Step-by-step explanation:
Sum of angles in a triangle = 180°.
=> s° + (s/7 + 3)° + (s/7 - 3)° = 180°
=> 9/7 * s° = 180°
=> s° = 180° * (7/9) = 140°
Hence the value of s is 140.
Here is my expression (7x6) + 12
y – 5 = 6(x – 7)
y -5 = 6x - 42
y = 6x - 37
answer is B. (7, 5)
5 = 6(7) - 37
5 = 42 -37
5 = 5
Answer:
12
$42.00/($3.50 per gallon) = 12 gallons
If Y = 5 and the X is = 1 then Y = 125 is X = 25
