Answer:
1,5,6
Step-by-step explanation:
Answer: a = c^(1/2) which is the first answer choice of the list
Work Shown:
a = b^(2/3) ... given equation
a = (c^(3/4))^(2/3) ... replace b with c^(3/4)
a = c^((3/4)*(2/3)) .... multiply exponents
a = c^(1/2) .... Simplify; note the 3's cancel, also 2/4 turns into 1/2
Let, Price of a shirt = x
Price of a Jeans = y
Equations would be: 4x + 3y = 150
x + 2y = 70
x = 70-2y
Substitute it into first equation,
4(70-2y) + 3y = 150
280 - 8y + 3y = 150
-5y = -130
y = 130/5
y = 26
Substitute it into 2nd equation,
x + 2(26) = 70
x = 70-52
x = 18
So, Cost of a Shirt = $18 & Cost of a Jeans = $26
Hope this helps!
