Answer:

Step-by-step explanation:

Let she work for x hours as carpenter !
so earned money = 20x
and for blacksmith she must work for 30-x hours
so earned money = (30-x) ×25
so putting in eqn;
20x+25(30-x) = 690
so, x= 60/5 = 12
so she works for carpenter for 12 hrs and 30-12= 18 hrs for blacksmith
(3-24) / (8+4)^2
it's written like this right?
(-12) / (12)^2
do the work in the parenthesis first
(-12) / (144)
then square 12
(-1) / 12
simplify by dividing the numerator and the denominator by 12
