Solve the simultaneous equations using elimination method.<br>4x – 3y = 1<br>x + 3y =​
babymother [125]

Answer:

x=\frac{1}{5}

y = -\frac{1}{15}

Step-by-step explanation:

4x - 3y = 1

x + 3y = 0

Req To Solve With Elimination:

Make Them Equal:

-> 4x - 3y = 1

-> 4x + 4 . 3y = 0

Simplify:

->  4x - 3y = 1

-> 4x + 12y = 0

-> 4x - 4x - 3y - 12y = 1

-> -3y - 12y = 1

-> -15y = 1

-> y = -\frac{1}{15}

-> x+3(-\frac{1}{15} )=0

-> x -\frac{1}{5}=0\\

-> x=\frac{1}{5}

A light bulb consumes 960 watt-hours per day. How many watt-hours does it consumes in 4 days and 18 hours?
MaRussiya [10]
960 watts = 24 hours

4 days = 96 hours

960 (watts) x 4 (days) = 3840 watts

12 hours= 480 watts

6 hours = 240 watts

18 hours = 720 watts

3840 (4 days) + 720 (18 hrs) = 4560
