Answer:
No such triangle can exist. Any of the described relations may be in error.
Step-by-step explanation:
Taken at face value, the sum of the lengths of the sides is ...
x + x + (3x-10) = 5
5x = 15
x = 3
so the third side is 3·3 -10 = -1 in length. No such triangle can exist.
If one side is actually 3x-10, the perimeter must be greater than 6 2/3 and less than 40.
If the perimeter is actually 5, then the third side must be 3x-7.5 or an expression with an even smaller constant.
So, the mistake could be in copying any of the numbers, or in copying the multiplier in the description of the 3rd side. There is insufficient information to tell exactly what the mistake is.
Answer:
The y-coordinates are the same.
Step-by-step explanation:
Since the y of (6, 9) and (6, -9) is different is because one of them has a positive y and the other order pair has a negative y.
Food A contains 150 calories in 3/4 of a serving
Food A will contain (150 x 4)/3 = 200 calories in 1 serving.
Food B contains 250 calories in 2/3 of a serving
Food B will contain (250 x 3)/2 = 375 calories in 1 serving.
Food A has fewer calories per serving.
