7x+y-9=0
move constant to the left by adding its opposite to both sides. the sum of the two =0
Answer:
871
Step-by-step explanation:
737 divided by 11 is 67, so thats how many miles he drives per hour
67 times 13 is 871
The number in the ones place= X
The number in the tenths place= y
y+x=14.
y=14-x
Original placement of numbers=10y+x
New placement of numbers(after subtraction of 36)= 10x+y
10y+ x-36=10x+y
Substitute y with 14-x
So we would get
10(14-x)+ x-36=10x+(14-x)
=140-10x+x-36=10x+14-x
After transposing we get
140-14-36=10x-x+10x-x
=90=18x
X=90/18
x=5
Y=14-x
=14-5
=9
So the two digit number is
10y+x
=90+5
=95
$0.85
38.25/45= .85
TO CHECK
.85 times 45 equals 38.25
