Answer:

17/12 or 1 and 5/12.

Step-by-step explanation:

3/4 and 2/3 needs to have the same denomenator. So, what number does both 4 and 3 go into? 12. So, 4x3=12, so we multiply the numerator by 3 too, to get 9 --> 9/12. Then, we see that 4x3=12 for 3 too so we multiply 2 by 4 which gets us 8 --> 8/12. So, now we add 9/12 + 8/12 to get 17/12, which then we make into a mixed number to get 1 and 5/12.

Let time be x distance be y

140x=y-(1)
290x=360-y-(2)

Put value in eq(2)

$\\ \rm\longmapsto 290x=360-(140y)$

$\\ \rm\longmapsto 440x=360$

$\\ \rm\longmapsto x=1.2min$

Put it in eq(1)

d=1.2(140)=168m

I need this urgently!! I need by 7:15!!

The question is telling you that the length of the rectangle is 3 metres more than twice the width.

So let:

w= width

L= length

Because the length is 3 metres more than twice the width: L= 2w+3

They also tell you the perimeter is 48 metres.

P= L+L+w+w

So the equation of the perimeter is:

48= (2w+3)+(2w+3)+2w +2w

48= 2(2w+3) + 4w

To find w, expand and simplify.

48= 4w+6+4w

48= 8w + 6

42= 8w

5.25=w

Now that you know the width, plug in the value into the length equation:

L= 2w+3

L=2(5.25)+3

L=10.50+3

L=13.5

If I am wrong let me know! I hope this helps.

To round this we have to go to the thousands place since the thousands place in this question is 8 its closer to 10 so the answer is 10k or 10,000

1/6(a+12)= -4 please help because I don’t understand this

iogann1982 [59]

Answer:

a=-36

Step-by-step explanation:

1/6(a+12)=-4

1) Distribute 1/6 to a and 12:

1/6a+2=-4

2) Subtract 2 from both sides:

1/6a=-6

3) Multiply both sides by the reciprocal of 1/6: (6/1)

a=-36

Let me know if you have any confusion on how I reached the solution :)
