Based on the answer choices, we suspect you intend
.. (x -1) +26 = -4x
This simplifies to
.. x +25 = -4x
.. 25 = -5x . . . . . subtract x
.. -5 = x . . . . . . . divide by the coefficient of x
Selection D appears to be appropriate for the question we think you asked.
Let log5 125 = x
Removing log you get 5^x = 125
Rewrite 125 as 5^3
Now 5^x = 5^3
x = 3
Answer:
176 reams in 11 cases
Step-by-step explanation:
1 = 16
1 x 11 = 11
16 x 11 = 176
Supplementary means that the angles have to add up to 180, so you have your equation.
180=5x+17x-18
198=22x
x=9
Then to find the measures of the angles, you plug x back in.
m∠ABD=5(9)=45 degrees
m∠BDE=17(9)-18=153-18=135 degrees
