Answer:
Step-by-step explanation:
Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...
x + (x+40) = 1180
2x = 1140 . . . . subtract 40
x = 570 . . . . . .divide by 2
x+40 = 610 . . . . the speed of the faster plane
The two speeds are 570 mph and 610 mph.
Answer: -3x+5y=-2 = x=5/3y+2/3
3x+7y=26 = x=-7/3y+26/3

Answer:
200
Step-by-step explanation:
The reason why this answer is 200 is because it gave us a clue that 30 students said that pie was their favorite desert, what is half of 30? 15 so therefore, the pattern is half of each.
Ice cream: 35x2=70
Cake: 27x2=54
Candy: 23x2=46
Pie: 15x2=30
So, 70+54+46+30=200
Hope it helpsssss !!!!!!!
