Answer: 60 students
Step-by-step explanation:
So, in the first situation 430 students were surveyed and 258 said that their favourite pet was a dog. The second situation is 100 students and x said that their favourite pet was a dog. We are solving x.
430=258
100= x
Cross multiply
So that is
430 x X= 100x258
430x=25800
Divide both sides by 430
Answer: 60 students
Answer:
x=155
Step-by-step explanation:
(2x-120)+10=180
or,2x-130=180
or,2x=180+130
or,2x=310
or,x=310÷2
x=155
