Answer:

39 touchdowns and 13 fieldgoals

Step-by-step explanation:

Let t= touchdowns

f = fieldgoals

They scored 35 times

t+f = 35

Touchdown is 7 pts and fieldgoal is 3 pt

7t+3f = 193

Multiply the first equation by-7

-7t -7f =-245

Add this to the second equation

-7t -7f =-245

7t+3f = 193

----------------------

-4f =-52

Divide by -4

-4f/-4 = -52/-4

f = 13

Now we can find t

t+f = 35

t+13 = 52

Subtract 13 from each side

t+13-13 =52-13

t =39

An Ivy League college accepts 5 students for every 100 that apply. What fraction of applicants is accepted? Write your results i

Law Incorporation [45]

Hello there!

To find the fraction of applicants that are accepted into the Ivy League college, all you have to do is put the number of students accepted (numerator) over the total number of students that apply (denominator). This makes the fraction 5/100. This fraction can be simplified. To simplified, find the GCF of the two numbers. The GCF of 5 and 100 is 5. Divide both parts by 5. 5/100 ÷ 5/5 is 1/20. There. 5/100 is 1/20 in simplest form. The Ivy League college accepts 1/20 of it's applicants.
