Answer:
8:55
Step-by-step explanation:
7:30 plus 1 hour is 8:30. Quarter is 25 or 1/4. Then you add 8:30 plus 25 which gives you 8:55.
1/5(10x−15)=1/4(12x−8)
1/5(10x−15)=1/4(12x−8)
Simplify:
(1/5)(10x)+(15)(−15)=(1/4)(12x)+(1/4)(−8)(Distribute)
2x+−3=3x+−2
2x−3=3x−2
Subtract 3x from both sides.
2x−3−3x=3x−2−3x
−x−3=−2
Add 3 to both sides.
−x−3+3=−2+3
−x=1
Divide both sides by -1.
−x/−1 = 1/−1
x=−1
SA=2LW+2WH+2HL
SA=2(8*3)+2(3*5)+2(5*8)
SA=158 cm
5x - 20y = 60...reduce by dividing by 5
x - 4y = 12
this is the same as the other equation....therefore, it is the same line...meaning infinite solutions
=============
y - 7x = -14
y = 7x - 14.....slope = 7, y int = -14
7y - 49x = -2
7y = 49x - 2
y = 7x - 2/7.....slope is 7, y int is -2/7
if the slopes are the same, but the y int are different, then u have a parallel lines with no solutions
