Hello from MrBillDoesMath!
Answer: b
Discussion:
7b + 3 - 4b = 3 - 3(b+4) =>
7b + 3 - 4b = 3 - 3b -12 =>
(7b - 4b) + 3 = -3b - 9 =>
3b + 3 = -3b -9 => Add 9 to both sides
3b + 12 = -3b -9 + 9 =>
3b + 12 = -3b => ( add 3b to both sides)
6b + 12 = 0 => (subtract 12 from both sides)
6b = -12 =>
b = -12/6 = -2
Thank you,
MrB
HI
LET ME HELP YOU WITH YOUR QUESTION
1 kg = 1000 grams
Since 1kg = 1000 grams then 65 kg will = 65000 grams
hope it helps
Use a number line if you need 4/10 - 6/10 = -2/10a simpler way is to do the opposite 6/10 - 4/10 = 2/10 then the answer would be the opposite as well. so, -2/10
Plug 4 for x and solve.
y = -3/4 * 4 + 3
y = -12/4 + 3
y = -3 + 3
y = 0
So the missing coordinate is 0.
