Alex_Xolod [135]
<span>7n + 4 - 5n <= 2(n+2) Let's simplify these expression first 2n + 4 <= 2(n + 2) 2(n +4) = 2n + 4 The LHS and RHS expressions are the same but the inequality says contrary Hence 2n + 4 is not less than but equal to 2(n + 2). 7+ 6a >= -4(2-a) - 2a -4(2-a) - 2a = -8 + 4a - 2a = -8 + 2a. It should be obvious that 7 +6a is greater than the RHS expression. Suppose a= 2 then we have 7 + 6(2) = 19 while -8 + 2(2) = - 8 + 4 = -4 So it follows that 7 + 6a >= -4(2-4) -2a 4x >= 8. The expression is always true so the equal to option is out.</span>

Answer:

30

Step-by-step explanation:

We require to calculate the volume of 1 brick

V = lbh ( l is length, b is breadth and h is height ), that is

V = 14 × 8 × 5 = 560 cm³

Now divide the volume of concrete available by the volume of 1 brick.

number of bricks made = \frac{16800}{560} = 30

Simplify, THEN evaluate for x = 3, y = -4, and z= -2.<br> 7(x - y) - 3(2 + 2x)
Tamiku [17]

Answer:  25

<u>Step-by-step explanation:</u>

   7(x - y) - 3(2 + 2x)

= 7x - 7y  - 6  - 6x

=   x - 7y  - 6

for x = 3, y = -4

      3 - 7(-4) - 6

=     3 + 28  - 6

=         31     - 6

=             25
