so, start floor = x
x + 7 - 9 - 4 + 8 - 2 = 14
x = 14
the elevator started on the 14th floor.
to verify: 14 + 7 = 21 - 9 = 12 - 4 = 8 + 8 = 16 - 2 = 14
Answer: ~5
Step-by-step explanation:
It's been awhile for me but I think you do sin=opp/hyp
sin(45)=3sqrt(2)/x
x = 3sqrt(2)/sin(45) = (approx) 5
Answer:
w + 8
Step-by-step explanation:
Answer:
4x <= 20
x <= 5
A single cupcake can cost at most $5.
Step-by-step explanation:
Let the price of a single cupcake be x.
We know that there are 4 cupcakes in a box, so 4x is equal to the price of 4 cupcakes and hence the price of a box.
The question tells us that a box costs at most $20, so we can write this as an inequality:
4x <= 20
Divide both sides by 4 to isolate and solve for x:
x <= 5
x is less than or equal to 5, which can be interpreted as a cupcake costing at most $5.
Nothing is here I need a question sorry
