Answer:

Value for X = 7

Explanation:

Given:

FE parallel to BC

Find:

Value for X

Computation:

EA / CE = FA / BF

So,

18 / 10 = (X+20) / (X+8)

18X + 144 = 10X + 200

8X = 56

X = 56/8

X = 7

Value for X = 7

An NBA game is 48 min long.If Lebron James ate a Big Mac Extra Value Meal ( that is 1360 calories) before a game, would he burn

Rasek [7]

He would lose 0.063 cal/lb during 1 minute of basketball. Lebron James weighs 249 lbs (as of now). So 1360*0.063= 85.68, which is less than his weight. (This is as much as I tried:P)

If the line joining (3x, x+1) and (11,12) has a slope of 4 what is the value of x

Irina18 [472]

Answer:

x = 3

Step-by-step explanation:

$(3x,\: x +1)=(x_1, \:y_1)$

$(11,\: 12)=(x_2, \:y_2)$

$slope = \frac{y_2 - y_1}{x_2 - x_1} \\ \\ 4 = \frac{12 - (x + 1)}{11 - 3x} \\ \\ 4 = \frac{12 - x - 1}{11 - 3x} \\ \\ 4 = \frac{11 - x}{11 - 3x} \\ \\ 4(11 - 3x) = 11 - x \\ \\ 44 - 12x = 11 - x \\ \\ 44 - 11 = 12x - x \\ \\ 33 = 11x \\ \\ x = \frac{33}{11} \\ \\ \huge \red{ \boxed{x = 3}}$

Use PEMDAS

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)
