Answer:
d
Step-by-step explanation:
7x + 2 and 10x - 9 are same- side interior angles and sum to 180° , that is
7x + 2 + 10x - 9 = 180
17x - 7 = 180 ( add 7 to both sides )
17x = 187 ( divide both sides by 17 )
x = 11 → d

Answer:
The greatest possible value of 3x - 2y is 20
Step-by-step explanation:
3x - 2y ------- 1
For getting the greatest possible value we must get the greatest value available, which is 10 and put it in place of x .
As 2y is being subtracted in the eq 1, we must put the smallest value available in the eq 1 to get the greatest possible result.
put x = 10 and y = 5 in eq 1
3(10) - 2(5)
= 30 - 10
= 20
Smallest possible value from the eqaution will be obtained by putting y = 10 and x = 5
3 (5) - 2 (10)
= 15 - 20
= -5
