If there is a 506,211 pound whale on a scale and you add another whale of 424,809 pounds on the scale how much would they both weigh?
Answer:
x ≤ 17
Step-by-step explanation:
This is the same as solving an equation, except instead of and equal sign it's an arrow.
We have to evaluate everything in the parenthesis first.
3x - 2 (x + 1) ≤ 15
3x - 2x - 2 ≤ 15
Next, we combine like terms - x's
3x - 2x - 2 ≤ 15
x - 2 ≤ 15
Combine like terms - constants (add 2 to both sides)
x - 2 ≤ 15
<u>x ≤ 17</u>
Answer:
c.
314 sq. cm
Step-by-step explanation:
Surface area of sphere:
The surface area of an sphere with radius r is given by:

Find the surface area of a sphere with a diameter 10 cm.
Radius is half the diameter, so 
The surface area is:

314 square centimeters, and option c is the answer.
Step-by-step explanation:
f(x) = 2x - 1
f(10) = 2(10) - 1
= 20 - 1 = 19
I think the answer to that is 58
