Answer:
The answer is 6x -7y = 21
Step-by-step explanation:
Im taking the diagnostic
{country albums}:{jazz albums}=2:3
3{country albums} = 2{jazz albums}
{country albums} + {jazz albums} = 45
{jazz albums} = 45 - {country albums}
3{country albums} = 2(45 - {country albums})
3{country albums} = 90 - 2{country albums}
5{country albums} = 90
{country albums} = 18

Answer:
c = √746
Step-by-step explanation:
You need to use Pythagorean Theorem (a² + b² = c²) in order to solve for the hypotenuse.
25² + 11² = c²
625 + 121 = c²
746 = c²
√746 = c
1) 2x = +/- 4 so x = +/- 2
2) x-3 = 7 OR x - 3 = -7
so x = 10 or x = -4
3)2x + 5 = 21 OR 2x + 5 = -21
so x = 8 or x = -13
4) x + 4 = 6 OR x + 4 = -6
so x = 2 or x = -10
5) x + 2 = -(2x+4) OR x + 2 = 2x + 4
x = -2 or x = -6
6) x + 7 = 0
x = -7
7) you forgot the equal sign somewhere in this problem
