Answer: $(d-3c)
Step-by-step explanation:
Total amount Tina had = $d
Cost of cupcakes = $c
Number of cupcakes purchased = 3
Therefore,
Total cost of cupcakes = cost per cupcake × number of cupcakes
Total cost of cupcakes = $c × 3 = $3c
Amount left after cupcake purchase:
Total amount Tina had - total cost of cupcakes :
$d - $3c
Answer:
x =12.82
Step-by-step explanation:
1/2(x-6.5) = 3.16
Multiply each side by 2
1/2(x-6.5) *2 = 3.16 *2
(x-6.5) = 6.32
Add 6.5 to each side
(x-6.5+6.5) = 6.32+ 6.5
x =12.82
Answer:
Nico, Raj and Sandra are correct
Step-by-step explanation:
we have

<em>Method 1</em>
Solve for x
That means ----> isolate the variable x
we have

Multiply by 5/2 both sides


subtract 6 both sides


<em>Method 2</em>
Solve for x
That means ----> isolate the variable x
we have

Multiply by 1/2 both sides


Multiply by 5 both sides


subtract 6 both sides


<em>Method 3</em>
Solve for x
That means ----> isolate the variable x
we have

Apply distributive property left side


subtract 2 both sides


Multiply by 5/2 both sides


therefore
Nico, Raj and Sandra are correct
Uh idek but i think the relationship is that x is plus 1 every time and y is plus 4 every time
Here's how to convert 0.39 to a fraction...
There is not much that can be done to figure out how to write 0.39 as a fraction, except to literally use what the decimal portion of your number, the .39, means.
Since there are 2 digits in 39, the very last digit is the "100th" decimal place.
So we can just say that .39 is the same as 39/100.
So your final answer is: 0.39 can be written as the fraction 39/100 (ALREADY SIMPLIFIED)
