Answer: The system of equations represents the constraints in this situation are:
s + h = 40
$18s + $14h = $700
The above equations are known as simultaneous equations. 40 scarves and hats were sold, this can be represented with this equation:
number of hats sold + number of scarves sold = 40
s + h = 40
The total amount made from the sales is the sum of the total amount made from the sale of the hats and the total amount made from the sale of the scarves. This can be represented with this equation:
($18 x s) + ($14 x h) = $700
Step-by-step explanation:
Let a be the first term and d be the common difference
t5 = 3 = a + 4d
t7 = 7 = a + 6d
a + 6d - a - 4d = 7 - 3
2d = 4
d = 2
Sub d = 2,
3 = a + 4(2)
a = -5
t2 = a + d
t2 = -5 + 2
t2 = -3
Answer:
Remember that when a variable is times with a number, you will <u>divide</u> it by that number which is times with variable on both sides.
when a variable is divided by the number, you will <u>multiply</u> it by that number on the both sides.
I hope you understand my explanation. Thank you !!
Take the common denominator and divide by 3
