If its improper fraction is 11/7 if you want the mixed number its 1 4/7
There's a special case of the quadratic formula called the Shakespeare Quadratic Formula (2b or -2b) that applies when the linear coefficient is even.
If you're planning on solving a lot of quadratic equations quickly, it's good to know.
Here we have
so
Answer:(2,1/3)
Step-by-step explanation:
-x-3y=-3
2x+3y=5
_________First solve for x since y is 0. -3y+3y=0
1X = 2
1x/1= 2/1
X= 2
Now substitute your x answer into any equation to find y I used second equation
2x+3y= 5
2(2)+3y=5
4+3y=5
3y=5-4
3y=1
3y/3=1/3
Y=1/3
Answer:
Capacity of 60000 litres "to 1 significant figure" means that lower bound is 54449, upper bound is 64999.
=> 10% of that capacity is more than 54449/10 = 5444.9 litres
Tony pours in 5400 litres of water "to 2 significant figure" means that lower bound is 5349, upper bound is 5444.
Because 5444<5444.9, then clearly he is not correct when he said " I have filled more than 10% of the container"
Xb + xr + xc = m
X being the amount of supplies
B are the price of the brushes
R is the price of the rollers
C the price of the paint cans
M is the total price
