Answer:
D
Step-by-step explanation:
A = (a + b)/2 * h
4 = (a + b)/2
(a + b) = 8
(1+7), (2+6), (3+5), (4+4)
Therefore there are 4 possibilities.
Your max amount for this is $20. Let's say x represents the number of gallons.
20 ≥ 3.2x
x = 6.25 gallons
If they're asking for integers or whole numbers, you'd round down to 6 because you only have enough money for 6 full gallons. If you rounded up to 7, you wouldn't be able to fill it up completely because then you'd be over your $20.00 budget for gas.
Answer:
120 degrees the sum of all angle is 720 degrees In the above
According to Order of Operations rules, we must multiply before adding or subtracting.
With this in mind, notice that the first operation is mult.: (-5)(-4) = +20.
At the end is another mult.: -4(6) = -24.
So, write -20 - 6 - 24. End result: -50
