Answer:
f = -11.25
Step-by-step explanation:
-9f = 90 - f
-8f = 90
f = 90 / -8
f = -11.25
The additive inverse of a number is that number with its sign changed.
The additive inverse of 5/8 is -5/8, so that is the value of <em>m</em>.
The sum of a number and its additive inverse is <em>zero</em>. (This is actually the definition of <em>additive inverse</em>.)
5/8 is found at 5/8 on the number line.
m is found at -5/8 on the number line.
"sum" is found at 0 on the number line.
Only one time...............
Marco spent more than $23. M > 23
We know the Kareem spent 8 less than Marco and that Kareem spent more than 15. If we add 8 onto the 15, we know that Marco has to be more than 23.
To graph this, draw an open circle at 23 and have an arrow going to the right.
