Answer:
y=3x-2
Step-by-step explanation:
your question didn't have any instructions so this might not be what you're looking for
set them equal to each other
-3x+4=3x-2
-3x-3x=-2-4
-6x=-6
x=1
plug in x=1
y=3(1)+4 =7
y=3(1)-2 =1
so, when x=1, y=1 in the expression y=3x-2
Answer: the answer is right, try putting a $ in front of it, sometimes those programs mess up if you aren't specific
Huh? this is very confusing 12
Answer:
Step-by-step explanation:
s=rtheta
s/r=theta
11.5/25=theta
theta=.46
This is the concept of algebra, to calculate the proportion of wool in each item we proceed as follows;
Let the amount of wool used for hat be x
amount of wool in sweater will be 5x
the amount of wool used in scarf will be x-5
therefore the total amount of wool will be:
x+5x+(x-5)=550
x+5x+x-5=550
7x-5=550
7x=550+5
7x=555
hence;
x=555/7
x=79
the amount used in hat x=79g
amount used in sweater 5x=395g
amount used in scarf=79-5=74g
