in³ → b
Answer:
8 carnations and 12 zinnias
Step-by-step explanation:
Answer:
w=-1.16u
Step-by-step explanation:
first you want to put the W's on one side and the U's on the other. we can do this by subtracting 4u from the left side and the right side making the equations 8w=-7u+2w.
next we want to subtract 2w from both sides making the equation 6w=-7u then we divide by 6 to get w=-1.16u
You move the decimal point forward until it reaches the one so it looks like this:
1.4 x 10⁵
the exponent, 5, just tells you how many spaces the decimal point moved.
