Natasha_Volkova [10]3 years ago
4 0

Answer:

D (4y-5)(3x-5)

Step-by-step explanation:

12xy -15x -20y +25

I will factor by grouping

12xy -15x      -20y +25

Factor out 3x from the first group and -5 from the second group

3x(4y-5)  -5(4y-5)

Now factor out (4y-5)

(4y-5)(3x-5)

5x-36-11x=3x+36+3x <br> What is the answer
Mariana [72]

Answer:

x = 7.2

Step-by-step explanation:

5x - 36 - 11x = 3x + 36 + 3x

add like values together:

16x - 36 = 6x + 36

add 36 to each side:

10x = 72

divide by 10 to get x alone:

x = 7.2

Step-by-step explanation:

first you convert it based on 1 in = 20 ft

8*20=160

6*20=120

now you multiply to find area

remember area is a = lw

160*120=19200

add units

19200 ft

Answer:

3.2 km/h

Step-by-step explanation:

1. Approach

The average speed is the rate at which one travels. It can be found by diving the total distance traveled over the total time it took to cover that distance. In essence, the following formula can be used to find the average speed:

\frac{total\ distance}{total\ time}=average\ speed

In this situation, one is asked to find the difference between two people's average speed. One is given the following information:

Lena: 24 miles          1.5 hours

Ras:   36km               1 hour 15 minutes

First, convert all of the numbers into the correct units (km) and (hours). Then find the average speed for each person. Finally, subtract the smaller speed from the larger speed to find the difference in the average speeds.

1. Find Lena's average speed

The problem asks one to find the average speed in the units (km/h). However, the distance Lena covered is given in (miles). Therefore, one has to multiply it by the conversion factor (1.6) in order to convert it from (miles) to (km).

24miles * 1.6 = 38.4

Now find the average speed by using the formula:

\frac{total\ distance}{total\ time}=average\ speed

Substitute,

\frac{38.4}{1.5}\\\\=25.6

2. Find Ras's average speed

Use a similar approach to work out Ras's average speed, as was used to find Lena's average speed. Since Ras's time spent is given in both hours and minutes, one must convert it to just minutes. There are (60) minutes in an hour, thus, one can rewrite the number as the following:

1\ hour \ \ 15\ minutes= 1 \frac{15}{60}\ hours = \frac{75}{60}\ hours

Now find the average speed:

\frac{total\ distance}{total\ time}=average\ speed

Substitute,

\frac{36}{\frac{75}{60}}\\\\=28.8

3. Find the difference between the speeds

Since Ras's speed is greater, subtract Lena's speed from Ras's speed.

Ras - Lena

= 28.8 - 25.6

= 3.2
