If your car gets 34 miles per gallon of gas and you have traveled 153 miles, how many gallons of gas have you used?

 4.5 gallons

Step-by-step explanation:

Given : The car run 34 miles per gallon of gas .

i.e. The car travels in one gallon of gas = 34 miles

Then, by applying UNITARY METHOD, if you have traveled 153 miles, then the number of gallons of gas have you used is given by :_

Therefore, the number of gallons of gas have you used = 4.5

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
