Answer: how many square feet are there? multiple each square foot by 2
Step-by-step explanation:
Answer:
3/2
Step-by-step explanation:
Step 1
Multiply the denominator by the whole number
2 × 1 = 2
Step 2
Add the answer from Step 1 to the numerator
2 + 1 = 3
Step 3
Write answer from Step 2 over the denominator
3/2
Answers: Choice A and Choice E
0.82B and B-0.18B
========================================================
Explanation:
B is the cost of the game (some unknown amount). Subtract off 0.18B to indicate a 18% reduction in the price. That's how we get choice E.
Simplifying choice E leads us to choice A. Notice that 1 - 0.18 = 0.82; which represents 100% - 18% = 82%. After the discount, Bo is paying 82% of the original price.
Side note: Choice B indicates an 18% increase. Choices C and D don't represent percentage decreases (rather they're decreasing by a fixed amount regardless of what B is).
Answer: x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2
Step-by-step explanation:
2x^2 = 4 + 6x
divide both sides by 2
x^2 = 2 + 3x
move expression to the left
x^2 - 2 - 3x = 0
reorder the terms
x^2 - 3x - 2 = 0
use the quadratic formula
x = - (-3) +- sqrt (-3)^2 - 4 x (-2) / 2 x 1
calculate
x = 3 +- sqrt 17 / 2
answer
x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2
