Simplify the expression: show all ur steps/ wrk PLEASE,1+2x3-18/3+(5(2+2)]
Maurinko [17]
Ok let's do this*pops knuckles*



let's add the first side

1 + 2 \times 3 - 18
order of operations demands that we do multiplication first(P.E.M.D.A.S)

so
2 \times 3 = 6
now we can add the 1 from
1 + (6) - 18
into our six


6 + 1 = 7
now we substract

(7) - 18 =  - 11
now we have
- 11  \div 3 + (5(2 + 2))
now we focus on the
other side
3 + (5(2 + 2))
since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.
(5(2 + 2)) = (((5 \times 2) + (5 \times 2) = 20
now we have
3  + 20 = 23

(the three is from the original equation)

now we plug in our final numbers

- 11 \div 23
or
\frac{ - 11}{23}
I hope this helps

zzz [600]

Answer:

Numerical expression 1

\frac{4}{10000} * \frac{5}{1000}  = \frac{20}{10000000} = \frac{1}{500000}

Numerical expression 2

\frac{1}{50000} = 0.2 * 10^{-4} = 2 * 10^{-5}

Numerical expression 3

1 : 50000

Step-by-step explanation:

Numerical expression 1

\frac{4}{10000} * \frac{5}{1000}  = \frac{20}{10000000} = \frac{1}{500000}

Numerical expression 2

\frac{1}{50000} = 0.2 * 10^{-4} = 2 * 10^{-5}

Numerical expression 3

1 : 50000
