You use the distributive property to simplify expressions.

4x+3(2x+1)

2 times 2x is 6x
3 times 1 is 3
4x times 2x is 8x
4x times 1 is 4x

total that is 6x+8x+4x+3=18x+3

Hope it helps!

The number of males in the classroom is three more than twice the number of females. Of the total number of students is 57, how
dolphi86 [110]

Answer:

Step-by-step explanation:

Given that the number of males in the classroom is three more than twice the number of females.

the total number of students is 57

Let x be the no of males then no of females = 57-x

Also we have 3 more than twice no of females as

2(57-x)+3

This equals x

2(57-x)+3=x\\114-2x+3=x\\3x=117\\x=39

No of males = 39, no of females = 18
