Answer:
First of all this question makes no complate sense if this was in real life. But the answer is: Allen is 23 years old and Jim woukd be 12 1/2 years old.
Step-by-step explanation:
Because 20+3=23. That's because it said in 3 years. Tthen we divide by 2 to find Jim's age. That's because it said that in three years, Allen would be twice as old as Jim.
Salinas will use 32 gallons for 480 miles
<h3>How to calculate the number of gallons required ? </h3>
Salinas used 15.6 gallons of gas for 234 miles
Miles can be described as the distance travelled by an object or an individual
The first step is to calculate the number of miles travelled using 1 gallon
15.6= 234
1= x
cross multiply both sides
15.6x= 234
x= 234/15.6
x= 15
1 gallon will take her 15 miles
Therefore, the number of gallons required for 480 miles can be calculated as follows
1= 15
x= 480
cross multiply both sides
15x= 480
x= 480/15
x= 32
Hence Salinas will require 32 gallons for 480 miles of the journey

Sentence one uses<span> the </span>simple past<span> tense. Sentence two </span>uses<span> the </span>present perfect tense<span>. “I saw the movie” and “I have seen the movie” both refer to an action that was finished in the </span>past<span>. But there is one important difference: “I saw the movie” suggests that you saw the movie at a specific time in the </span>past<span>.</span>
we know that
<u>in the triangle PQR</u>
m∠PQR+m∠QPR+m∠QRP=180°------> the sum of the internal angles of a triangle is equal to 180 degrees
(m∠PQR+m∠QRP)+74°=180°-------> (m∠PQR+m∠QRP)=106°
we know that
If QS and SR are angle bisectors
then
<u>In the triangle QSR</u>
m∠SQR+m∠QSR+m∠QRS=180°-------> equation 1
and
(m∠SQR+m∠QRS)=106°/2--------> (m∠SQR+m∠QRS)=53°
substitute the value of (m∠SQR+m∠QRS)=53° in the equation 1
53°+m∠QSR=180°
m∠QSR=180°-53°-------->m∠QSR= 27°
therefore
<u>the answer is</u>
The measure of angle QSR is 27 degrees
