Plug in the point for each equation:
x=1/4y + a
(1)=1/4(2) + a
1=1/2+a
1/2=a
y=1/4x+b
2=1/4(1) +b
b= 7/4
Solve a+b:
a+b=?
(2/4)+(7/4)= 9/4= 2.25
24 3/4 divided by 1 3/8 equals 18
You can use the formula
speed=distance/time
20.88=145/x
x=145/20.88
x=6.9 hours -it will take 9 hours
Do 3.7 / 10, since metric units are 10 in comparison, and you get 37 decimeters , which in turn, you divide again by 10 to get centimeters, so 370 centimeters.
Then add 45 to that to get 415 centimeters. Then multiply that by 100 to get back to meters, so 4.15 meters
For every 1 vanilla 4 are sugar???????? Im guessing
