Answer:
15/4
Step-by-step explanation:
(-5,-10) and (-1,5)
y2-y1/x2-x1
5+10 / 4
15/4
Running laps and timing them
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.
If the interst rate is 2% per year and she paid it back after 3 years , it means she paid an extra 6% of $2000 just in interests.
Now we just need to find how much 6% is and add to 2000.
to discover the value of 6% of 2000 we can divide it by 100 ( to find 1%) and then multiply it by 6 ( to find 6%) :
2000 ÷ 100 = 20
1% = 20
6% = 20 × 6
6% = 120
Now add 120 to 2000 to find out how much she paid in total:
2000 + 120 = 2120
Awnser : She paid the total of $2120 over 3 years
I hope you understood my brief explanation. And please consider marking this awnser as Branliest. Thank you ! :)
