822.42 miles in 2.7 hours
304.6 × 2.7 = 822.42
Is 3 cm the height of the triangle?
Answer: -2
Step-by-step explanation:
3x+2y=16
x+y=4 multiply by -2
-2x-2y=-8
3x+2y=16 ------a
-2x-2y=-8 -------b
Add equation a and b
(3x+-2x)+(2y+-2y) = 16+(-8)
x+0=8 (y has been eliminated)
Answer:
Find something the parts of the equation (which are separated by a sign (+, -, x, or /)) and sort of un-distribute a common number out.
Step-by-step explanation:
Example: 5x + 10
Step One: Find what number they have in common. (5)
Step Two: Divide it from both parts of the equation and put it outside parentheses.
Step Three (result): 5(x+2)
