Five equations are given. Each equation has infinitely many solutions, only 1 solution, or no solution at all. Select all of the equations that have only 1 solution.
A. 5a - a + 4 = 4
B. 9b - 1 = 9b
C. n-3n - 2 = -2(n + 1)
D. = -4

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

answer4 to the second power is 16

and 4 to the third power is 64,
