Trust Me! Good Luck Lovelys! :D
Ps. No matter what day you see this you can ask me any questions about that lesson if you don't just want the answers and I will help you through it until you understand!
This was no help! I have a whole writing to write and need help on this.

Thank You
dont think your answers are right
1) To compute -5g-6 for g = -2, substitute -2 for g in the expression.
(-5 * -2) - 6 = 10 - 6 = 4
2) The algebraic expression for the sum of 3 Coins and c Coins would be:
3 + c
3) To find the value of x that is a solution to the equation x-2 = 16, isolate x by adding 2 to both sides of the equation.
x - 2 + 2 = 16 + 2
x = 18
4) To solve the equation using mental math, multiply both sides of the equation z / -12 = -5 by -12 to eliminate the fraction.
z = -5 * -12
z = 60
5) To estimate the solution of the equation x-8.1 = 5.3 to the nearest whole number, round the numbers to the nearest whole number first:
x - 8 = 5
x = 5 + 8
x = 13
6) To solve the equation 14 = t-44, isolate t by adding 44 to both sides of the equation.
14 + 44 = t - 44 + 44
58 = t
7) To solve the equation -30 = j + 50, isolate j by subtracting 50 from both sides of the equation.
-30 - 50 = j + 50 - 50
-80 = j
8) To solve the equation 2.8x = -9.24, divide both sides of the equation by 2.8 to isolate x.
x = -9.24 / 2.8
x = -3.3
9) To solve the equation 5.8 = z / 2.2, multiply both sides of the equation by 2.2 to isolate z.
5.8 * 2.2 = z
z = 12.76
for example number 9:
(2.2)(5.8) = (2.2)(z/2.2)
so
(2.2)(5.8) = z
Clearly I already know how to do these. You are supposed to learn how. Please try to do them so I can figure out what you are missing.
