Answer:
168 unlimited-ride passes.
Step-by-step explanation:
50x+20y=10680
x+y=282
Multiply.
20(x+y=282)
20x+20y=5640
Subtract.
50x-20x+20y-20y=10680-5640.
30x=5040
x=168
Hope this helps plz hit the crown :D
Answer:
Less; $25.90 less than at the beginning of the week
Step-by-step explanation:
162-(63.50+23.25+26.45)=162-113.20=48.80
48.80+87.30=136.10; 162>136.10
162-136.10=Δ$25.90
$25.90 less

Step-by-step explanation:
Alcohol sanitizer is good until the alcohol evaporates, about 30 seconds. It is a cleaner, that kills the pathogens already on your hands. If you recontaminate your hands, you need to reapply.
The Factorization of 121b⁴ − 49 is (11b^2 + 7)(11b^2 - 7).
The equation 121b⁴ − 49
To find the Factorization of 121b⁴ − 49.
<h3>
What is the factor of a^2-b^2?</h3>
The factor of a^2-b^2 is (a+b)(a-b)
We have write the given equation in the form of a^2-b^2

Therefore the factor of the 121b^4 − 49 is (11b^2 + 7)(11b^2 - 7).
