Answer:
(16)(1) => identity property of multiplication
2(3+7) = 2(3) + 2(7) => distributive property
(2+6) + 3 = 2+ (6+3) => associative property
9+0 = 9 => identity property of addition
8 x 4 = 4 x 8 => commutative property
Ok, to solve this first you have to set up your proportion:
9/150=x/230
/ is a fraction
x= the number of vials it will take to treat 230 patients
in order to solve this, you have to cross multiply:
9 x 230= 2070
150 · x= 150x
so you get 150x=2070
then divide 2070 by 150
2070/150= 13.8
so it would take 13.8 vials of medicine to treat 230 patients
Answer:
w > 9
Step-by-step explanation:
Solve the inequality by using inverse operations.
-4w - 2 < -38
-4w < -36
w > 9
Like solving equations, inequalities should be solved using inverse operations. However, unlike equations, when you divide or multiply by a negative the sign changes.
Answer:
80 miligrams
Step-by-step explanation:
100 / 250 = 0.4
0.4 * 200 = 80
A + s = 480......s = 480 - a
8a + 5s = 2892
8a + 5(480 - a) = 2892
8a + 2400 - 5a = 2892
8a - 5a = 2892 - 2400
3a = 492
a = 492/3
a = 164 <=== there were 164 adult tickets sold
