Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

$u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle$

the subtraction is simply

$u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle$

So, in your case, we have

$\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle$

Answer:the number of children tickets that were sold is 30.

the number of adult tickets that were sold is 70

Step-by-step explanation:

Let x represent the number of children tickets that were sold.

Let y represent the number of adult tickets that were sold.

The movie theater sells a total of 100 tickets. This means that

x + y = 100

The theater charges $6 per child's ticket and $10 per adult's ticket. The movie theater made a total of $880. It means that

6x + 10y = 880 - - - - - - - - - - -1

Substituting x = 100 - y into equation 2, it becomes

6(100 - y) + 10y = 880

600 - 6y + 10y = 880

- 6y + 10y = 880 - 600

4y = 280

y = 280/4 = 70

x = 100 - y = 100 - 70

x = 30

Answer:

D)$42.00

Step-by-step explanation:

18 3/4 is equal to 18.75, so 18.75x2.80 is your original cost (52.5). After doing that, since 52.5=100% you are going to divide 52.5 by 5 since 20x5=100. So 20% is 10.5. 52.5-10.5= $42.00

What is 168.023 in expanded form using fractions

bonufazy [111]

Answer:

The expanded form of 168.023 is 100 + 60 + 8 + $\frac{2}{100}$ + $\frac{3}{1000}$

Step-by-step explanation:

Expanded form:

Is a way to write numbers to see the math value of the digits.

When numbers are separated into their place values and decimal places they can also form a mathematical expression.

Ex: 5,325.27 in expanded form is 5,000 + 300 + 20 + 5 + $\frac{2}{10}$ + $\frac{7}{100}$ = 5,325.27

Let us solve the question

∵ The number is 168.023

∵ Its hundreds digit is 1

∴ Its value = 100

∵ Its tens digit is 6

∴ Its value = 60

∵ Its units digit is 8

∴ Its value = 8

∵ Its tenths digit is 0

∴ Its value = 0

∵ Its hundredths digit is 2

∴ Its value = $\frac{2}{100}$

∵ Its thousandths digit is 3

∴ Its value = $\frac{3}{1000}$

∴ The expanded form of 168.023 = 100 + 60 + 8 + $\frac{2}{100}$ + $\frac{3}{1000}$
