Answer: D The upward tension force in the cable is equal to the downward force of gravity.
Step-by-step explanation:
X+0=18
2x+y=19
(-2)x+(-2)0=(-2)18
2x+y=19
0+y= -17
2x+ (-17)=19
2x=36
y=-17
x=18
If you would like to simplify the following expression <span>(28x - 7y) + (32x + 52y), you can do this using the following steps:
</span>(28x - 7y) + (32x + 52y) = <span>28x - 7y + 32x + 52y = 28x + 32x - 7y + 52y = 60x + 45y
</span>
The correct result would be B. <span>60x + 45y.</span>
Answer:
Total eclipse was 
minutes longer than in 2005.
Step-by-step explanation:
It is given in the question that total eclipse in 2003 lasted 
minutes and in 2005 it lasted 3/8 of a minute.
We have to calculate how much longer did it last in 2003.
So we have to subtract the duration in 2003 by duration in 2005
Total time taken in 2003- total time taken in 2005
minutes
(x+5)*7=133
7x+35=133
7x=98
x=98/7
x=14
