The number of girls in a school is 57 less than 2 times the number of boys in the school there are 143 girls in this school how many boys are in the school

-43

Step-by-step explanation:

143 equal number of girls. The boys is unknown so they'll be x and the question says 2 times.So the equation would be 143=57-2x.

143=57-2x

so subtract 57 from both sides (57 and 143).

86=-2x

divide each side by -2

so x= - 43

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

14.29%
