The first one is a. If you solve for x, equals 50. And if you retrace the steps described in a, describes the situation. Lost half, then one more.

The second is c, the inequality describes the condition and solves how many commissions he needs to earn at least 100 or more dollars a day.

42 base x +53base x = 125base x. what<br>is the value of x

Finger [1]

Answer:

Step-by-step explanation:

The largest number is 5. Therefore x ≥ 6.

Convert numbers from x system to decimal system:

$42_x=4x+2\\\\53_x=5x+3\\\\125_x=1x^2+2x+5$

Solve the equation for x:

$42_x+53_x=125_x\Rightarrow4x+2+5x+3=x^2+2x+5\qquad\text{combine like terms}\\\\(4x+5x)+(2+3)=x^2+2x+5\\\\9x+5=x^2+2x+5\qquad\text{subtract 5 from both sides}\\\\9x=x^2+2x\qquad\text{subtract}\ 9x\ \text{from both sides}\\\\0=x^2-7x\\\\x^2-7x=0\qquad\text{distributive}\\\\x(x-7)=0\iff x=0\ \vee\ x-7=0\\\\x=0$

Find the value of x? thank you

kirza4 [7]

Answer:

Step-by-step explanation:

A 5 sided shape total angles are equal to 540°

150 + 102 + 84 + x + 2x = 540

3x = 540 - 336

3x = 204

x = 68
