11/1 - 11/5 Algebra 1 Raider Prep Activity

Solve:

 $\frac{3x+1}{4}=\frac{2x-1}{5}\$  

•  $x=-\frac{9}{7}\$  

•  $x=-\frac{2}{7}$  

•  $x=-\frac{8}{5}$  

•  $x=0$  

What value of x makes this equation true?

 $3x-20=-2x\$  

• -20

• -4

• 4

• 20

Solve the equation for y.

 $\frac{y-5}{2}=3x$  

•  $y=6x+10$  

•  $y=6x+5$  

•  $y=3x+5$  

•  $y=x+5$  

A formula to find the angle measure of an isosceles triangle is shown.

 $180=2x+y$  
Which equation can be used to find x?

•  $x=\frac{180-y}{2}$  

•  $x=\frac{180+y}{2}$  

•  $x=90-y$  

•  $x=90+y$  

A data set with an even number of data points is ordered from least to greatest. The middle two data points are represented by  $x_1$   and  $x_2$ . This formula can be used to find the median of the data set.

 $m=\frac{x_{1\ }+\ x_2}{2}$  
Which shows the formula solved for  $x_1$ ?

•  $x_1=m-\frac{x_2}{2}$  

•  $x_1=2m-x_2$  

•  $x_1=2m-2x_2$  

•  $x_1=m-2-x_2$

• 3 hours

• 4 hours

• 5 hours

• 8 hours
