-Solve each equation. Example x+3=12 9+3=12
mash [69]

y + 9 = 9  | - 9 \\ y+ 9 - 9 = 9 - 9 \\ y = 0

10 + 2x = 20 | - 10 \\ 10 + 2x - 10 = 20 - 10 \\ 2x = 10 | \div 2 \\ 2x \div 2 = 10 \div 2 \\ x = 5

17 + 3c = 26 | - 17 \\ 17 + 3c - 17 = 26 - 17 \\ 3c = 9 | \div 3 \\ 3c \div 3 = 9 \div 3 \\ c = 3

x - 4 = 3 | + 4 \\ x - 4 + 4 = 3 + 4 \\  x = 7

2z - 7 = 7 | + 7 \\ 2z - 7 + 7 = 7 + 7 \\ 2z = 14 | \div 2 \\ 2z \div 2 = 14 \div 2 \\ z = 7

If a thermometer indicates 40 degrees Celsius, what is the temperature in degrees Fahrenheit?
Stells [14]
<span>So we wan't to convert the temperature from Celsius scale to fahrenheit scale. The method fot that is this: First, 0 degrees Celsius or the starting point of Celsius scale is 32 degrees Fahrenheit. And the magnitude of a degree Fahrenheit is 1.8 times greater than the magnitude of a degree Celsius, or: 1F=1.8F. So now we can construct a function that will give us temperature in degrees Fahrenheit: T(F)=1.8T(C) + 32. We have T(C)= 40, and after we put that in our function we get: T(F)= 1.8*40 + 32 = 72 + 32 = 104 F. So 40 degrees Celsius is 104 degrees Fahrenheit. </span>

Help Me!!!
Zigmanuir [339]
I'll just help quickly with a couple of expressions that are equivalent.
3(m+5+9m)
If you solve it out, you get 3m+15+27m.
Simply the expression to get 30m+15.
You can regroup to make another expression 5(6m+3) which is also equal.
