Answer:
16.67
Step-by-step explanation:
Step 1: We make the assumption that 20 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=20.
Step 4: In the same vein.
Step 5: This gives us a pair of simple equations
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
Step 7: Taking the inverse (or reciprocal) of both sides yields
The answer is -25
All you have to do is add -6-9 which equals -25 because “same signs add(+) and keep” “different signs subtract(-)” but “add” means positive number and “subtract” means negative number. Since they are different signs a (+) and a (-) you subtract it.
Hope this helps!
Answer:
9ab+3a
