Answer:

l=20m

w=5m

Step-by-step explanation:

Let "l" be the length of the rectangle &

let "w" be the width of the rectangle

l=15+w

P=2(l+w)

50m=2(15m+w+w)

50m=2(15+2w)

50m=30m+4w

20m=4w

w=5m

l=15m+w

l=15m+5m

l=20m

Proof:

P=2(l+w)

P=2(15m+w+w)

50m=2(20m+5m)

50m=40m+10m

50m=50m

Solve for x: 2 over 3 equals the quantity x minus 1 end quantity over 5
sweet-ann [11.9K]

Answer:

13 over 3

Step-by-step explanation:

Hi Jakeyriabryant! I hope you’re fine!

I hope I have understood the problem well.

If so, what the exercise raises is the following equality:

(x-1) / 5 = 2/3

From this equation you must clear the "x".

First, we pass the 5 that is dividing on the side of the x, to the other side and passes multiplying

(X – 1) / 5 = 2/3  

(X – 1) = (2/3)*5

X – 1 = 10/3

Then we pass the one that is subtracting from the side of the x, to the other side and passes adding

X  = 10/3 + 1

Remember that to add or subtract fractions they must have the same denominator or a common denominator (in this case we can write 1 as fraction 3/3). Then,

X = 10/3 + 3/3

X = 13/3

I hope I've been helpful!

Regards!

Find the coordinates if the midpoint of a line segment with endpoints (-3,4) and (7,9).
svetoff [14.1K]
Using the midpoint formula 
\frac{ x_{1}+ x_{2}  }{2},  
 \frac{ y_{1}+  y_{2}  }{2}
\frac{-3+7}{2},
 \frac{4+9}{2}
\frac{4}{2},
 \frac{13}{2}
(2,6.5)
So, your answer would be (2,6.5).

Rabbit populations can double every 30 days. If there are 26 rabbits on a farm, how many rabbits will be on the farm after 240 d
Cerrena [4.2K]

Answer:

7680 rabbits

Step-by-step explanation:

Let y represent the number of rabbits after x days and let x represent the number of days. This is an exponential growth equation in the form:

y=ab^x

Since there is an initial value of 26 rabbits on the farm and the rabbits double every 30 days, hence the equation becomes:

y=26(2^{(\frac{x}{30} )})\\\\for\ 240\ days, i.e\ x=240:\\\\y=26(2^\frac{240}{30} )\\\\y=7680\ rabbits
