The first expression can be simplified by combining like terms.
First, the terms "4b" and "-3b" can be combined to form "b"
Then, the terms "-7" and "9" can be combined to form "2"
Finally, we simply put these two final terms together, to form "b+2"
Hence, 4b-7-3b+9 is equal to be + 2.
Hope this helps!
Answer:
y=-2
Step-by-step explanation:
in other words, the question is asking
"six time what plus four equals 12?"
we know that 6 ⋅ 2 = 12
therefore if we plug the -2 into the Y we get
6(-2+4)=12
6(2)=12 or 6⋅2=12
therefore the answer is y=-2
Answer:
90 miles
Step-by-step explanation:
There's more than one way in which to do this. I have chosen to convert '180 minutes' to '3 hours.'
Since distance = rate times time, we have here:
distance traveled in 180 minutes = (30 mph)(3 hr) = 90 miles
