Can of baked beans = x
packet of brown sugar = y
packet of biscuit = z
5x + 4y + 2z = 150 - 26 ⇒ 5x + 4y + 2z = 124 is the total cost of all items.
can of baked beans = x = 1/2 of z
packet of sugar = y = z - 3
5(z/2) + 4(z-3) + 2z = 124
5z/2 + 4z - 12 + 2z = 124
5z/2 + 6z = 124 + 12
2(5z/2 + 6z) = 2(136)
5z + 12z = 272
17z = 272
z = 16 cost of a packet of biscuit.
x = 1/2 of z = 16/2 = 8 cost of a can of baked beans
y = z - 3 = 16 - 3 = 13 cost of a packet of sugar
5x + 4y + 2z = 124
5(8) + 4(13) + 2(16) = 124
40 + 52 + 32 = 124
124 = 124
8(8) + 1(13) + 6(16) = 64 + 13 + 96 = 173 total cost on question 3.
Answer:
The final cost for the backpack would be $38.04.
Step-by-step explanation:
Q1: (x-2) * (2x+1)
Q2: (x-3) * (3x +1)
Q3: (4x -8) * ( 2x+3)
Q4: (7/12) +/- (root(383) /12)i
Q5: (3x - 2) * ( 2x + 3)
Answer:
The value of x will be:
Step-by-step explanation:
Given the equation
Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.
simplifying the equation by subtracting 14 from the L.H.S
Subtracting 15 from both sides
combining the like terms
dividing both sides of the equation by 5
Therefore, the value of x will be:
