Jose worked x hours earning $15 per hour and y hours earning $20 per hour. The total amount he earned is at least $400. Write an inequality that models this situation.

• $15y+20x=400$

• $15x+20y=400$

• $15x+20y\le400$

• $15x+20y\ge400$

 $x>4$  

Describe in words what the solution means

• A number of four or less could be a correct answer.

• A number of four or greater could be a correct answer.

• A number less than four could be correct answer.

• A number greater than four could be a correct answer.

 $10-10x=-2\left(x+7\right)$  Solve for x

•  $x=3$  

•  $x=-3$  

•  $x=-2$  

•  $x=2$  

 $wx=H$  

Solve for x

•  $x=Hw$  

•  $x=\frac{H}{w}$  

•  $x=H-w$  

•  $x=H$  

 $Y=mx+b$  

Solve for x

•  $Y-b=x$  

•  $\frac{Y+b}{m}=x$  

•  $\frac{Y-b}{m}=x$  

•  $Y-b-m=x$  

Translate the statement into an equation

The difference of two times a number(x) and three is the same as six plus three times a number(x)

• $2x-3=6+3x$

• $-2x+3=6+3$

• $-2x+3=6+3x$

• $2x-3=6x+3$

Given:
 $2x-3=6+3x$  

Is x=4 a true statement

• True

• False
