slope m = - 2 → B
calculate m using the ' gradient formula '
m = (y₂ - y₁)/(x₂ - x₁)
choosing 2 'clear ' coordinates from the graph of the line
(x₁, y₁) = (0, 7) and (x₂, y₂) = (7, - 5
) =
= - 2
m =
Lets round each distance to the nearest tens place, and then add them up to get an estimate. 143 rounds down to 140, 138 rounds up to 140, and 141 rounds down to 140. So: 140 + 140 + 140 = 420 miles
Answer:
1.75 × 10^3
Step-by-step explanation:
4x10^6=4000000
7x10^9=7000000000
7000000000 divided by 4000000 = 1750
1750=1.75 x 10^3
Answer:
100
Step-by-step explanation:
43+57=100
I added 3+7=10
Then 40+50=90 and added them
90+10=100
