8x-5y=21 simultaneous linear equation<br>2x+9y=-5
olya-2409 [2.1K]

Answer:

x=2 and y=-1

Step-by-step explanation:

If two equations are given, we can solve one of the equation in terms of single variable and put it in the other equation which will further give the value of x and y.

For the given equations:

8x-5y=21              Equation:1

2x+9y=-5             Equation:2

Solving equation multiply equation 2 with 4 on both the sides

8x+36y=-20        Equation 3

Subtracting Equation:3 from Equation:1

8x-5y-(8x+36y)=21-(-20)\\8x-5y-8x-36y=21+20\\-41y=41\\y=-1

Putting value of 'y' in Equation:2 which will give the value of x

2x+9y=-5\\2x+9(-1)=-5\\2x-9=-5\\2x=4\\x=2

Denise gets 450 minutes each month to use on her cell phone. Last month, she used 360 minutes. What percent of her minutes did s
guajiro [1.7K]

Answer:

80%

Step-by-step explanation:

Denise used 360 minutes out of 450 minutes. You would set this up as a fraction. Then, you would have to find out the percentage of how much Denise used. You would put 360/450 across from x/100. You find the value of x by multiplying 360*100 which equals 36000. You then would divide it by 450 to get a product of 80. This is how you would get 80%.
