Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30
additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0
so x+3-3=10-3
x+0=7
x=7
Answer: There are 36 teachers total.
Step-by-step explanation:
Beacsue we know there are at least 30 teachers we need to change the fraction 3/18 becasue it is too simplified. So if we multiply the numerator and denominator by 2 we get 6/36. The new denominator is 36 which is the total amount of teachers.
The answer is y=120
First you simplify both sides of the equation then u isolate the variable.
Hey there!
12(w - 3)
= 12(10 - 3)
= 12(10) + 12(-3)
= 120 - 36
= 84
OR
12(w - 3)
= 12(10 - 3)
= 12(7)
= 84
Therefore, your answer should be:
84
Good luck on your assignment & enjoy your day!
