Answer:
Step-by-step explanation:
25 × 4.5= 112.5 and that is you answer
<span>17<=3-2x<=21
subtract 3
14<=-2x<=18
divide by 2
7<=-x<=9
now mutiply whole inequality by -1, this will reveres the inequality
-7>=x>=-9
or -9<=x<=-7
so there are mistakes in the line
the corrected lines are
17 less than or equal to 3 - 2x and 3 - 2x less than or equal to 21 (line one)
14 less than or equal to -2x and -2x less than or equal to 18 (line two)
-7 greater than or equal to x and x greater than or equal to -9 (line three)</span>
Here you will use the product rule and power rule of logarithms, if the bases are the same with operation of addition they can be presented as a product of logs and the power rule, you can place the exponent of the log in front of the log and vise versa.
Power rule:
3log3 q + 6 log 3 v
log3 q^3 + log3 v^6
Product rule:
log3 q^3 + log3 v^6
log3 (q^3v^6)
It is shown as a sum of each digit multiplied by its matching place value<span> (units, tens, hundreds, etc.) For example: 4,265 = </span>4<span> x 1,000 + 2 x 100 + 6 x 10 + 5 x 1.</span>
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
