7n+5=5n+25 subtract 5n from both sides
2n+5=25 subtract 5 from both sides
2n=20 divide both sides by 2
n=10
Answer:
D
Step-by-step explanation:
7 is it because it is positive
Answer:
Part A: 1 & 225, A number times itself equals a perfect Square.
Part B: No, 289 is NOT perfect square.
Step-by-step explanation:
Part A: 1*1=1, 15*15=225 (Perfect Squares)
Part B: Utilizing the Factor Rainbow one can see that the same number does not exist on both sides of the rainbow simultaneously.
Step-by-step explanation:
4y = 3x +8
y= 3/4x +2
3y = 4x -6
y = 4/3x -2
neither, perpendicular is negative reciprocal, and parallel m is the same. 3/4 =\ 4/3 and they are not negative reciprocals.
To solve for x first move all the x to one side and the numbers to the other side.
-2x+3=-4/9x-1
Add 1 to both sides
-2x+4=-4/9x
Add -2x to both sides
4=-4/9x+2x
Get common denominators to combine the x
4=-4/9x+18/9x
4=14/9x
Multiply by 9 and divide by 14 to both sides.
4*9/14=x
36/14=x 18/7=x
