The total cost, in pounds, for X jumpers at £15 each and Y shirts at £12 each can be written as the mathematical expression: 15X + 12Y, where X and Y are the quantities of jumpers and shirts respectively.
To write an expression for the total cost of X jumpers at £15 each and Y shirts at £12 each in pounds, you need to multiply the cost per item by the quantity of each items and then add these two products together.
So, the total cost can be given as:
where
In this expression, '15X' stands for the total cost of the jumpers and '12Y' stands for the total cost of the shirts.

4/11 (2/2) = 8/22
4/11 (3/3) = 12/33
4/11 (4/4) = 16/44
To solve for 'f' in the algebraic equation 's=3f-24', add 24 to 's' and then divide the result by 3.
To solve the algebraic equation 's=3f-24' for 'f', you would first decide to isolate 'f'. To do this, start by getting rid of the '-24' on the right side of the equation by adding 24 to both sides. This would simplify the equation to 's+24=3f'. Next, divide both sides of the equation by 3. This step will result in a final solution of 'f=(s+24)/3'. So, to solve for 'f' in the provided equation, simply add 24 to the original 's' value and then divide the result by 3.

b x + (x + 8) =72
c x(x + 8) = 72
d x(x - 8) = 72
Answer:
let x is the smaller number
bigger number is x + 8
The sum of two numbers is 72
so
x + (x+8) = 72
answer
x + (x + 8) = 72
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Two numbers add up to 72
let's assume they r x and y
ome number is 8 more than the other
so it will be xand x+8
Therefore x+x+8=72
(2) (x^2 + 6)(x^2 + 6) (4) (x^2 + 6)(x^2 - 6)
The expression is equivalent to x^4 - 12x^2 + 36 is (x^2 - 6)(x^2 - 6) correct.
We have given that
x^4 - 12x^2 + 36
We have to determine
Which expression is equivalent to x^4 - 12x^2 + 36.
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).
(x^2 plus or minus 6)(x^2 plus or minus 6)
an easy way to do this is to only look at plus or minus 6
x^4 - 12x^2 + 36 (-12 and 36)
6 x 6 = 36
6 + 6 ≠ -12
(x^2 + 6)(x^2 + 6) is incorrect
6 x -6 ≠ 36
6 + -6 ≠ -12
(x^2 - 6)(x^2 + 6) is incorrect
-6 x -6 = 36
-6 + -6 = -12
Therefore the option (x^2 - 6)(x^2 - 6) is correct
The expression is equivalent to x^4 - 12x^2 + 36 is (x^2 - 6)(x^2 - 6) correct.
