Find x if:<br> - B is between A &amp; C;<br> -AB = x + 5;<br> -BC = 2(x-3); and<br> -AB ~= BC
aliya0001 [1]

Answer:

The value of x = 11

Step-by-step explanation:

Given

  • B is between A and C.
  • AB = x+5
  • BC = 2(x - 3)
  • {\displaystyle {\overline {AB} ≅ {\displaystyle {\overline {BC}

Determining the value of x

As B is between A and C, so

{\displaystyle {\overline {AB} ≅ {\displaystyle {\overline {BC}

as

  • AB = x+5
  • BC = 2(x - 3)

so

x + 5 = 2(x-3)

x+5 = 2x-6

2x-x = 5+6

x = 11

Therefore, the value of x = 11

Please help- A bakery sells cakes for $18 each and pies for $15 each. Last weekend the bakery sold 118 total items and earned $1
Sati [7]

Answer:

64 pies sold

Step-by-step explanation:

x = number of cakes sold

y = number of pies sold

Last weekend the bakery sold 118 total items

x + y = 118

Last weekend the bakery earned $1,932.

18x + 15y = 1,932.

Get rid of one of the terms, in this case x.

x + y = 118 becomes

18x + 18y = 2124

Subtract the equations from each other

(18x - 18x) + (18y - 15y) = 2124 - 1932

3y = 192

y = 64

Subsititue y into the orginal qeuation to solve for x and check it's right.

x + 64 = 118

x = 118 - 64 = 54

18(54) + 15(64) = 1932
