Answer:
B) addition property
Step-by-step explanation:
thinking that 3x - 30 - 0 should equal 0.
3x - 30 - 0 = 0
to get rid of numbers on side with variables, we have to add them to both sides (to make it 0 in side with variable.)
3x - 30 - 0 = 0
+30 +0 = +30 +0
3x = 30 <- step 4
Answer:AB= 1.0
AC=1.0
BC=1.4
Step-by-step explanation:
Answer:
A is 10.0 inches.
B is 35 inches.
Step-by-step explanation:
To find the answers, we can just multiply our original lengths by our scale factor.
Our original width is 8 inches.
This means that our new width, A, will be our old width multiplied by our scale factor.
So:
Similarly, for our length, our old length is 28 inches. This means that our new length is:
And we're done!
Answer:
y = 400 - 50x
Step-by-step explanation:
From Minneapolis to Chicago = 400 miles
Speed of travel = 50 miles per hour
y = distance ; x = time
Distance = speed * time
Distance moved before stopping for gas:
50 * x = 50x
y = distance left to cover ;
400 m = total distance
50x = distance already moved
Therefore,
y = 400 - 50x
