Answer: The answer to this problem is 178 calories.
Step-by-step explanation:
To calculate the answer, simply get the percentage of calories a person would burn during exercise (I am using a calculator BTW).
185 / 260 = 0.711538462
Then, calculate 71.1538462% of 250 pounds.
250 * 0.711538462 = 177.884616
Finally, round up your answer. 177.884616 rounded up is 178.
Answer:
x=2 and y= -3
Step-by-step explanation:
This is a simultaneous equation. To solve this type of equation, there are three methods; substitution, Elimination and Graphical.
But here, we would be using the substitution method.
3x-y=9 Equation 1
2x-y=7. Equation 2
Getting y from equation 2, we have
-y= 7-2x
Multiply both sides by -
y= 2x-7 Equation 3
Substituting y for 2x-7 in equation 1, we have
3x- (2x-7)=9
3x-2x+7=9
x+7=9
x=9-7
x=2
Substituting x as 2 in equation 3
y=2x-7
y= 2(2)-7
y= 4-7
y= -3
THE STEPS AND ANSWER IS IN THE PICTURE
