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.
Add 1/4 and 2/3 and then 3 and your answer wll be 28 3/4
Answer:
What are we supposed to solve??? its incomplete
Step-by-step explanation:
Answer:
Mary would have 618 pieces of candy.
Step-by-step explanation:
You would add 432 and 186, which gives you 618. (use a calculator to double check. it helps)
To round off the value of 155, 016 to the nearest thousands,
we can first elaborate the given to its expanded form which is:
100, 000 + 50, 000 + 5, 000 + 10 + 6 = 155, 016
<span>Since the nearest thousands is in the value is 5, 016 and the
next number is 0 the number shall be 155, 000. Notice the rounding principles,
0-4. </span>
