Answer:
The numbers are 56, 280 and 156
Step-by-step explanation:
Let
x -----> the first number
y ----> the second number
z ----> the third number
we know that
y=5x -----> equation A
z=x+100 ----> equation B
x+y+z=492 ----> equation C
Solve the system of equations by substitution
substitute equation B and equation A in equation C and solve for x
x+5x+x+100=492
7x=492-100
7x=392
x=56
<u><em>Find the value of y</em></u>
y=5x -----> y=5(56)=280
<u><em>Find the value of z</em></u>
z=x+100 ----> z=56+100=156
therefore
The numbers are 56, 280 and 156

also know as helping one side of the ecologic standards in nature without getting anything in return. vines cling to trees to get something to hold onto to, and to absorb some energy from the tree without actually killing it. this is another way to think about it because the tree gets absolutely nothing from the vines. </span>
Answer: 17/14
Explanation:
(-13-4)/2-3[-{(-3) x (-7)-(3+5)}]
= -17/2-3[-{21 - 3 - 5}]
= -17/2-3[-13]
= -17/2-3-13
= -17/-14
= 17/14
