Answer : -3.3b + 3.5x - 84.82
(-14.2b - 97.35) + (10.9b + 12.53 + 3.5x)
= (-14.2b + 10.9b) + (3.5x) + (-97.35+12.53) ||| COMBINE LIKE TERMS
= -3.3b + 3.5x - 84.82
1) 100% - 30.2%=69.8%
The cost of the bracelet is 69.8% of the initial price.
2) $28170 ----- 100%
$ x ------ 69.8 %
x=(28170*69.8)/100 = 19662.66
Answer is $19662.66.
Answer:she spent 10 hours working in her aunt's store last week.
Step-by-step explanation:
Let x represent the number of hours that Lee spent working at the movie theater.
Let y represent the number of hours that Lee spent working at her aunt's store.
Lee worked a total of 30 hours at the movie theater and her aunt's store. This means that
x + y = 30
Her combined pay from the jobs was $240. She earned $9 per hour working at the movie theater and $6 per hour working in her aunt's store. This means that
9x + 6y = 240 - - - - - - - - - -1
Substituting x = 30 - y into equation 1, it becomes
9(30 - y) + 6y = 240
270 - 9y + 6y = 240
- 9y + 6y = 240 - 270
- 3y = - 30
y = - 30/ - 3 = 10 hours
68 is composite it has more factors than 1 and itself
Answer:
Step-by-step explanation:
6(5+x) = 30 + 6x
1. Distribute the 6 to both the 5 and the x.
7x5x3 = 105
1. Just multiply them together.
28 - 3(2+4)/9 = 26
1. PEMDAS
2. Add inside the parenthesis: 28 - 3 x 6 / 9
3. Multiply: 28 - 18 / 9
4. Divide: 28 - 2
5. Subtract: 26
