Here, you just want to solve for b. because the right side of the equation doesn't have any like terms, you have to factor that b out:
s = ab - bc
s = b(a - c)
divide both sides by (a - c)
s/(a - c) = b is your answer. it's "s" over "a - c" if the formatting is difficult to read
To determine the ratio of the lengths of the red and blue ribbon, we just have to divide the lengths of the corresponding colored ribbon.
red / blue = 3/4 / 2/3 = 9/8
(2) The ratio of the lengths expressed as a unit rate is 9/8:1
(3) The ratio of the lengths of the blue to red ribbon is the reciprocal of the calculated value above giving us the answer of 8/9.
7 x 24 = 168 hours a week
168 x 60 = 10,080 minutes a week
10,080 x 60 = 604,800 seconds in a week
Answer:
(-4, 6), (0, 2), (4, -2). You can find this by adding the x and y to see which ones get 2. -4 + 6 = 2. 0 + 2 = 2. 4 + -2 = 2.
