P = 2d
d = 2n.....n = 1/2d
q = d - 3
since dimes is mentioned in relation to quarters, pennies, and the nickels, u would use d as ur variable
ur expression would be : d + (2d) + (1/2d) + (d - 3) = total amount of coins...then u would solve for d, the number of dimes. And once u know that, u can sub that answer back into ur original equations to find the number of pennies, quarters and nickels
4x - 26 = 3x + 4
-3x -3x
x - 26 = 4
+26 +26
x = 30
Since the 2 angles are opposite of each other you would set them equal to each other.
3, because negative numbers are less than positive numbers. Therefore, 3 is correct
Answer:
x=-1
Step-by-step explanation:
