Answer:
b=15 g=25
Step-by-step explanation:
lets translate that story problem to mathematics equations
the problem told that no. of girls are 10 more than no of boys so this will =
g=b+10
then in class there are 40 students that means
g+b=40
now we have to equations with two variables then we should substitute
(b+10)+b=40
lets remove the brackets
2b+10=40 subtract 10 from both sides
2b=30 now divide both by 2
b=15 so g=25 after you write the equation once again with the new proof or number
The third one is the correct choice because the solutions are 2 and -2
the answer would be B.
u have to simplify the first fraction by getting rid of the 4.(divide numerator and denominator by 4) and then multiply the fractions.
Hope this helps:)
Answer:
b because first u need to remove the parentheses then u disturbe
