We know that the number of cakes is dependent on the time spent in baking.
We are given that Carmen can bake 84 cakes in 1.6 hours, therefore, to know the number of cakes that she can bake in 2 hours, all you have to do is cross multiplication as follows:
number of cakes = (2*84) / 1.6 = 105 cakes
Hey there! I'm happy to help!
Sum means to add. Let's call our number n.
n+15
We multiply this whole thing by 6.
6(n+15)
And this is -42.
6(n+15)=-42
We use distributive property to undo the parentheses.
6n+90=-42
We subtract 90 from both sides.
6n=-132
We divide both sides by 6.
n=-22.
Have a wonderful day! :D
