Mathematics
1 answer:
I am Lyosha [343]3 years ago
6 0

Answer:

2x + y = 12 & x = 9 - 2y --- (x = 5, y = 2)

x + 3y = 16 & 2x - y = 11 --- (x = 7, y = 3)

y = 11 - 2x & 4x - 3y = -13 --- (x = 2, y = 7)

2x + y = 11 & x - 2y = -7 --- (x = 3, y = 5)

What is the perimeter, P, of a rectangle that has a length of x + 6 and a width of y - 1?
Mekhanik [1.2K]

Answer: P = 2x + 2y + 10

Step-by-step explanation: The perimeter (P) of a rectangle is given as

P = 2L + 2W

By factorizing the right hand side of the equation we now have

P = 2(L + W)

However, the length of the rectangle is given as x + 6 and the width is given as y - 1

If P = 2(L + W), then

P = 2(x + 6 + {y - 1} )

P = 2(x + 6 + y -1)

P = 2(x + y + 5)

After expanding the bracket, we now have

P = 2x + 2y + 10

How would you estimate whether 27/50 is closer to 1/2 or 1 without using a number line? Explain.
Ivahew [28]

Answer

Find\ out\ the\ how\ would\ you\ estimate\ whether\ \frac{27}{50}\ is\ closer\ \frac{1}{2}  to\ or 1\ without\ using\ a\ number\ line .

To prove

As\ the\ value\ of\ \frac{27}{50}\ in\ decimal\ form.

= \frac{27}{50}

= 0.54

As\ the\ value\ of\ \frac{1}{2}\ in\ decimal\ form.

= \frac{1}{2}

= 0.5

As\ the\ value\ of\ 1 \ in\ decimal\ form.

= 1.00

Now we find out the mid point of the 0.5 and 1.00 .

Mid\ point = \frac{1.00+0.5}{2}

(Mid point is the point lies middle of a line segment .)

Mid point = 0.75

Thus

0.54< 0.75

This shows o.54 lies between 0.5 and 1.00

This means 0.54 lies right to 0.5 and left from 1.00 .

Therefore

\frac{27}{50}\ lies\ right\ to\ \frac{1}{2} and\ left\ from\ 1.
