Find the common denominator for 3 and 10 which is 30 now the denominator is 30 and what you do with one side you do to the other so 6 7/10 turns into
6 21/30 and 2 1/3 turns into 2 10/30 now subtract them so 6 21/30-2 10/30=
4 11/30
Answer:
11°<x°<58°
Step-by-step explanation:
first find out how much x can be by using 180 degrees.
(5x+3)°+(5x+3)°+58=180°
(10x+6)°+58°=180°
10x°+64°=180°
10x°=116°
x=11.6°
hope that helps!
Answer:
8, 9
Step-by-step explanation:
Since x > 7
This means that x cannot equal 7 but must be greater values than 7.
Thus 8 and 9 are solutions

Answer:
16x² + 8x - 15 = 0
Step-by-step explanation:
Given the roots are x = - and x = , then the factors are
(x + ) and (x - ) and the equation is
(x + )(x - ) = 0 ← expand factors using FOIL
x² - x + x - = 0, that is
x² + x - = 0 ( multiply through by 16 )
16x² + 8x - 15 = 0
