Answer:
2 2/9
Step-by-step explanation:
2 divided by 9/10 = 2/1 / 9/10
2/1 x 10/9 = 20/9 = 2 2/9 or 2.222..
Answer:
(2,3)
Step-by-step explanation:
The solution to a linear system is always where both of the lines intersect.
Answer:
see explanation
Step-by-step explanation:
the ratio of the opposite interior angles = 8 : 9 = 8x : 9x
The exterior angle of a triangle = sum of the opposite interior angles, hence
8x + 9x = 119
17x = 119 ( divide both sides by 17 )
x = 7
8 parts = 8x = 8 × 7 = 56
9 parts = 9x = 9 × 7 = 63
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 angles from 180 for third angle in triangle
180° - (56 + 63)° = 180° - 119° = 61°
The 3 angles of the triangle are 56°, 61°, 63°
Answer:
z^2 +7z -8 = 0
Step-by-step explanation:
Let z = 3x+2. Then we can substitute z wherever we see 3x+2.
z^2 +7z -8 = 0 . . . . equivalent quadratic
__
This is easily factored to ...
(z -1)(z +8) = 0
So, the original quadratic has solutions ...
(3x +2) -1 = 0
x = -1/3
and
(3x +2) +8 = 0
x = -10/3
