Unit rate means one. So the best way to solve this is using a proportion over one. If there are 258 pencils in 3 purses 258/3 then how many are in one purses x/1. Cross multiply next.
258/3 * x/1. You get 3x and 258. To get the x alone, divide both sides by three. Your answer is 86 pencils in one purse.
Step-by-step explanation:
that's the answer bbbbbbbb
-4x + 10y = -4
10y = 4x - 4
y = 2/5 x - 2/5 so slope = 2/5
-2 - 2x = 5y
5y = -2x - 2
y = -2/5 x - 2/5 so slope = -2/5
the slope is opposite so the lines are intersecting
answer is A.
Answer:
A: 34 degrees
B: 102 degrees
Step-by-step explanation:
Complementary angles = 90 degrees
Supplementary angles = 180 degrees
(a) 90 - 56 = 34
(b) 180 - 78 = 102
