Solve the inequality for x 12x>9(2x-3)-15

Mathematics
1 answer:
algol [13]2 years ago
8 0

Step-by-step explanation:

12x > 9(2x - 3) - 15

12x > 18x - 27 - 15

12x > 18x - 42

42 > 6x

7 > x

so, this is true for all values < 7

so, x is in (-infinity, 7)

both ends but included - therefore the round brackets.

What percent is 608 million of 845 million
wlad13 [49]
Hello,

To find the percentage, simply divide the smaller number to the larger number. In this situation, we divide 608 million by 845 million, which will get you:
0.719526627219. At this point, move the decimal place 2 places to the right to get the percent form of the decimal. Let's also round this decimal up.

After you move the decimal place, it's now 71.9526627219, and if we round it to the nearest 10th, it would be 71.95%.

In conclusion, the percent is 71.95%.

Hope this helps!

Help me find the area of the question c please
Marysya12 [62]

Answer:

16

Step-by-step explanation:

Shape C is A trapezoid

Area of trapezoid = \frac{a+b}{2} h

where a and b =  base lengths and h = height

The trapezoid has the following dimensions

base 1 = 3 units

base 2 = 5 units

height = 4 units

Using these dimensions we plug in the values into the formula stated above.

A=\frac{3+5}{2} 4\\3+5=8\\\frac{8}{2} =4\\4*4=16

Hence the area of shape C = 16 square units

Afina-wow [57]

Answer:

Step-by-step explanation:

salut :

en utilisant le theorem de Pythagore on obtient :

AC²= AB² + BC²

(a+5)² = 7²+a²

a²+10a+25 = 49+a²

10a+25 =49

10a =24

donc : a = 24/10 = 12/5 = 2.4 unit
