For option d:
5x - 7y = 10 . . . . . (1)
10x - 14y = 8 . . . . (2)
(1) x 2 => 10x - 14y = 20 . . . . . (3)
(2) - (3) => 0 = -14 [not possible]
Therefore, the set of equations in option d, has no solutions.
Answer:
Just use math
way
Step-by-step explanation:
Im not the best with these, but I believe it C.
The third angle is 180-55-65 = 60°.
Exterior angles are 180-55 = 125°, 135°, 120°
Hi I did a plug and play because I don’t know how else to do it.
So I started adding numbers till the tarts equal 20 and then the cherries in the tarts equals 89.
11tarts times* 5cherries is 55 black cherries
7tarts times * 4 cherries is 28 red cherries
2tarts Times* 3 cherries is 6 white cherries
20 tarts and 89 cherries
So with the information☝️in the constraints that makes the statement true above... There are 9 more black tarts on tray than white.
