Answer:

x=1.875   y=-0.875

Step-by-step explanation:

10x-3y=3                     10x-3y=3

3(2x+y)=(9)3                +<u>6x+3y=27</u>

                               1/16(16x)=(30)1/16  = x=1.875

   10x-3y=3                  10x-3y=3

 -5(2x+y)=(9)-5           -<u>10x-5y=4  </u>                        

                                    1/-8(-8y)=(7)1/-8 = y=-0.875

Lera25 [3.4K]

Answer:

$39.90

Step-by-step explanation:

if each video game cost $3.30, and she rented 7, then you multiply $3.30 by 7, to get $21.10, and if each DVD was $4.20, and she rented 4, then its $4.20x4= $16.80

after that you just add the two total costs together, which is $23.10+$16.80=$39.90

The equation for a circle with center (h, k) is (x - h)^2 + (y - k)^2 = r^2. If a circle is modeled by the equation x^2 + (y + 6
Ronch [10]

(x - h)^2 + (y - k)^2 = r^2

x^2 + (y + 6)^2 = 100

we can rewrite this as

(x-0)^2 + (y - -6)^2 = 10^2

the center is (0,-6) and the radius is 10

3*x+36=96 i give crown if you help me out
pychu [463]

Answer: x = 20

Step-by-step explanation:

Hey there! If you have any questions feel free to let me know in the comments below.

Step 1: <u>Subtract 36 from both sides.</u>

3x = 96 - 36

Step 2: <u>Simplify 96 - 36  to  60.</u>

3x = 60

Step 3: <u>Divide both sides by 3.</u>

x = 60/3

Step 4: <u>Simplify 60/3 to 20.</u>

x = 20
