Answer:
Option B. .
Step-by-step explanation:
The given equation is kx - 4 = 9
We will add 4 on both the sides of the equation
kx - 4 +4 = 9 +4
kx = 13
Now we will divide by k on both the sides of the equation
Therefore Option B x = 13/k is the right answer.

Answer:
Hisaki can make 4 2/3 batches of cookies with 3 1/2 cups of sugar.
Step-by-step explanation:
Let x be number of batches with 3.5 cups. (I've converted the fractions to decimals to simply calculation. Let me know if you want an explanation where I retain the fractions as-is.)
1 batch = 0.75 cup
x batches = 3.5 cups
-using unitary method-
( 3.5 * 1 ) / 0.75 = x
4.66667 = x
Therefore, number of batches = x = 4 2/3 batches.
Step-by-step explanation:
Say y=ax+b. It goes through (0,8) and (4,0). Therefor we can say 8=a(0)+b which gives us b=8. Then we fill in (4,0) which results in 0=a(4)+8. Given that, a=-2. so y=-2+8
