Answer:
a variable is an unknown number, the point of algebra is to solve for the. they are represented by letters, 5x is an example.
Step-by-step explanation: skillz
I would help but i don’t see a figure
M(h)=5h
that is marcia's number of candles where she makes 5 candles per hour (h)
kevin makes 4 but already did 7 so
k(h)=4h+7
when will they have same numbre of candles?
when will m(h)=k(h)
set equal
5h=4h+7
minus 4h from both sides
1h=7
answer is 7 hours
system of equation is
m=5h
k=4h+7
find what value of h makes m=k true
answer is 7 hours
ФThe Answer is A).the first graph i know this is the correct Answer.Ф
No. only elena is correct
explanation: in order to solve the equation you first need to subtract 2d from both sides so it’ll look like this
8d-2d = 2d-2d
then you need to combine like terms (the new terms you added are both negative so it cancels out the right side) and it’ll look like this
6d = 0
finally, to find d, divide both sides by 6 because its being multiplied by d
6d/6 = 0/6
zero divided by anything is zero so you are left with:
d = 0
