Solve for x 3x + 3 − x + (−7) > 6 A. x > (−5) B. x > 2.5 C. x > 5 D. x < 5
denpristay [2]

ANSWER

C. x>5

EXPLANATION

The given inequality is:

3x + 3 − x + (−7) > 6

Deal with the parenthesis first to obtain;

3x + 3 − x −7 > 6

Group similar terms to get:

3x − x> 6-3+7

Combine similar terms to get,

2x \:  > \:  10

Divide both sides by 2 to obtain:

x \:  >  \: 5

The correct choice is C. x>5

KengaRu [80]

Answer:

5 cm

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

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

Here l = 20, h = 12, V = 1200 and b is to be found, thus

20 × b × 12 = 1200, that is

240b = 1200 ( divide both sides by 240 )

b = 5
