Let the unknown number be x.
x × -7 = 7 (x + -40)
-7x = 7x - 280
-14x = -280
x = 280/14
x = 20
Hope this helps!
The formula for volume is length times width times height so it would be 18×18×6 so your answer should be 1,944

Step-by-step explanation:
Answer:
-4e - 9
Step-by-step explanation:
This requires combining like terms, which means that you combine the same types of values. In this one there are two "types" of values: something that involves the variable e and just normal numbers. Let's say that the "e"s are oranges and the regular numbers are apples. Remember, you can't simply add oranges and apples together
let's start with apples (the regular numbers)
you have -19 (just pretend the minus sign is attached to the value following)
and +10
so -19+10 is -9
we have -9 apples
so now let's look at oranges, represented by e
you have 3e and -7e
if one e is one orange, then you could say that there are 3 oranges and -7 oranges
so if you subtract you get -4e, or -4 oranges
now let's add that back together with the apples, remembering that you can't actually combine them
so it would be -4e - 9
(-4 oranges and -9 apples)
Hey there!
These are the factors of 12:
1, 2, 3, 4, 6, 12
These are the factors that add up to 7:
6+1
3+4
These are the factors of 12 that add up to 7 and multiply to 12:
3 & 4
Hope everything is clear.
