Answer:
So, 89 Adult tickets were sold.
Step-by-step explanation:
So, we first name our variables, say, a for number of adult tickets, and c for child tickets.
Then we write our system of equations, first the total $ sale:
5.2c + 8.3a = 1087.10
Then we write the 2nd equation, the total number of tickets:
c + a = 156
Now, we can solve the system:
We do have different methods, let's to by subsitution.
make some change to the 2nd equation, to make c the subject: c = 156 - a
Now we plug that into the 1st equation:
5.2(156 - a) + 8.3a = 1087.10
811.2 - 5.2a + 8.3a = 1087.10
811.2 + 3.1a = 1087.10
3.1a = 275.9
a = 89
Answer:
80 degrees
Step-by-step explanation:
100 + angle A = 180
180-100= 80
So, the measure of angle A is 80 degrees
<span>When you write a number in expanded form you show how much each digit values, according its place in the number. For example, in the number 123, 3 values 3, 2 values 2*10 = 20 and 1 values 1*100 = 100, so the expanded form is 100 + 20 + 3. Using this with 84,000, you have the 8 is in the place of ten thousands, 4 is in the place of one thousand, 0 is in the place of hundreeds, 0 is in the place of tens, and 0 is in the place of units. So, the expanded form is: 80,000 + 4000. </span>
Answer:
By examining the line plot, we find the number with the maximum number of crosses or occurrences. This gives the mode of the data set. We find the smallest and the largest number from the data set and find their difference and this difference is the range of the given data set.
