1 multiply by 7= 7 cups of water needed
Answer:
4
Step-by-step explanation:
The diagonals are equal length:
![6x - 14 = 8x - 20\\-2x = -6\\x = 3](https://tex.z-dn.net/?f=6x%20-%2014%20%3D%208x%20-%2020%5C%5C-2x%20%3D%20-6%5C%5Cx%20%3D%203)
![BD = 6x - 14\\BD = 6 * 3 - 14\\BD = 18 - 14\\BD = 4](https://tex.z-dn.net/?f=BD%20%3D%206x%20-%2014%5C%5CBD%20%3D%206%20%2A%203%20-%2014%5C%5CBD%20%3D%2018%20-%2014%5C%5CBD%20%3D%204)
Independent: number of hours worked

Diameter of semicircle is 4 cm
so cicumference of circle is 4pi
since there are 4 semicircles, they add up to 2 circles
so total perimeter is 8pi
which when rounded off is 25.13 cm (2d. p.)
Answer:
the roots are {-4/3, 4/3}
Step-by-step explanation:
Begin the solution of 11=6|-2z| -5 by adding 5 to both sides:
11=6|-2z| -5 becomes 16 = 6|-2z|.
Dividing both sides by 12 yields
16/12 = |-z|
There are two cases here: first, that one in which z is positive and second the one in which z is negative.
If z is positive, 4/3 = -z, and so z = -4/3, and:
If z is negative, 4/3 = z
Thus the roots are {-4/3, 4/3}
