A + (-7) is the same as a - 7, so you could rewrite it as
a - 7 = -17
+ 7
a = -10
So your answer is a = -10, I hope this helps!

if a chocolate pie is divided into six equal slice and each slice has 280 colories how many colories are in the whole pie
AVprozaik [17]

Hey there!

We know that each slice has 280 calories & we also know there are 6 equal pieces, so all we have to do is multiply 280 by 6 to find how many calories the entire pie is

280 * 6 = 1,680

Therefore, the whole pie has 1,680 calories

Hope this helps you!

God bless ❤️

The sum of two numbers is 27. The larger number is 3 more than the smaller number. What are the two numbers? PLEASE DO NOT GIVE
Contact [7]
Let x and y be the two numbers

Saying "The sum of two numbers is 27" means x+y = 27. The term "sum" is the result of adding. So the first equation is x+y = 27

The second equation is y = x+3 where we assume that y is the larger number of the pair. 

So your system of equations will be
x+y = 27
y = x+3

Use substitution to solve this system. 
x+y = 27
x+( y ) = 27
x + (x+3) = 27 ... notice how y has been replaced with x+3 (since y = x+3)
x+x+3 = 27
Solve for x and then use this to find y. I'll let you finish up.

If you need more help, then please let me know.
