Answer:
Infinitely many solutions
Step-by-step explanation:
If we have a system of equation like:
2x+y=4
6x+3y=12
If we make y the subject in the first equation and substitute into the second equation, we get:
6x+3(4-2x)=12
We expand to get:
6x+12-6x=12
6x-6x+12=12
Now the variable adds out to give:
12=12
This statement is true so the equation has infinitely many solution.

Answer:
The entire race is 26.20 miles long.
Step-by-step explanation:
Given that:
Sam is 18.34 miles in the race.
This length represents the 70% of the entire length of the race.
Let,
x be the total length of the race.
70% of x = 18.34
0.7x = 18.34
Dividing both sides by 0.7
Hence,
The entire race is 26.20 miles long.
Answer:
C. White Fangs bond with his mother
Step-by-step explanation:
Answer:
cost per gram of small bag ≅ 4.119 p
cost per gram of medium bag ≅ 3.686 p
cost per gram of large bag ≅ 3.517 p
Step-by-step explanation:
cost per gram of small bag = 325 / 79
= 4.119
cost per gram of medium bag = 575 / 156
= 3.686
cost per gram of large bag = 1150 / 327
= 3.517
