Answer:

Step-by-step explanation:

1. 2a + 3a + 3 = 8

5a + 3 = 8

5a = 5

a = 1

2. 3a - 2a - 4 = 0

    a - 4 = 0

     a = 4

3. 4 + 3a + 6 = 16

   3a + 10 = 16

    3a = 6

     a = 2

4. 12a - 6a + 6 = 24

     6a + 6 = 24

     6a = 18

      a = 3

*Hana purchased 2 pairs of pants for $26.59 each and a coat for $49. She used a coupon that saved her $10. The sales tax for the
Verizon [17]

Answer:

$100.02

Step-by-step explanation:

*Sales tax is always applied after the discount/coupon

1. Find how much Hana had spent on pants. Since she had bought 2 pairs of pants, and they are $26.59 <u>each,</u> we would have to multiply 26.59 by 2. So,

26.59 times 2 is 53.18.

Hana spent $53.18 on pants

2. Find how much Hana had spent on a coat. Since she had bought 1 coat, and they are $49.00 <u>each,</u> we would have to multiply 49.00 by 1. So,

49.00 times 1 is 49.

Hanna spent $49 on coats

3. Find how much Hana spent on clothes. Since she spent $53.18 on pants and $49 on coats, we would have to add 53.18 and 49. So,

53.18+49=102.18

Hanna spent $102.18 on clothes

4. Find how much Hana "spent" after using the coupon. Since the problem says the coupon helps Hana <u>save</u> $10, we need to subtract 10 from 102.18(the total amount of money Hana spent on clothes before using the coupon). So,

102.18-10=92.18

Hanna "spent" $92.18 on clothes after using the coupon

5. Find how much was the total purchase. Sales Tax is the amount of money that needs to be <u>added</u> to the price. Since the price is $92.18 and the sales tax is $7.84, we need to add 7.84 to 92.18. So,

7.84+92.18=100.02

The total purchase is $100.02

One number is 18 more than another number. The sum of the numbers is 36. find the numbers
tatuchka [14]

We can use a system of equations in order to solve for both of the numbers. Let's start off by assigning variables to each number. The bigger number can be 'x', and the smaller number can be 'y'.

We can make two equations from the given:

x = 18 + y

("One number is 18 more than another number")

x + y = 36

("The sum of the numbers is 36")

If you look at the first equation, the variable 'x' already has a value (18 + y). We can input its value into the second equation in order to solve for y:

x + y = 36

(18 + y) + y = 36

18 + 2y = 36

2y = 18

y = 9

Input the value of 'y' into the first equation:

x = 18 + y

x = 18 + 9

x = 27

<u>One number is 27 and the other number number is 9.</u>

<u></u>

Let me know if you'd like me to explain anything I did here.

Can anyone help me with this question?
lesya692 [45]

Answer:

The Answer is A. (x, y) → (x, -y)

Step-by-step explanation:

Reflections

R x-axis (x, y) → (x, -y)

R y-axis (x, y) → (-x, y)

R y=x (x, y) → (y, x)

R y = -x (x, y) → (-y, -x)
