Given:
The ratio of the cost of a shirt to the cost of a jacket is 2:5.
The jacket cost $240 more than the shirt.
To find:
The cost of the shirt and the cost of the jacket.
Solution:
Let x be the cost of the shirt.
The jacket cost $240 more than the shirt. So, the cost of Jacket is (x+240).
The ratio of the cost of a shirt to the cost of a jacket is 2:5. So,
Subtract 2x from both sides.
Divide both sides by 3.
So, the cost of shirt is $160.
Now, the cost of jacket is:
Therefore, the cost of shirt is $160 and the cost of jacket is $400.
Answer:
$12 + $25 = $37
9.25% of 37 is 3.4225 (rounds to 3.42)
$37 + $3.42 = $40.42
Sales tax: $3.42
Total amount spent: $40.42
Answer:
n + 5
Step-by-step explanation:
if last year melly was N year old, she is now n+1 years old.
So, in four years, she will be
(n + 1) + 4 years old
meaning that she will be n + 5 years old.
hope this helps!! :)
Changing the coefficient of x to 6 changes the meaning of the expression as 5 is added to 6 times x
Solution:
Given that number 2 in the expression 5 + 2x is called the coefficient of x
We are asked to find what happens when changing the coefficient to 6 changes the meaning of the expression
In the expression,
5 + 2x
This means 5 is added to 2 times x or 5 is added to twice of x
Number 2 is called the coefficient of x
When we change this coefficient to 6, the expression becomes,
5 + 6x
So now the meaning of expression becomes,
5 is added to 6 times x
So changing the coefficient of x changes the meaning of the expression
