To find the area of a rectangle, we multiply the Base by the Height. In this case the: Base = AB and Height = BC
So to get the area, we multiply AB by BC. (and we know that <em>BC = 5x+5/x+3</em> <em>and BC = [3x+9/2x-4)</em>
So we would do:
x
Note: When multiplying fractions together, we multiply the numerator by the numerator, and the denominator by the denominator.
For example x =
Answer: x =
= [<em>Note: </em><em>we are able to factorise some brackets to make the sum easier. For example we can factor out the 5 in (5x+5) to get: 5(x+1) ]</em>
Now lets simplify by multiplying the 5 and 3 together in the numerator:
=
If you notice, there is a (x+3) in numerator and the denominator. This means that we can cancel out the (x+3), to get the most simplified expression for the area:
=

Answer:
25/416
Step-by-step explanation:
Maybe you want to know the value of ...
(1 1/4)/(20 4/5) = (5/4)/(104/5) = (5/4)×(5/104) = (5×5)/(4×104) = 25/416
Sarah bought 3 bracelets and 2 pairs of sunglasses.
Step-by-step explanation:
Total items bought = 5 items
Total spent = $24
Cost of one bracelet = $5
Cost of pair of sunglasses = $4.50
Let,
x be the number of bracelet bought.
y be the number of sunglasses bought.
According to given statement;
x+y=5 Eqn 1
5x+4.50y=24 Eqn 2
Multiplying Eqn 1 by 5
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 0.50
Putting in Eqn 1
Sarah bought 3 bracelets and 2 pairs of sunglasses.
