Teacher and cookies are the common nouns.
Multiply both sides by x
75=9x
Flip the equation
9x=75
divide both sides by 9
9x/9=75/9
x=25/3
x= 8.3 or 8
so the number is 8 or you can also put 8.3
Check the answer
75/8.3= 9.03
or 75/8= 9.3
I hope that's help.
Are there answer choices?
The minimum number of people would be 45. Let's try and separate it this way :
<span>(100)
Relatives = Rel | (90) Dutch = Dut | (80) German = Ger
100 Rel –> 90 Dut = 10 Rel and 90 RelDut
80 Ger –> 10 Rel = 10 RelGer | 70 Ger -> 70 Dut = 70 GerDut
So far we have 10 RelGer, 20 RelDut and 70 GerDut and 75 Eng.
Since we are trying to get the minimum number, we have to separate it again.
10 Ger -> 10 Eng = 10 GerEng | 20 Dut -> 20 Eng = 20 DutEng
Now you have 45 Eng left that will go to 45 GerDut = 45 GerDutEng, all three heritages.</span>
