Distribute
a(b+c)=ab+ac so
-3(x-5)=-3x+15
-8(y+2)+-8y-16
-3(6-4b)=-18+12b
add them together
-3x+15-8y-16-18+12b
associative property
15-16-18-3x-8y+12b
add
-19-3x-8y+12b is the answer which is D

Expand the expressions:

-3x+15-8y-16-18+12b

Combine like terms:

-3x-8y+12b-19

Now, we have fully simplified this expression.  D is the correct answer.

Anna is selling tickets to the school's gymnastics competition. On the first day, she sells 5 adult tickets and 6 child tickets
Lorico [155]

The cost of each adult ticket is $11.43

The cost of each child ticket is $0.14

<u>Step-by-step explanation:</u>

Given,

  • The cost of each adult ticket = x
  • The cost of each child ticket = y

On the first day,

Anna sells 5 adult tickets and 6 child tickets for a total of $58.00.

⇒ 5x + 6y = 58  ----------(1)

On the second day,

she sells 8 adult tickets and 11 child tickets for a total of $97.00.

⇒ 8x + 11y = 97  ----------(2)

<u>Solving the equations for x and y values :</u>

Multiply eq (1) by 8,

Mu;tiply eq (2) by 5 and subtract it from eq (1),

  40x + 48y = 484

- (<u>40x + 55y = 485</u>)

  <u>        - 7y = - 1     </u>

⇒ y = 1/7

⇒ y = 0.14

The cost of each child ticket is $0.14

Substitute y = 0.14 in eq (1),

⇒ 5x + 6(0.14) = 58

⇒ 5x + 0.84 = 58

⇒ 5x = 58 - 0.84

⇒ 5x = 57.16

⇒ x = 57.16 / 5

⇒ x = 11.43

The cost of each adult ticket is $11.43

Peter wants to fence the park in front of his home on three sides which measure 152m 40cm, 205m 10cm, 310m 39cm. What is the tot
Tpy6a [65]

One centimenter is 0.01 meters. So, you can write the measures as

152.40\text{m},\quad 205.10\text{m},\quad 310.39\text{m}

Once this rewriting is done, getting the total length T is quite trivial, since all measurements are in the same unit, and we can simply sum everything:

T = 152.40+205.10+310.39 = 667.89
