Answer:
There will be 19 trees left over after planting.
Step-by-step explanation:
Divide 1384 by 21 which gives you the quotient of 65.90...
Then multiply 65 by 21 which equals 1365
Lastly subtract 1384 and 1365 which gives the answer 19.
(3y+40)+(3x-70)=180
3y+3x-30=180
3y+3x=210
3(y+x)=210
y+x=70
x=70-y
meanwhile 180-120=x therefore x=60
therefore
60=70-y y=10
so x=60 y=10
Because 60 seconds= 1 minute and then 120 seconds=2 minutes, u multiply 10 ×12 to get to 120 seconds and then u multiply 4×12 which equals the answer which is 48.
Answer:
(-3 ,2.5)
Step-by-step explanation:
midpoint formula is
x1+x2 y1+y2
(___ , _____ )
2 2
(-7,-2) -7 is x1 i.e the first x point and -2 is y1 1st y point
(1,7) 1 is x2 i.e the second x point and 7 is y2 the second y point
now we use input the numbers to the formula
-7+1 -2+7
(____ , --------)
2 2
we the signs are different you subtract and use sign of greater number
-6 5
__ , ___
2 2
Now you divide
and here is the ordered pair for midpoint.
(-3 ,2.5)
