Answer:
n(B') = 15
Step-by-step explanation:
Assumunin U is the universal set.
B = { 7,11,17,19}
B' = natural numbers different form 7,11,17 and 19 = {1,2,3,4,5,6,8,9,10,12,13,14,15,16,18}
Answer:
<u>Step-by-step explanation:</u>
Move all of the x's to one side and everything else on the other.
ax = bx + c
ax - bx = c <em>subtracted bx from both sides</em>
x(a - b) = c <em>factored out the like term of "x" on left side</em>
<em>divided both sides by (a- b)</em>
2x = x + 7 → a = 2, b = 1, c = 7
x = 7
<u>Check:</u>
2x = x + 7
<u>-x </u> <u>-x </u>
x = 7
Answer:
$102.33
Step-by-step explanation:
586= 4t + 2(t+7)
586= 4t +2t +14= 6t +14
572= 6t
95.33=t
adult ticket = t +7
The service plans are illustrations of linear equations
It will take 125 minutes for the plans to have the same cost
<h3>How to determine the number of minutes</h3>
From the question, we have the following parameters
<u>Service plan 1</u>
- Monthly fee = $16
- Charges = $0.15 per minute
<u>Service plan 2</u>
- Monthly fee = $21
- Charges = $0.11 per minute
So, the linear equations for both plans are:
When the plans cost the same, we have:
Collect like terms
This gives
Solve for x
Hence, it will take 125 minutes for the plans to have the same cost
