Answer: option d.
Step-by-step explanation:
If <em>y </em>varies directly as <em>x</em> and <em>z</em>, the form of the equation is:

Where<em> k</em> is the constant of variation.
If y=4 when x=6 and z=1 then substitute these values into the expression and solve for <em>k:</em>

<em> </em>Substitute the value of <em>k</em> into the expression. Then, the equation is:

To find the value of <em>y </em>when x=7 and z=4, you must substute these values into the equation. Therefore you obtain:

A ton is equivalent to 1000 pounds so:
the elephant weighs 5000 pounds
5000-570= 4430
The elephants weighs 4430 pounds more.
What midpoints are you wanting to measure?
Answer:
1-c
2-b
3-a
Step-by-step explanation:
1. 7y=14
y=2
-7y=-14
y=2
so the equation has one solution
2. 0=0
so the equation has infinite solution
3. 0=2 false
so the equation has no solution
<span>100 is not divisible by 3 when u divide 100 by 3 u get 33.333333...... not 3.33333.....
the good explanation of your answer is that 0.999999....is equal to 1
we can prove it by the following way:
let x=0.9999....
then 10x = 9.999999.....
subtract we will get 10x - x = 9.9999....- 0.99999......
which gives us 9x = 9 and therefore x =1
i hope this will help u with your confusion....... :)</span><span>
