Yes you have a good example.
x = number of cookies
2*x = total amount spent on cookies at $2 each
2x-3 = amount you pay after the $3 discount is applied one time for the entire order
-------------
a more numeric example may be this
Lets say you bought 12 cookies, so x = 12
This means it costs 2*x = 2*12 = 24 dollars total if the discount doesnt apply
However, the 3 dollar discount is there, so the grand total is 24-3 = 21 dollars.
Answer:
16 units
Step-by-step explanation:
6.1 + 5.8 + 4.1 = 16
Answer:
sin 63° = a / 10
Step-by-step explanation:
With reference angle A
Sin A = BC / AB
Sin 63° = a / 10
Hope it will help :)
A triangles three angles always sum up to 180 degrees. We must find angle B.
We already have angle A and C, so it's quite simple.
Angle A is 28*, and angle C is 36*
We add these two together
28 + 36 = 64
Now we subtract
180 - 64 = 116
Angle B = 116*
Hope this helps you! (:
