Step-by-step explanation: all you do is subtract 12 from each side and you will get -5
Ok I’ll break this down so it’s easier to understand:
So you start of with $80
The first step is to find 20% off
An easy way to find 20% is to divide it by 5.
80/5= 16
And since it’s 20% OFF we subtract 16 from 80
80-16= 64
Next we need to do the coupon
It is $5 off so
64-5= 59
And finally the rebate which is $2
59-2= 57
Answer:
57

Answer:

Step-by-step explanation:
Let
- D be the event that the card drawn is a black card
- F be the event that the card drawn is a 10 card
- F' be the event that the card drawn is not a 10 card
The probability

Note that

So,

A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
