Answer:
x = 4
Step-by-step explanation:
3 x ( 4x -7 ) = 27
3 x 4x = 12x
3 x -7 = -21
12x -21 = 27
12x -21 + 21 = 27 + 21
12x = 48
12x/12 = 48/12
x = 4
Answer:
A = 176.63 cm²
Step-by-step explanation:
Area of circle = π r ²
A = (3.14)(7.5)²
A = (3.14)(56.25)
A = 176.63 cm²
Answer:
x = 1
Step-by-step explanation:
Given
12x + 3 = 15x ( subtract 12x from both sides )
3 = 3x ( divide both sides by 3 )
1 = x
Answer: M =
Step-by-step explanation:
M (x + y) + 4y = x + 2y (Multiply in both sides)
M (x + y) = x + 2y - 4y
M (x + y) = x - 2y (Divide (x+y) from both sides)
M =
