Answer:
b,c,d
Step-by-step explanation:
First find how many units of solution there is:
500* 2% = 500(.02) = 10 units
You need 10 units of solution in 'x' units of a 10% solution.
x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100
100 units are needed
1/10 of .9 is the same as dividing .9 by 10.
.90 / 10 = .09
.09 is the answer
Going side to side(horizontal) is always length and going up and down (vertical) width
Answer:
Step-by-step explanation:
(x+2)/2 = 0
x + 2 = 0
x = -2
(y - 3)/2 = 2
y - 3 = 4
y = 7
(-2, 7)
