Both 25x and 22x + 9 have the same answers. So you set those two equal to each other.

Subtract 22x from both sides.

and you're left with this.
Next, divide 3 from both sides.

re-insert 3 into one of the equations.

add up both angles

all angles (for quadrilaterals)added up equals 360.

solve for x. Subtract 150 from both sides.

and divide 2 from both sides

AngleLMN= 105
Answer:
$146
Step-by-step explanation:
54.75= 3 hrs
divide both sides by 3
18.25= 1 hr
multiply both sides by 8
$146= 8hrs
Given
Ravi has $445 in his savings account.
He wants to save at least $795.
Write and solve an inequality to determine how much more money Ravi must save to reach his goal.
To proof
As given
amount of money in dollars Ravi must save to reach his goal be = d
Ravi has in his savings account = $445
He wants to save at least $795
than the inequality become in the form

thus $350 Ravi must save to reach his goal.
Hence proved
Answer:
80 km/hr
Step-by-step explanation:
This is asking for speed.
Speed=Distance/Time
Speed=720/9
Speed=80 km/hr
