The problem express that the fraction of time
worked by the three people need to be equivalent to one person working full
time. This means that the fraction need to add up to one. We know one person
works ½ time on the project and another works one third 1/3 time.
Given:
A = the amount of time that the third person needs
to work on the job to add up to one
1 = ½ +1/3 + A
1 – ½ - 1/3 = A
To subtract the fractions put them all over a
common denominator. Use 3 * 2 as the denominator.
1=6/6, ½ = 3/6, 1/3 = 2/6
A = 6/6 – 3/6 – 2/6
<span>A = 1/6 , The third person must work on the project</span>
Y = mx + b
-3 = 1/2(-2) + b
-3 = -1 + b
b = -2
equation
y = 1/2x - 2
standard form
1/2x - y = 2
or
x - 2y = 4
Answer:
6+x with x equalling the amount of coins bought if that is what you were looking for
Step-by-step explanation:
if you want to make and equation out of this you don't know the amount of coins she bought so you use a variable (x) to replace that unknown number then since it says she bought more she is adding more to her collection which means it would be an addition problem, leaving you with 6+x for your final answer
It’s positive 2 because if u add or subtract two negative numbers it comes out positive I’m pretty sure
Answer:
6 : 1
Step-by-step explanation:
divide by 3 on both sides
18 ÷ 3 = 6
3 ÷ 3 = 1
6:1
