Answer:
x=1, y=2
Step-by-step explanation:
solve by substitution so substitute x= 6y-11 in the next equation
3 (6y-11) - 2y = -1
18y -33-2y = -1
16y = 33-1
y= 32/16 =2
x= 6y -11 = 6*2 -11 = 12 -11 = 1
Answer:
d 26
Step-by-step explanation:
sin(38)=16/x
times the x on both sides
sin(38)×x=16
divide by the sin(38) on both sides
x=16/sin(38)
x=25.98=26
Answer:
x=-3
Step-by-step explanation:
Answer:
option: (a),(b),(c)
Step-by-step explanation:
- WaterSense Toilets use 1.28 gallons per flush or less while still providing equal or superior performance. This is 20 percent less water than the current federal standard of 1.6 gallons per flush.
Hence, option D is incorrect.
- it was developed with an aim of replacing an old, leaky toilet that is wasting money and water, installing a WaterSense labeled toilet is a high-performance, water-efficient option worth considering.
" The toilet float is a device that allows water to fill the tank without overflowing " .
Hence, option (a),(b) and (c) are true.
