4y - 7 = 5 - 2y
Add 2y to both sides.
6y - 7 = 5
Add 7 to both sides.
6y = 12
Divide both sides by 6
y = 2
Let x be the common factor between chickens and ducks. Then:
6x/(5x-63)=3/1
15x-189=6x
9x=189
x=21
6x=123 chickens were on the farm
☺☺☺☺
Pedro = 280 + x
ricky = x
280 + x + x = 2672
2x = 2392
x = 1196
pedro = 1476, ricky = 1196
hope this help
Answer:
If an object moves along a straight line, the distance traveled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.
Step-by-step explanation:
Answer:
Those two are vertically opposite angles
Step-by-step explanation:
So they are equal.
So,
106=6x+10
6x=106-10=96
X=96÷6=16
