Rearranging Equations Starter 3

Solve for y: 9t + y = 7C - 10A

• y = 7C - 10A - 9t

• y = 7C - 10A + 9t

• y = -7C + 10A - 9t

• y = (7C - 10A)/9t

Make a the subject: 11 = a/8

• a = 8/11

• a = 11/8

• a = 88

• a = 3

 $10\ g\ =\ \frac{3y}{4W}$  Solve for y.

• y = 4Wg/3

• y = 10g/4W

• y = 3/40Wg

• y = 40Wg/3 

 $\frac{p}{2y}+9P\ =\ 7A$  Solve for y

•  $y\ =\ \frac{14A-18P}{p}$  

•  $y\ =\ \frac{p}{14A-18P}$  

•  $y\ =\ \frac{p}{7A-9P}$  

•  $y\ =\ 2p\left(7A-9P\right)$  

 $\sqrt{11c+3}=2$  Solve for c.

•  $c\ =\ \frac{1}{11}$  

•  $c\ =\ \left(\frac{1}{11}\right)^2$  

•  $c\ =\ -\frac{1}{11}$  

•  $c\ =\ 11$  

r = T(c + d). Solve for c.

• $c\ =\ \frac{T}{r-Td}$

• $c\ =\ \frac{r-Td}{T}$

• $c\ =\ \frac{r}{T}-d$

• $c\ =\ \frac{T}{d}-r$

 $y^2-2=33$  Solve the equation.

•  $y\ =\ \sqrt{35}$  

•  $y\ =\ 1225$  

•  $y\ =\ \sqrt{31}$  

•  $y\ =\ 35$  

 $-r\ =\ \sqrt{-g-b}$  Make b the subject

•  $b\ =\ -r^2+g$  

•  $b\ =\ -g-r^2$  

•  $b\ =\ g+r^2$  

•  $b\ =\ g^2+r^2$  

Solve for s: 5s - 11c = 5m - 6u

• $s\ =\ \frac{5}{5m-6u+11c}$

• $s\ =\ 25m-30u+55c$

• $s\ =\ \frac{5m-6u+11c}{5}$

• $s\ =\ \frac{-5m+6u-11c}{5}$

 $-25\ +z^2=29$  Solve for z.

•  $z\ =\ \sqrt{54}$  

•  $\ z=54$  

•  $z=27$  

•  $z\ =\ 2$
