Answer:

So the maximum amount of gasoline the tank can contain is 13 gallons and there are already 7 gallons of gasoline in the tank. Therefore, we want to make sure that the amount of gasoline put in the tank doesn't reach any higher than 13 gallon.

The amount of gasoline that Lou bought with x dollars is x/2.50 gallons.

We have the inequality:

x/2.50 + 7 ≤ 13

*If you solve it, x should be smaller or equal to $15.

Given: y ll z

Answer:

As per the properties of parallel lines and interior alternate angles postulate, we can prove that:

$m\angle 5+m\angle 2+m\angle 6=180^\circ$

Step-by-step explanation:

Given:

Line y || z

i.e. y is parallel to z.

To Prove:

$m\angle 5+m\angle 2+m\angle 6=180^\circ$

Solution:

It is given that the lines y and z are parallel to each other.

$m\angle 5, m\angle 1$ are interior alternate angles because lines y and z are parallel and one line AC cuts them.

So, $m\angle 5= m\angle 1$ ..... (1)

Similarly,

$m\angle 6, m\angle 3$ are interior alternate angles because lines y and z are parallel and one line AB cuts them.

So, $m\angle 6= m\angle 3$ ...... (2)

Now, we know that the line y is a straight line and A is one point on it.

Sum of all the angles on one side of a line on a point is always equal to $180^\circ$ .

i.e.

$m\angle 1+m\angle 2+m\angle 3=180^\circ$

Using equations (1) and (2):

We can see that:

$m\angle 5+m\angle 2+m\angle 6=180^\circ$

Hence proved.

3(2x+1)=21 Solve this multi-step equation using the distributive property

Tasya [4]

3 (2x + 1) = 21
6x + 3= 21
-3 -3
6x = 18

Divide each side by 6, and x equals 3.

3 (2(3) + 1) = 21
3 (6 + 1) = 21
18 + 3 = 21

Hope this helps! Can I please have brainliest so I can level up? Thank you!
