Answer:

(-1 , 5/2)

Step-by-step explanation:

2x²-3x=5

2x²-3x-5=0

2x²+2x-5x-5*1=0

2x(x+1)-5(x+1)=0

(x+1)(2x-5)=0

x+1=0 ;2x-5=0

x=-1 ; 2x=5

x= -1 ; x=5/2

Answer:

The answer is -33.

Step-by-step explanation:

To solve the given equation we will follow the PEDMAS rule.

PEDMAS stands for :

$\purple\star$ P = Parentheses
$\purple\star$ E = Exponents
$\purple\star$ M = Multiplication
$\purple\star$ D = Division
$\purple\star$ A = Addition
$\purple\star$ S = Subtraction

Solving the question by PEDMAS rule :

$\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 - \Big( - 27 - 31\Big) + 40\bigg\}}}}\end{gathered}$

$\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 - \Big( - 58\Big) + 40\bigg\}}}}\end{gathered}$

$\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 + 58 + 40\bigg\}}}}\end{gathered}$

$\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 + 98\bigg\}}}}\end{gathered}$

$\begin{gathered}{\implies{\sf{29 - \Big\{ \: 62 \: \Big\}}}}\end{gathered}$

$\begin{gathered}{\implies{\sf{29 - 62}}}\end{gathered}$

$\begin{gathered}{\implies{\sf{ - 33}}}\end{gathered}$

$\begin{gathered} \star{\underline{\boxed{\sf{\red{ - 33}}}}}\end{gathered}$

Hence, the answer is -33.

I need help I tried to do this question with one C and with two C

OverLord2011 [107]

There are two c's. You must pay attention to capitalization, there's a lowercase c and an uppercase C which represent two different variables. Also, the W is capitalized which could make your answer incorrect if you don't use the same notation.

Solving for small c..

$C = \frac{Wtc}{1,000} \\\\ 1,000C = Wtc \\\\\frac{1,000C}{Wt}= c$

So it's the answer shown in the picture, but it should be a capital W instead of a lowercase w.
