Answer:

x > 2

Step-by-step explanation:

9x > 18

In solving this inequality, we divide both sides of the inequality sign by the coefficient of the unknown variable, 9

9x/9 > 18/9

x > 2

An important thing to note in solving an inequality is that when you are dividing an inequality by a negative number, the inequality sign changes that is, a greater than sign, > changes to a less than sign, <.

The solution of the inequality is therefore,

x > 2, read as x is greater than 2

If your car gets 35 miles per​ gallon, how much does it cost to drive 400 miles when gasoline costs ​$3.30 per​ gallon?
Arlecino [84]
To solve his equation start by finding how many gallons of gas you need to purchase for the total trip.
Set up an expression that divides the total distance of the trip by the miles received per gallon.
This gives you:
400 / 35

Divide to get 11.43 gallons.

To find the cost of this, multiply the total number of gallons needed to cover the trip by the cost of each gallon.
Set this up in another expression.
This results in:
11.43 x 3.30

Multiply the values to find the total cost.
This leaves you with:
37.72

So, the total cost for gas for a 400 mile trip on 35 miles per gallon is $37.72.

I hope this is correct and helps you! :)

Answer:

A

Step-by-step explanation:

It says the both dimensions are 30%. So, it we do 31 divided by 6, it would be 5 with a remainder of one, which is also equal to 5.1. If we then multiply it by 4, then divide by 9, that would be .03.

Lana71 [14]

Let rajus age be x

  • His father=3x+5

ATQ

\\ \bull\tt\longmapsto 3x+5=50

\\ \bull\tt\longmapsto 3x=50-5

\\ \bull\tt\longmapsto 3x=45

\\ \bull\tt\longmapsto x=\dfrac{45}{3}

\\ \bull\tt\longmapsto x=15
