Answer: Attached.
Step-by-step explanation:
Either solve the equations directly, or graph them and look for the point of intersection.
7. (150 cal)/(3/4 serving) = 150/1 / 3/4 = 150/1 * 4/3 = 200 cal/serving
The second attachment I solved in your another question.You may refer to that.
#1
Apply Pythagorean theorem
x²=10²-6²
1,743 rounded to the nearest ten is 1,740.
503 x 3 = 1509
But, it you want to estimate it I would say 1500.
