12 - 3 =9 and -5i+4i=1i or i so it is {9-i}
Answer:
Yellow = 18 spools of ribbon
Blue = 15 spools of ribbon
Bobby will have 3 more spools of yellow ribbon.
Converting this into an equation, we get:
6x+4y=14
-8x-4y=-12
We can solve this by adding the system of equations.
6x+4y=14
+ -8x-4y=-12
-------------------------
-2x=2
Simplifying, we get that x=-1. We can replug this into one of the equations to get y. We'll choose 6x+4y=14
Plugging in -1 for x, we get that:
6(-1)+4y=14
which is
-6+4y=14
which is
4y=20
Simplify this to get that y=5
To check, you can plug in x and y into both equations to make sure that they are true.
6(-1)+4(5)=14
-6+20=14
14=14 which is true
-8(-1)-4(5)=-12
8-20=-12
-12=-12 which is true
x=-1 and y=5

Answer:
first you add all the candies together to get 20 in the bag
2+11+7=20
jelly treat:
now we divide 11 by 20 to get a decimal
11/20= .55
multiply .55 by 100 to change it to a percentage
.55*100=55
first part of answer: He has a 55% chance of getting a jelly treat
mint stick:
divide 2 by 20 to get a decimal
2/20=.1
change .1 to a percent by multiplying by 100
.1*100=10
second part of answer: he has a 10% chance of getting a mint stick
Step-by-step explanation:
Well for every ten packs Jason paid $16 ($64/4). If he charges his friend what he was charged, he would charge $16 for 10 packs :)
