Please help me with this
pantera1 [17]

Answer:

  • 8 3/4
  • 2, 3
  • 4 1/2, 11 1/4
  • 9 3/4, 16 1/4
  • Y/B = 2/3

Step-by-step explanation:

<h3>a)</h3>

The first line is simply the sum of the two given numbers.

  3 1/2 +5 1/4 = (3+5) +(2/4+1/4) = 8 3/4

__

To find values on the remaining lines, it is convenient to find the ratios of the numbers involved. The ratio of yellow to blue is ...

  Y/B = (3 1/2)/(5 1/4) = (7/2)/(21/4) = (7/2)(4/21) = 2/3

Then ...

  Y : B : total = 2 : 3 : 5

This tells you the numbers on the second line are ...

  Y = 2; B = 3

__

The value for B on the third line is the basic ratio number multiplied by (6 3/4)/3 = 2 1/4. Then the other two numbers are ...

  Y = 2(2 1/4) = 4 1/2

  total = 5(2 1/4) = 11 1/4

__

The value for Y on the fourth line is the basic ratio number multiplied by (6 1/2)/2 = 3 1/4. Then the other two numbers are ...

  B = 3(3 1/4) = 9 3/4

  total = 5(3 1/4) = 16 1/4

_____

<h3>b)</h3>

The equation is the one we used to find the values on the second line:

  Y/B = 2/3

Preform the subtraction: (5x^2 -3xy +10y^2) - (12x^2 +11xz- 7z^2)
Rzqust [24]

we are given

(5x^2 -3xy +10y^2) - (12x^2+11xz-7z^2)

we have to subtract

step-1:  Distribute negative sign

=5x^2 -3xy +10y^2-12x^2-11xz+7z^2

step-2:Combine like terms

=5x^2 -12x^2-3xy -11xz+10y^2+7z^2

=-7x^2-3xy -11xz+10y^2+7z^2

we get

=-7x^2-3xy -11xz+10y^2+7z^2............Answer
