Answer:
3/7 x +5=8
move 5 to the other side
3/7 x= 8-5
3/7 x= 3
then move 7 to the other side it's sign is ÷ it will be ×
then 3x=3×7
3x=21
then move 3to the other side it's sign is × it will become ÷
x= 21/3
x= 7
Answer: 90
Step-by-step explanation:
if you multiply the number of times the house played each opponent
Since They played each of their 15 opponents 3 times (keyword 3 Times so you don’t get confused again)
It would be 15x3=45 this answer “45” is the amount of games they played
Now you times it by 2
45x2= 90
W + (4.5 + 4w)= 60
5w + 4.5 = 60
5w = 55.5
w = 11.1
l = 11.1 + 4.5 + 4(11.1)
solve for l to find the length
sorry i half did this. i’m really tired :D hope i helped in something, even tho i could be wrong F
