Answer:
-2x - 8
Step-by-step explanation:
Combine like terms
-5x - 7x = -2
Therfore you have
-2x - 8
This system will have 1 solution, or C. That's because since the equations are different, meaning that there is 1 solution.
The correct answer would be (4,-5)
9514 1404 393
Answer:
Step-by-step explanation:
The marked angles form a linear pair, so have a sum of 180°.
(4a +10) +(6a) = 180
10a = 170 . . . . . . . . . . subtract 10
a = 17 . . . . . . . . . . . . . divide by 10
__
Then the measure of angle ABC is ...
∠ABC = 4a +10 = 4(17) +10 = 68 +10 . . . . . substitute 17 for 'a'
∠ABC = 78°
300, 36 divided by 0.12 (12%) is 300
