Answers: Weight - 7.62 pounds, Cost - $2.50
When we convert 3,456 grams into pounds, we get 7.62 pounds (rounded to the nearest hundredth). We can subtract the first pound off since we know that will cost $0.75 (7.62 - 1 = 6.62 pounds). Now we must round 6.62 up to 7 pounds and multiply that by the price for every pound or part of a pound (7 x 0.25 = $1.75). Now you combine both the cost of the initial pound and the cost of every pound or part of a pound over the first to get your final cost. ($0.75 + $1.75 = $2.50)
Answer:
42
Step-by-step explanation:
a = 2, b = 5, and c = 1
- a*(4b + c²) = ⇒ plug in values
- 2*(4*5 + 1²) = ⇒ solving exponents
- 2*(20 + 1) = ⇒ parenthesis
- 2*21 = ⇒ multiplication
- 42 ⇒ answer
Answer:
(x-7)/(x+2)
Step-by-step explanation:
(x-7)(x+7)/(x+7)(x+2)
(x-7)/(x+2)
At least means it can be larger than or equal to.
X >= 15
No more than means less than or equal to:
X <= $7
