−0.5454546
this is my answer
Step-by-step explanation:
go right 4
go down 3
it is the answer
The answer is B-about 18km
This is because you round 18.23 to 18km
then you round 13.94 to 14km
you add these rounded numbers together
you take it away from 50km
the answer would then me 18km
but it be ABOUT because that was only a rough estimate because it was rounded
Answer:
-7
Step-by-step explanation:
Answer:
x=4 and y=2
Step-by-step explanation: Step 1: Solve x+3y=10 for x:
x+3y=10
x+3y+−3y=10+−3y(Add -3y to both sides)
x=−3y+10
Step 2: Substitute−3y+10for x in2x+2y=12:
2x+2y=12
2(−3y+10)+2y=12
−4y+20=12(Simplify both sides of the equation)
−4y+20+−20=12+−20(Add -20 to both sides)
−4y=−8
−4y
−4
=
−8
−4
(Divide both sides by -4)
y=2
Step 3: Substitute 2 for y in x=−3y+10:
x=−3y+10
x=(−3)(2)+10
x=4(Simplify both sides of the equation)
So your answer would be x=4 and y=2
Hope this helps
