Question

I just need to know what do I do when it says 2t but t is 10.M - t squared 2 / (M+p) + 2t

Answer 1

Solution:

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given expression

$m-t^2\div(m+p)+2t$

STEP 2: Write the given values

$t=10,m=3,p=2$

STEP 3: Substitute the values and simplify

$\begin{gathered} 3-(10^2)\div(3+2)+2(10) \\ Follow\:the\:PEMDAS\:order\:of\:operations \end{gathered}$

We solve the bracket first:

$=3-100\div5+20$

We solve the division operator next:

$\begin{gathered} 3-(100\div5)+20 \\ 3-20+20 \end{gathered}$

We do the addition and subtraction simultaneously to have:

$3+0=3$

Hence, the result of the simplification gives 3
