Answer:
(1) t + 15 = 5
5 - 15 = t
t = -10
(2) -4 = p - 6
-4 + 6 = p
p = 2
(3) 5/y = -2
5 ÷ -2 = y
y = -2.5
(4) 84 = 7d
84/7 = d
d = 12
(5) three times a number is less than or equal to 12
3n < 12
12/3 = n
n = 4
(6) Four less than a number is greater than negative one
4 - p > -1
4 + (-1) = p
p = 3
(7) n≤−4
i dont know what to do for this equation
(8) k >5
i dont know what to do for this equation
(9) 1/2 x = 5/6
5/6 ÷ 1/2 = x
x = 5/3
(10) 0.3a = -51
-51 ÷ 0.3 = a
a = -170
Hope this helps
