PLEASEEEE HELPPPP -1+(-5) =

valentina_108 [34]

Answer:

-6

Step-by-step explanation:

-1+(-5)

You are moving down the numberline, then subtracting again because of the negative sign. -(1+5) is how I like to think of it.

So, 1+5=6, and you add the negative sign. -1+(-5)=-6.

-5=5(d+4) Please give step by step

bekas [8.4K]

Answer:

first distribute the 5 to the d and 4
5(d+4) then becomes 5d+20
then subtract 20 from both sides of the equation
-5=5d+20 is now -25=5d
lastly divide 5 from both sides
-25=5d is now -5=d
hope this helps!
