Answer:
Step-by-step explanation:
Three times a number plus 8 girls would be
3x+8
The variable is x
The constant is 8
and the coefficient is 3
If Trey now has 9 times as many cards as he did when he began collecting, we can use the number of cards he had before as x.
Trey has 9x cards.
The variable in this equation is x and the constant is 9
If Nina has 3 dimes and 1 nickel in her pocket, we can say the dimes are b and the nickel is c
If she found some quarters on the ground, we can say the quarters are A, but we don't know how many, so we need x to represent how many quarters. the Variables in this equation are B, C, and A (b, c, and a)
We can write this in an equation as
3b+c +(ax) the coefficient is x, and the constant is 3
In the equation 2n+4, the variable is n, the coefficient is 4, and the constant is 2
A word problem for this equation could be:
Ray collects marbles. Ray's friend gave him 2 times as many marbles as he already had, and he found 4 marbles on the way home from his friend's house.
