Answer:
X=2
Step-by-step explanation:
20x+40=80
20x+40-(80)=0
20x-40=0 20x=40
x=40/20
X=2
Answer: X=8
Since it has a right angle and you have 2 sides.
Answer:
31,536,000s on a 365 day year
31,622,400s on a leap year
There are 86,400 seconds in one day; multiply that by the number of days.
seconds per day x number of days
Answer:
-5(3x+4) = 25
-15x-20=25
-15x=25+20
-15x=45
>then divide both side by -15
Therefore: X=-3
4(x+2)-3(2x-4)=10
4x+8-6x+12=10
-2x+20=10
-2x=-10
> divide both sides by -2
Therefore: x= 5
Answer:
C.) -1/2
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes.
- Opposite = opposite signs (+ & -)
- Reciprocal = flipped positions in fractions (1/2 ⇒ 2/1)
Therefore, the slope of a line perpendicular to the line y = 2x - 3 must be -1/2.
