Answer: -2

Step-by-step explanation:

convert it to a equation:

7x+8=5x+4

move x's to a side and numbers to the other

2x=-4

divide by 2

x=-2

Let us consider the number to be 'n'.

<u>Given condition</u> :

  • 7n + 8 = 5n + 4

<u>Subtract '5n' from each side</u> :

  • 7n + 8 - 5n = 5n + 4 - 5n
  • 2n + 8 = 4

<u>Subtract '8' from each side</u> :

  • 2n + 8 - 8 = 4 - 8
  • 2n = -4

<u>Divide '2' from each side</u> :

  • 2n/2 = -4/2
  • \fbox {n = -2}

∴ The number is -2.

Write the standard equation for each circle:<br> Center at (-1,6) with radius 1/3
Sunny_sXe [5.5K]
The answer is:
(X-(-1))^2 + (Y-(6))^2 = (1/3)^2

this can be simplified into the following
(X+1)^2 + (Y-6)^2 = 1/9

Jacob used 1/7 of a liter of water to fill 1/9 of the fish aquarium. How many liters of water are needed to fill the aquarium?
laila [671]
Jacob used 1/7 of a liter of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to mixed fraction
=> x  = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.

Can anyone answer this for me?
kramer

Answer:

\frac{3}{2} π (or 270°)

Step-by-step explanation:

I use the trick with the coordinates.

(0, -1)

cos270° = 0 (the x-coordinate)

sin270° = -1 (the y-coordinate)

This trick works depending on the radius.

When planning his crops, Farmer Joe knows that his 5 acres can support corn and strawberries. He wants to make $5,500 from his c
qaws [65]
This can be solved using the system of equations:

5500 = 1000c + 1500s
5 = c + s

As the first equation can have different combinations, it is the second equation that defines just how much acres or corn or strawberries(or mathematically, it defines the values of c or s in the first equation) there are. Therefore, the equation " 5 = c + s" is the constraint.
