$252/$28=9 lawns. $252 is the total money they earned, so divide it by the amount of money they charge per lawn.
Answer: - (4 1/4)
Solution:
(6 1/2 + 2 3/4) - 1.5*(4.5/0.5)=
(6 0.5 + 2 0.75) - 1.5*(9)=
(6.5+2.75) - 13.5=
(9.25) - 13.5=
- 4.25=
-(4 0.25)=
-(4 1/4)
Answer:
Step-by-step explanation:
Mid point of two points is given as
Let Point 1 be(x1,y1)
And point 2 be (x2,y2)
Then, mid point is given as
M = [ (x1+x2) / 2 , (y1+y2) / 2 ]
So, given that,
Point 1 =(4,5)
Then, x1=4 and y1=5
Point 2=(1,2)
Also, x2=1 and y2=2
Then, applying the formulae
M = [ (x1+x2) / 2 , (y1+y2) / 2 ]
M = [ (4+1) / 2 , (2+5) / 2 ]
M = [ 5 / 2 , 7 / 2 ]
Then, the midpoint is
M=(5/2, 7/2)
To decimal point
M=(2.5 , 3.5)
To mixed fraction
M=(2½, 3½)
(x, y)=(2½, 3½)
Standard form (which I assume is what they want you to turn these into) is y=mx+b.
12x-5y=20 is y=2.4x-4.
Subtract 12x from both sides, -5y=-12x+20.
Multiply both sides by -1, 5y=12x-20.
Divide both sides by 5, y=2.4x-4.
y=x+4 is already in standard form- I'm not quite sure what to do.
3x+y=3 is y=-3x+3.
Subtract 3x from both sides, y=-3x+3.
x=-y+3 is y=-x+3
Ad y to both sides, y+x=3.
Subtract x from both sides, y=-x+3.
Breanna exercises for 4 and 1/2 hours during the six days.
To find the answer, we have to multiply 3/4 by 6.
To do this, we change 6 to 6/1 and multiply straight across.
3/4 x 6/1 = 18/4 = 9/2
9/2 is the same as 4 and 1/2
