Answer:

x = -3

Step-by-step explanation:

$\frac{2}{3} x + 7 = 5\\\frac{2}{3} x = 5 - 7\\\frac{2}{3} x = -2\\x = -2 / \frac{2}{3}\\x = -2 * \frac{3}{2}\\x = -6/2\\x = -3$

Answer:

x= -3

Step-by-step explanation:

2/3x+7=5

subtract 7 to both side (2/3x +7 -7) = 5-7

(2/3x +7 -7 = 5-7)= 2/3x= -2

then multiple by 3/2 on both sides 2/3x times 3/2 = -2 times 3/2

(2/3x times 3/2 = -2 times 3/2)= (x= -3)

3/2 times -2= -6/2 or -3

The diagram below shows a three dimensional view of the pool.

shutvik [7]

Answer:

a) $A_{f} = 408.54\,m^{2}$ , b) $A_{w} = 106.2\,m^{2}$

Step-by-step explanation:

a) The floor area of the pool is:

$A_{f} = (10\,m)\cdot (12\,m)+(18\,m)\cdot (16.03\,m)$

$A_{f} = 408.54\,m^{2}$

b) The total area of the walls of the pool is:

$A_{w} = 2\cdot (0.9\,m)\cdot (16\,m) + (0.9\,m)\cdot (16\,m) + (18\,m)\cdot (1.8\,m)+ 2\cdot (12\,cm)\cdot (0.9\,m)+(10\,m)\cdot (0.9\,m)$

$A_{w} = 106.2\,m^{2}$

Given the vectors w = <-5, 3> and z = <1, 4>, find the results of the vector subtractions. -w − z = z − w = w − z =

Elodia [21]

Answer:

Concept: Linear Algebra

Given two linearly independent vectors w and z
We want -w-z
Hence apply a negative gradient to w
w=-<-5,3> =<5,-3>
So <5,-3>-<1,4> = (<5-1>,<-3-4>)
The answer is <4,-7>

Solve this inequality 5 x + 2 < 32

Hatshy [7]

Answer:

Here is your answer:

5x + 2 < 32

solution:

5x+ 2 < 32

or, 5x < 32-2

or, 5x < 30

or, 5x < 30/2

or, 5x < 15

or, x < 15/3

or, x < 5

therefore, x < 5 ans

Hope it will help you
