35 + 30x = 55 + 20x
-35 -35
30x = 20 + 20x
-20x -20x
10x = 20
/10 /10
x = 2

=
, substitute values
=
=
( cross- multiply )
2x = 12 ( divide both sides by 2 )
x = 6
Answer:
a) 40 inches
b) No it will not fit inside
Step-by-step explanation:
Angharad is buying a new 50-inch screen TV (remember that TV screens are measured along the diagonal )
a) If it is 30 inches tall, how wide is the screen ?
Diagonal ² = Width² + Height²
Diagonal = 50 inches
Height = 30 inches
50² = Width² + 30²
Width² = 50² - 30²
Width = √50² - 30²
Width = √(1600)
Width = 40 inches
b) Her TV cabinet is 30 inches wide .will the TV fit inside it ?
No it will not fit inside
This is because, the width of the TV is the above calculation is 40 inches. This is wider than the width of the TV cabinet, hence, it won't fit inside
