Answer:

5 meters long and 3 meters wide.

Step-by-step explanation:

The length is 2 meters more than the width.
So, 2+w = the length
So, 2(2+w) + 2w = 16
Then you solve for (w).
w = 3
Since the length is 2 more than the width (l) is 3+2
The length is 5

Answer:

Length: 5

Width: 3

Step-by-step explanation:

l=2+w

2w+2l=16

2w+2(2+w)=16

2w+4+2w=16

4w+4=16

4w=12

w=3

l=2+3

L=5

Jane is standing at the base of a 6300ft tall mountain. If she climbs 15% of the remaining height each day, how many feet will s
Andrews [41]

Answer:

Total ft climbed= 3,011.36

Step-by-step explanation:

<u>Giving the following information:</u>

Total ft= 6,300

Climbing rate= 15% of the remaining height per day

<u>Total ft climbed per day:</u>

Day 1= 6,300*0.15= 945

Day 2= (6,300 - 945)*0.15= 803.25

Day 3= (5,355 - 803.25)*0.15= 682.76

Day 4= (4,551.75 - 682.76)*0.15= 580.35

Total ft climbed= 3,011.36

If the perimeters of each shape are equal, which equation can be used to find the value of x? A triangle with base x + 2, height
Tju [1.3M]

Correct question :

If the perimeters of each shape are equal, which equation can be used to find the value of x? A triangle with base x + 2, height x, and side length x + 4. A rectangle with length of x + 3 and width of one-half x. (x + 4) + x + (x + 2) = one-half x + (x + 3) (x + 2) + x + (x + 4) = 2 (one-half x) + 2 (x + 3) 2 (x) + 2 (x + 2) = 2 (one-half x) + 2 (x + 3) x + (x + 2) + (x + 4) = 2 (x + 3 and one-half)

Answer: (x + 2) + x + (x + 4) = 2 (one-half x) + 2 (x + 3)

Step-by-step explanation:

Given the following :

A triangle with base x + 2, height x, and side length x + 4 - - - -

b = x + 2 ; a = x ; c = x + 4

Perimeter (P) of a triangle :

P = a + b + c

P =( x + 2) + x + (x + 4) - - - (1)

A rectangle with length of x + 3 and width of one-half x

l = x + 3 ; w = 1/2 x

Perimeter of a rectangle (P) = 2(l+w)

P = 2(x+3) + 2(1/2x)

If perimeter of each same are the same ; then;

(1) = (2)

(x + 2) + x + (x + 4) = 2(x+3) + 2(1/2x)

Find the value of t needed to make the equation shown true. <br><br> 25t = 12.5
-Dominant- [34]

Answer:

1/2

Step-by-step explanation:

Hi Avahosel2020!

To find the value of t we need to simplify the equation:

25t = 12.5

To just get t, we must divide 25 on both sides:

\frac{25t}{25} = \frac{12.5}{25}

<u>We can move the decimal one spot over and add a 0 to the denominator:</u>

\frac{25t}{25} = \frac{125}{250}

t = \frac{125}{250}

Simplifying!

\frac{125}{250} = \frac{1}{2}.

Thus, t has the value of $\boxed{\frac{1}{2} }$.
