Answer:
<u>So option 4; </u>
<u> is the correct option</u>
Step-by-step explanation:
First, we need to convert
so it's denominator is 100. To do so, we will multiply the numerator and denominator by 10

Second, we need to add the two fractions to get the current total distance walked. Remember, when adding fractions, the denominator does not change.

Now that we have the total distance walked, we need to subtract that to 1 mile. 

So option 4;
is the correct option
Answer:3
Step-by-step explanation:
If triangles PQR and STU are similar then PQ corresponds to ST and PR corresponds to SU. Therefore, PQ/ST=PR/SU
Considering that, PQ= 7-x, ST= 13-x, PR= x²+5 and SU= x² +20
therefore, (7-x)/(13-x)= (x²+5)/(x²+20)
cross multiplying,
7x² +140-x³+20x =13x²+65-x³-5x
combining the like terms,
6x² +15x -75=0
solving for x,
x = 5/2 or -5
