It would be 15-5=10 that is because you subtract q3-q1
The correct answer would be D. because if the equation has a y-intercept (+4) than the line doesn't go through the origin.
Answer: 2.55 (or 51/20) kilometers
Step-by-step explanation: 17/5 km per one hour is 51/20 (2.55) km per 3/4 hours
Number 1 is:
C and E
Number 2 is:
400
3x-13=2
move -13 to the other side
sign changes from -13 to +13
3x-13+13=2+13
3x=2+13
3x=15
divide both sides by 3 to get x by itself
3x/3=15/3
cross out 3 and 3, divide by 3 and then becomes 1*1*x=x
x=15/3
x=5
answer:
x=5
