Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x.

364 = 1.40x

Solving for x gives x = 260.

Thus, the autograph of the basketball player was worth only $260 last year.

Answer:

x = 38°

Step-by-step explanation:

Complementary angles = 90°

90° = x + x+14

90° = 2x + 14

104 = 2x

x = 52°

the next angle should be 52 - 14 = 38°

So x = 38°

3/4 (x +21) = 10 1/2<br> What does x equal?

Elena L [17]

Answer:

$\huge \boxed{ \boxed{ \red{x = - 7}}}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

$\sf distribute : \\ \frac{3 x+ 63}{4} = 10\frac{1}{2}$
$\sf simplify \: mixed \: fraction : \\ \frac{3x + 63}{4} = \frac{21}{2}$
$\sf cross \: multipication : \\ 2(3x + 63) = 84$
$\sf distribute \: 2 : \\ 6x + 126 = 84$
$\sf cancel \: 126 \: from \: both \: sides : \\ 6x + 126 - 126 = 84 - 126 \\ 6x = - 42$
$\sf divide \: both \: sides \: by \: 6 : \\ \frac{6x}{6} = \frac{ - 42}{6} \\ \bcancel{\frac{6x}{6} } = \frac{ \cancel{ - 42} \: ^{ - 7} }{ \cancel{ \: 6}} \\ \therefore \: x = - 7$
