X , y = 0
0 = 2x - 10
2x = 10
x = 5
Answer:
A: 10,000 residents to 25 police officers
Step-by-step explanation:
400*25=10,000
Answer:
Step-by-step explanation:
L=4W+8
P=2(L+W)
P=2(5W+8) and P=476
2(5W+8)=476
5W+8=238
5W=230
W=46yds
L=4(46)+8=192yds
So the dimensions are 46X192 yards
4 gallons of water is needed to dilute to a concentration of 10%.
<u>Step-by-step explanation:</u>
It is given that,
The 5 gallons of water contains 18% of acid solution.
Now, we are asked to find the gallons of water needed to dilute it to a concentration of 10% acid solution.
We obtain the equation by stating that the amount of acid 10% in the water must dilute up to 18%.
For this, x amount of water should be added.
Therefore, the equation is framed as,
⇒ 0.1 (x+5) = 5 (0.18)
⇒ 0.1x + 0.5 = 0.9
⇒ 0.1x = 0.9 - 0.5
⇒ x = 0.4 / 0.1
⇒ x = 4
∴ 4 gallons of water is needed to dilute to a concentration of 10%.
To solve the problem we should know about Expressions.
