Answer:
Therefore (x,y)=(3,7)
Step-by-step explanation:
put the second equation into the first
x+4=3x-2
x-3x=-2-4
-2x=-6
x=3
plug x=3 into the second equation
y=3+4=7
Answer:
7 < y
Step-by-step explanation:
The relation you're interested in is ...
(4.5 -2y)/5 < (2 -3y)/10
9 -4y < 2 -3y . . . . . . . . . multiply by 10
7 < y . . . . . . . . . . . . . . . . add 4y-2
The value of the first fraction will be less than that of the second fraction for values of y greater than 7.
Answer:
It should be "The unit rate is 2/3 every 1 hour" everything else is correct.
Step-by-step explanation:
Answer:
divide each term in the equation by the coefficient or multiply each term by the reciprocal of the coefficient
Step-by-step explanation:
1.<span>Since x is equal to both 4y+5 and 3y-2</span><span>
You can say 4y+5=3y-2 y=-7
