Answer:

Step-by-step explanation:

Since the 2 legs are congruent, then

3x + 12 = 33 ( subtract 12 from both sides )

3x = 21 ( divide both sides by 3 )

x = 7

1.3n-0.03=-9 (solve for n) grade lvl. 7
bazaltina [42]

Hello from MrBillDoesMath!

Answer:

-6.9


Discussion:  

1.3n - 0.03 = -9     =>              multiply both sides by 100

130n - 3 = -900 =>

130n = -900 +3 =  -897 =>     add 3 to both sides

n = -897/130  =>

n =  - (69 * 13)/ (10*13) =>

n = - 69/10 = - 6.9




Thank you,

MrB
