Given:

James bought 22 candy bars for $137.

If the king size candy bars cost $8 and a regular size candy bar cost $5.

To find:

The system of equation and solution of it.

Solution:

Let x be the number of king size candy and y be the number of regular size candy.

Quantity: x+y=22           ...(i)

Cost : 8x+5y=137        ...(ii)

Multiply the equation (i) by 5.

5x+5y=110           ...(iii)

Subtract (iii) from (ii).

8x+5y-5x-5y=137-110

3x=27

x=9

Put x=9 in (i).

9+y=22

y=22-9

y=13

Therefore, number of king size candy is 9 and number of regular size candy  is 13.

Y = 11.5x + 22
y = -13x + 218

when will their balance be the same.....ur basically just subbing in 1 y for the other and u get :
11.5x + 22 = -13x + 218....now we solve for x
11.5x + 13x = 218 - 22
24.5x = 196
x = 196 / 24.5
x = 8 <== they will be the same at 8 weeks

11.5(8) + 22 = 114
-13(8) + 218 = 114
and they will both have $ 114 at 8 weeks <===

Answer:

Step-by-step explanation:

Fist let's have a look :

  • (AB) is parallel  with (CD) and there is a line crossing them both.

Now the first question : What is the size x ?

  • We notice that x and 53° are vertically opposite so they are corresponding angles
  • so the size of x is 53°

The second question : what is the size of y ?

  • We notice that y and 53° are alternate angles
  • so they are corresponding angles with same size
  • y=53°

The trick is to khow the situation where we have  corresponding angles
