Answer:
x=-
Step-by-step explanation:
subtract -3(2x-1)+8=15
-8 -8
_____________
-3(2x-1)=7
divide
then simplify
2x-1=
add both sides
2x-1+1=+1
simplify again
2x-1+1=+1=2x=
divide by 2
2x=
-2 -2
_________
2x÷2=1
x=-
The cut-off point is 0.5: higher than this would be closer to 1, and lower would be closer to 0
and 3/8 is lower than 0.5: we know this because a bigger number, 4/8 is equal to 0.5
so it's closer to 0!
Answer:
x = -3/8
Step-by-step explanation:
4(3-2x)=15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 = 15-12
-8x =3
Divide each side by -8
-8x/-8 = 3/-8
x = -3/8
Answer: 1,278
Step-by-step explanation: 2(18x18)+2 1/2(18x14)
p.e.m.d.a.s. 18x18= 324 18x14= 252
2x324= 648 2.5x252=630
648+630 =1,278
<em>1452 feet</em>
- Step-by-step explanation:
<em>1 hour = 60min×60sec = 3600 sec</em>
<em>1 miles = 5280 feet</em>
<em>22 miles = 22×5280ft = 116160 ft</em>
<em />
<em>3600sec ................. 116160 ft</em>
<em>45sec ................................ x ft</em>
<em>x = 45×116160/3600</em>
<em>= 5227200/3600</em>
<em>= 1452 feet</em>
