Alrighty!
*Note the ">" sign is similar to the "=" sign.
3m - 3(3m + 8) > 3m
3m - 6m + 24 > 3m (distribute)
-3m + 24 > 3m (combine like terms)
24 > 6m (Compute/simplify)
8 > m
Makes sense?
4x-(5-x)=8[4-(8+2x-1)]
answer: x= -19/21
Answer:
t = -6.25
Step-by-step explanation:
3/4 (184+t) =237
multiply by 3/4
184 + t = 177.75
subtract 184
t = -6.25
Answer:
He/she grew 0.3 meters so 1.8m
Step-by-step explanation:
I just did the math
When you set up equations like this, look at the units for help. They cancel out during division and multiplication like numbers to give desired quantities. Rates can be reversed if need be (3 meters/sec or 1/3 sec/meter).
time × (distance / time) = distance
See.. time/time = 1; leaving distance
Subtract the rate of the opposing walkway...
t × (3 m/s - 1 m/s) = d
2t = d
Answer is then A.
