Answer:
soln
let x=n in order to differentiate btn x and multiplication sign.
first of all we apply cross multiplication.
14/4×n/2
(4×n)=(14×2)
open blacket
4n=28
we divide by 4 both side
n=7
therefore
x=7

$18.20/0.65=28 minutes
Step-by-step explanation:
$18.20 was the cost of the rental divide it by the cost per minute and that will give you the total number of minutes used which is 28.
X²+4=29
Collect like terms
X²=29-4
X²=25
Take the square root of both sides to find the value of X
√X² = √25
X = 5
X - 4 =5 - 4=1
Answer:
y = 12x
Step-by-step explanation:
Given that:
y = cost of making a special order cupcake
A dozen of special order cupcakes = 12 pieces
Let the cost of extra ingredient for making a special order cupcake = x
Hence the cost y of making a dozen of such special order will be :
y = extra cost per order * number of orders
y = 12x
