This is the answer
Answer:
$26.02
Step-by-step explanation:
Let the price of a skirt be A and that of coat be B
Iilly bought 6 skirts and 5 coats for a total of $452.62
That’s
6A + 5B = 452.62
Also, Lilly’s sister bought 3 skirts and 5 coats for $289.36
That’s
3A + 5B = 289.36
We now have two equations
1 . 6A + 5B = 452.62
2. 3A + 5B = 289.36
Subtract equation two from equation one
We have
3A = 163.26
Divide both sides by 3
3A/3 = 163.26/3
A = 54.42
A = $54.42
Now substitute 54.42 for A in either equations to get B the price of a coat
Using equation one, we have
6A + 5B = 452.62
6 x 54.42 + 5B = 456.62
326.52 + 5B = 456.62
Subtract 326.52 from both sides
326.52 - 326.52 + 5B = 456.62 - 326.52
5B = 130.1
Divide both sides by 5
5B/5 = 130.1/5
B = 26.02
= $26.02
A coat cost $26.02
It would be -50 because the rule is subtract by 2 then 4 then 6 then 8 and etc.
WARNING THIS IS THE WRONG ANSWER in case any of you look at this
Answer:
x = -1
Step-by-step explanation:
2x + 3(2) = 4
2x + 6 = 4 Multiply 2 and 3 to get 6.
2x = -2 Subtract 6 from both sides to isolate 2x.
x = -1 Divide both sides by 2 to find x.
