Simplify the following expression (30/45g+20)-(8/9g+7)

amid [387]

The answer is: $13-\frac{2}{9}g$

The explanation is shown below:

1- You have the following expression given in the exercise:

$(\frac{30}{45}g+20)-(\frac{8}{9}g+7)$

2- When you multiply signs, you obtain:

$\frac{30}{45}g+20-\frac{8}{9}g-7$

3. Now, you must add like terms, as following:

$-\frac{2}{9}g+13$

4. Therefore, you have that the expression simplified is:

$13-\frac{2}{9}g$

What is the solution to this system of equations (5z +y=2 ( 47 +y=5

prisoha [69]

Answer:

Z = 8.8 Y = - 42

Step-by-step explanation:

Y = 2 - 5Z

Y = 5 - 47

2 - 5Z = 5 - 47

- 5Z = - 44

5Z = 44

Z = 8.8

Y = 2 - 5 (8.8)

Y = 2 - 44

Y = - 41

Y = 5 - 47

Y = - 42

Formula
V = (1/3) pi * r^2 h

pi = 3.14
d = 3 cm. (very small)
r = d/2 = 3/2 = 1.5 cm
h = 7 cm

V= (1/3) 3.14 * 1.5^2 * 7
V = 1.04 * 1.5^2 * 7
V = 16.485 cm^3
