The answer is x = 60 degrees
If a + b + c = − 2 a+b+c=−2a, plus, b, plus, c, equals, minus, 2 and x + y = 1 0 x+y=10x, plus, y, equals, 10, what is − 9 a + 2

Does it have to be simplified or Into a improper fraction or a mixed number
In 3 months the cost will be the same, they will both cost $440, A is expressed as Cost = 305 + 45m (months) while B is expressed as Cost = 350 +30m because their cost will be the same equation A will equal equation B, 305 +45m = 350 +30m, subtract 30m from both sides to get 305+15m = 350, then subtract 305 from both sides to get 15m = 45, divide by 15 to get m to get m=3 which equals to x=3 input x in both equations to get your y, y = 45(3) + 305 and y= 30(3) + 350, they both give you the answer y= 440 so the point they intersect at is (3,440)
Answer:
Step-by-step explanation:
Wanda reaches hector at 4.5h. Wanda can not reach hector before the race ends, since at the speed he is going (16m / h) he would reach when both are at mile 72 and the race is 42 miles.
Wanda needs to increase her speed to 21m / h to catch Hector at the finish line.I attach the answers.
