Answer: x = -1
Step-by-step explanation:
Starting:
x-5(x+1)=3x+2
Simplify the left side:
-4x-5=3x+2
Move all the terms with an x to the left:
-7x-5=2
Move all the terms without an x to the right:
-7x=7
Divide both sides by -7:
x = -1
Answer:
Option D. 7/250 = 24.8/x; 885.71
Step-by-step explanation:
we know that
Using proportion

let's common be "x" 8x add 5x equal to 13 x now x equal to 26 devise 13 equal to 2,. so ans is 2
-2[9 - (x + 7)]
-2[9 - x - 7]
-2[-x + 9 - 7]
-2[-x + 2]
-2[-x] - 2[2]
2x - 4
The answer is C.
Square root (5-2)^2 +(4+3)^2
Square root of 3^2 +7^2
Square root of 9+49
Square root of 58
