20/ 7
7 goes into 20, 2 times oh whatever the answer is
2 and 6/7
Answer:
The value of a is 3
Step-by-step explanation:
First you have to make an equation based on the point and slope that you were given. The formula for this is y-(y cordinate of point)=slope(x-x cordinate of slope)
y--2=-3(x-6), which simplifies to y+2=-3(x-6)
In (a,7), 7 is the y coordinate. We have to plug 7 in for the y in our equation.
7+2=-3(x-6),
Combine like terms on the left side to get to 9=-3(x-6)
Multiply out on the left to get 9=-3x+18
Subtract 18 from the left side to get -9=-3x
Divide both sides by negative 3 to get 3=x (remember x is a)
Find the 2 different rates at which the farm worker worked:
3 pints
--------- = 0.75 pint/min
4 min
2 pints
---------- = 0.67 pint/ min
3 min
Then you need to subtract 0.67 pint/min from 0.75 pint/min to answer this question.
Alternatively, subtract 2/3 pint/min from 3/4 pint/min.
Use distributive property
5k - 6k -8 = 5x + 4
Combine like terms
-k - 8 = 5x + 4
add 8 to both sides
-k = 5x + 12
k = -5x- 12
