6.5 x 10 to the 3rd power
remember the base must be less than 10 and greather or equal to 1
4.2 hours x .4 gallons per hour = 1.68 gallons
Answer: -1
Step-by-step explanation:
1 - (-3) - 5 = 1 + 3 - 5
Thats because subtracting by a negative number is the same as adding the negative number's absolute value (Distance away from zero).
(1 + 3) - 5 = -1

Answer:
30degrees
Step-by-step explanation:
Given
Exterior angle m<CDE = 7x - 19 degrees
interior angles are
m<BCD = 2x - 1
m<DBC = x+10
Since the sum of the interior angles is equal to the exterior, hence;
2x - 1 + x+10 = 7x - 19
3x + 9 = 7x - 19
3x - 7x = -19 - 9
-4x = -28
x = 28/4
x = 7
Get m<CDE
m<CDE = 7x - 19
m<CDE = 7(7) - 19
m<CDE = 49 - 19
m<CDE = 30degrees
