Answer:
The answer is -18
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
Lets find the rate of selling:
Let v= the rate of selling, b = number of bottles of water, and t = time:
b over t gives us the
rate of selling:
3 hours is 60min * 3 = 180 mins, and since v=b/t, vt=b:
(0.15) * 180 = 27 bottles of water
Answer:
x = -6
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
2(x - 7) = 5x + 4
Step 2: Distribute parenthesis
2x - 14 = 5x + 4
Step 3: Subtract 2x on both sides
-14 = 3x + 4
Step 4: Subtract 4 on both sides
-18 = 3x
Step 5: Divide both sides by 3
-6 = x
Step 6: Rewrite
x = -6
Answer:
<h2> 52 chickens</h2>
Step-by-step explanation:
Step one:'
given
we are told that the total number of animals is 169
the ratio of horses to chickens= 9:4
total ratio= 13
Required:
number of chickens
Applying part to all principle, let the number of chickens be x
4/13=x/169
cross multiply
4*169=13*x
divide both sides by 13
x=4*169/13
x=676/13
x=52
There are 52 chickens
