Answer:
A has 263 calories
B has 257 calories
Step-by-step explanation:
system of equations:
a + 2b = 777
2a + b = 783
I multiplied the first equation by -2 to eliminate the 'a' terms
-2a - 4b = -1554
+ <u> 2a + b = 783</u>
-3b = -771
b = 257
solve for 'a'
a + 2(257) = 777
a + 514 = 777
a = 263

Answer: 51 liters of fuel are required
Step by step: start by seeing how many times 476 can go into 1428
(1428/476=3)
Then take your sum of that and multiply it by 17 since that’s the number that correlates with 476
(17x3=51) therefore your answer is 51 liters
Answer:
B) -|x + 3| = 3
D) |x + 3| + 6 = 3
Step-by-step explanation:
A) |x + 3| = 3
B) -|x + 3| = 3
Divide by -1
|x + 3| = -3
Absolute values are 0 or positive so this cannot have a solution
C) |x + 3| + 3 = 3
Subtract 3 from each side
|x + 3| + 3-3 = 3-3
|x + 3| = 0
D) |x + 3| + 6 = 3
Subtract 6 from each side
|x + 3| = -3
Absolute values are 0 or positive so this cannot have a solution
Tax is 5% of the original price. So if i multiply by 20 i can easily find the original 100%.
20 x $43 = $860
You can check if by doing 860 x 0.05 = $43
