Answer:
r =
Step-by-step explanation:
In order to make 'q' the independent variable in the equation, you need to solve for 'r'. The dependent variable would be 'r' because it depends on the value of 'q' to be solved. We can solve for 'r' by using inverse operations and completing the same operation on both sides of the equation. Starting with the initial equation and solving for 'r':
-7q + 12r = 3q -4
Add '7q' to both sides: -7q + 7q + 12r = 3q - 4 + 7q or 12r = 10q - 4
Divide all terms by 12: 12r/12 = 10q/12 - 4/12
Simplify: r =

Step-by-step explanation:
Since the base angle are congruent, both 44° then the triangle is isosceles.
Then the 2 legs are congruent, that is
4x - 7 = 2x + 1 ( subtract 2x from both sides )
2x - 7 = 1 ( add 7 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Thus legs are both 4x - 7 = 4(4) - 7 = 16 - 7 = 9 and base = x + 3 = 4 + 3 = 7
As a check 9 + 9 + 7 = 25 → correct
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the base angles from 180 for y, that is
y = 180 - (44 + 44) = 180 - 88 = 92
Finally
x = 4
y = 92
angles are 92°, 44° and 44°
sides are 9, 9 and 7
Answer:
x=31.25
Step-by-step explanation:
250+14h=22h
250=22h-14h
250=8h
h=250/8
h=31.25
