angle 2 is also 65º because they are corresponding angles. Using the vertical angles theorem, you can also say that angles 3 and 7 are 65º. so the answer to your question would be angle 3
The price of a senior citizen ticket is $8 and the price of a student ticket is$ 10
Step-by-step explanation:
Let the cost of one seniors citizen ticket be x and student be y
First day:
10 seniors citizen tickets and 11 student for a total of $190.
10x + 11y = 190-----------------------------(1)
Second day:
$160 on the second day by selling 5 senior citizen tickets and 12 student tickets.
5x + 12y = 160---------------------------------(2)
Multiply eq(2) by 2
10x + 24y = 320----------------------------(3)
Subtract eq(1) from (3)
10x + 24y = 320
10x + 11y = 190
-----------------------------
0x + 13 y = 130
---------------------------
13y = 130

y = 10-------------------------------(4)
Substituting (4) in (2)
5x + 12(10) = 160
5x + 120 = 160
5x = 160-120
5x = 40

x = 8
Answer:
4u^2 + 16u + 15
Step-by-step explanation:
Multiply each of the terms in the first binomial by each of the terms of the second binomial (4 multiplications in all).
(2u + 3)(2u + 5) = (2u)(2u + 5) + 3(2u + 5)
= (2u)(2u) + (2u)(5) + 3(2u) + 3(5)
= 4u^2 + 10u + 6u + 15
= 4u^2 + 16u + 15
the awnser to your question is 48 because you are just subtracting
