Answer:
The answer to the expression is 8
Since the number after the decimal is greater than 5. Therefore you have to round 7 by adding 1 so
the answer is 638.
Answer:
<h3>2.2</h3>
Step-by-step explanation:
- (6y-22) = (y-11)
- 6y-22 = y-11
- 6y-y = -11+22
- 5y = 11
- y = 11/5
- y = 2⅕ or 2.2
Answer:
adult tickets are $8 and student tickets are $14
Step-by-step explanation:
to find the price of adult and student tickets, first look at all the given values:
a = adult tickets
s = student tickets
so: 4a + 5s = 102
and : 7a + 5s = 126
since in both equations the number of student tickets are the same, we have to find the difference of value to determine how much adult tickets are:
126-102 = 24
there are 3 more adult tickets in the equation with a total of 126, therefore:
24 / 3 = 8
that means each adult ticket is work 8 dollars.
now substitute this value:
4(8) + 5s = 102
32 + 5s = 102
you can solve this by concluding that 102- 32 is 70
that means 5(s) has to equal 70
so 70 / 5 = s
70/5 = 14
so the value of s = 14 and the value of a = 8
