Answer:x=30
Step-by-step explanation:
So first you have to find x so add all your sides together:
Equation: 45+2x+0.5x+x=150
Combine like terms: 45+3.5x=150
Subtract 45 from -45 -45
both sides: 3.5x=105
Then divide by 3.5: x=30
Now that you have your x substitute it in:
2(30)=60
0.5(30)=15
and the last one is x=30
And there you have all your sides! If you wanna check it just add up all the sides and it should equal 150.
Answer:
D
Step-by-step explanation:
None of them logically make sense. A is wrong because it is a higher amount of people who carry a cell phone than not. B and C is wrong because not 100% of people they interviewed carry a cell phone so D is the correct answer
Actually, DIEDERICK drove faster than BROOK. What you can do to find out the answer, is divide. Brook drove 180 miles in 3 hours, so divide 180 by 3, and you get 60. If you divide 160 by 4, you get 40. So, that means that Diederick drove faster than Brook.
