Answer: the cost of one shirt is $28
the cost of one sweater is $23
Step-by-step explanation:
Let x represent the cost of one shirt.
Let y represent the cost of one sweater.
Lonnie purchased three sweaters and two shirts for $130. It means that
2x + 3y = 130 - - - - - - - - -1
If the sale price of a shirt was five dollars less than the sale price of a sweater, it means that
x = y - 5
Substituting x = y - 5 into equation 1, it becomes
2(y - 5) + 3y = 130
2y - 10 + 3y = 130
2y + 3y = 130 + 10
5y = 140
y = 140/5
y = 28
x = y - 5 = 28 - 5
x = 23
By definition we have the meaning of FOIL is given by:
F: First
O: Outer
I: Inner
L: Last
We have then the following product:
Applying the FOIL method we have that the products are given by:
Answer:
the answer choice showing the FOIL method products is:
B. (X) (4x) + (2) (x) + (- 3) (4x) + (- 3) (2)
If over you mean division then it would be 2556 divided by 5000 and that would equal 0.5112 and if you meant it to be addition because sum means the answer of an addition problem then it would be 7556 because of 2556 plus 5000, but i dont know if that is what you meant by your question. if you explain the lesson to me that you are learning, then i might be of more help to you in solving your problem.
The answer is.
And if you need it on decimal form, it would be,
