How do you think we should begin?
i honestly have no idea
So a systems of equations solves for when two things are the same, in this case when the number of bracelets made is equal
am i using subsitution
how many has brad made?
im guessing 4
it says she can make 4 in an hour. so every hour is 8 key chains.
Brad makes 4 per hour, so the number of keychains after x hours is 4x. Velma makes 3 per hour, so her number should be 3x, but she started with 6, so we must add that.. After x hours, she will have made 6 + 3x, while brad will have made 4x To solve when the number of bracelets will be the same, we will have to find x. The # of bracelets will be equal when both equations equal each other, so when 3x + 6 = 4x
Solve the equation
how is it 8 keys if every hour is 4
what i mean is every hour if you add 4+4 thats 8.
the answer would be 6
what you mean is every i houre she/he makes 4 and if you add 4+4 it =8. and when he makes 8 that is an equivilant of one hour
i get that
ok how bout this. 4x1=4 4x8=32
okay what does that have to do with the problem
it means in one hour he will have 4 in another hour he will have 8
so what would be the answer to the problem?
in words please:/
in words please:/
ok ill translate
its probilly 18 im not 100% sure
lol ill take whatever at this point
lol me to
You start by reading Brad can make 4 key chains in an hour. and this sentence Explain to Brad how he can use a system of equations to determine when he will have the same number of key chains as Velma. "when he will have..." means they want us to find time (in hours) if we want to find hours, give it a "name" like "x" x is the number of hours when both people have the same number of chains.
Now back to Brad can make 4 key chains in an hour. if Brad works for 1 hour, how many chains will he make? if he works for 2 hours? for 3 hours? for x hours? (you get the answer by multiplying rate * time, or in this case 4 * x) if you let y be the name for "number of chains", you write y=4x and that is short for y (number of chains) is 4 times number of hours worked
now try to do the same kind of thinking for Velma Velma can make only 3 key chains in an hour, but she already has 6 completed key chains.
