Answer:

9.6 km

Step-by-step explanation:

The last third of the trip is 3200 meters. The first two thirds can be calculated by multiplying that value with two:

d_{1}=3200*2\\d_{1}=6400m

The total distance is the sum of the two thirds and the last third of the trip:

d_{1} +d_{2}\\=6400+3200\\=9600m

To convert the distance to kilometres, the value should be divided by 1000:

\frac{9600}{1000}=9.6km

Three sides of a quadrilateral are the same length, g, The length of the fourth side is 7 inches,
Ulleksa [173]

Answer:

Step-by-step explanation:

Let s represent the length of each of the three sides mentioned.  The length of the fourth side is 7 inches.  Adding the lengths of the four sides together yields 10 inches:  g + g + g + 7 = 10 (inches)

Then 3g + 7 = 10, or 3g = 3, or g = 1.  

This equation is OK, but there's no solution, since 3g or just 3 is less than 7.  With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.

Prove algebraically that each expression has the same value by evaluating each expression for y=5:
Illusion [34]

Answer:

See explanation

Step-by-step explanation:

Given two expressions

7(3y-5)-2(10+4y)

and

13y-55

Substitute y = 5 into each expression:

1.

7(3y-5)-2(10+4y)\\ \\=7(3\cdot 5-5)-2(10+4\cdot 5)\\ \\=7\cdot (15-5)-2\cdot (10+20)\\ \\=7\cdot 10-2\cdot 30\\ \\=70-60\\ \\=10

2.

13y-55\\ \\=13\cdot 5-55\\ \\=65-55\\ \\=10

As you can see the results are the same.
