We know some facts:
- x for the original price.
- The store has a coupon for $10 off and a discount of 20%
- C for the price after the coupon is applied.
So from the statement 2, you can realize there are two types of discounts:
- The discount offered by the coupon
- The discount offered by 20%
Since we need to write a function just for the coupon, then we don't include the discount offered as percentage, then we subtract the coupon from the original price:
Answer:
12x+8-30x+5=2x-16-42x+24
-18x+13=-40x+8
22x=-5
x=-5/22
hopefully i did it with out mistakes
Answer:
x = 4
Step-by-step explanation:
note the exact value of tan60° = 
Since the triangle is right use the tangent ratio to find x
tan60° = 
= 
multiply both sides by x
x × = 4
divide both sides by
x = 
= 4 × 
= 4
Answer:
r = 13, 3
Step-by-step explanation:
| r - 8| = 5
All solutions for r by breaking the absolute value into the positive and negative components
r = 13, 3
What the two or more numbers or amounts? Something needs to be compared
