Need help 1st one : 12=12 , 12= 14, x = 4 (choose )

2nd one : no solution, one solution , infinitely many solutions ( choose )

3rd one : is exactly one value, is no value, are infinitely many values ( choose )

4(2x+3)=(x) +2(3x+7)

4(2x+3)-2(3x+7)=

4-x+10=6

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
