2 1/2, 3, 3 1/2, 4, 4 1/2, 5
I hope this helped!!:)
True, u can choose any two distinct points on a line to calculate the slope
Answer:
B. Alternate interior angles
Step-by-step explanation:
<4 and <5 are inside the parallel lines on alternate sides of the third line.
That would be D
the first 3 = -12x + 24
bur D = -12x - 24

Answer:
- 100 mL of 75% solution
- 150 mL of pure alcohol
Step-by-step explanation:
Let x represent the quantity (in mL) of pure alcohol needed for the mix. Then the amount of 75% needed is (250-x). The amount of alcohol in the mixture is ...
1.00x +0.75(250 -x) = 0.90(250)
0.25x +187.5 = 225 . . simplify
0.25x = 37.5 . . . . . . . . subtract 187.5
x = 150 . . . . . . . . . . . . . divide by 0.25
(250 -x) = 100 . . . . mL of 75% solution
You need 100 mL of the 75% solution and 150 mL of pure alcohol to obtain the desired mixture.
