His moped needed 1.2 gallons of gas (5.03/4.19=1.2004 rounded to 1.2)
Answer: the first option
Step-by-step explanation:
If y=2x+4 and y also equals 3x+1, then by the transitive property, 2x+4=3x+1
It’s like saying if a=b and b=c, then a=c (that’s the transitive property)
1st 2nd 4th ones are correct
Let the two numbers be x and y
x/y=3/4
Therefore x=3z
y=4z, where z is the GCF of x and y
(3z+k)/(4z+k)=4/5
(3z+k)*5=(4z+k)*4
15z+5k=16z+4k
k=z--->eq1
3z+k+4z+k=117
7z+2k=117--->eq2
Using value of z from eq1 in eq2
7k+2k=117
k=117/9
