" x/ 50 = 78/100 " ; in which "x" equals the number of points needed.
_______________________________________________________
To solve for "x" ;
_______________________________________________________
Look at the denominators: 50 * (what value?) = 100.
→ "100 ÷ 50 = 2" .
→ So; "50 * 2 = 100" ;
So, let us look at the numerators:
x * 2 = 78 ;
↔ 2x = 72 ;
Divide each side of the equation by "2" ; to isolate "x" on one side of the equation ; and to solve for "x" ;
_____________________________________________
→ 78 ÷ 2 = 39 ;
The answer is: "39 points" .

Answer:1188
Step-by-step explanation:
Answer:
Hey!
Your answer is 44!
Step-by-step explanation:
Here's how...
x+(x+2)+(x+4)+(x+6)+(x+8)=200
5x+20=200 (minus 20 on both sides to get 5x by itself)
5x=180 (divide both sides by 5 to get just x)
x=36
5th number - x+8=36+8=44 (simple substitution and addition)
