Answer:
X = 600
Step-by-step explanation:
x-(0.0765x)=554.1
x-0.0765x=554.1
0.9235x=554.1
x=600

Answer:
61,01%
Step-by-step explanation:
We must consider that her total energy intake is the addition of the energy given by the carbohydrates, fats and proteins she takes.
1g of carbohydrates contains 4kcal
1g of proteins contains 4kcal
1g of fat contains 9 kcal.
That is: 243 g of carbohidrates is equal to 972 kcal; 41g of fat is equal to 369 kcal and 63 g of proteins is equal to 252 kcal.
If we sum up all the calories she intakes in one day, the result is= 972kcal+369kcal+252kcal=1593kcal.
Now, we make a rule of 3: If 1593kcal is the 100% of the intake, then 972kcal = 972kcal*100%/1593kcal = 61,01%
Answer:
Question 2 the answer is C) y = -3/2x + 2
Question 3 the answer is D) x = 4
Step-by-step explanation:
To solve either we first need to know that parallel lines have the same slope.
So in #2 we know that the new line will also have a slope of -3/2. Therefore, we can use that along with the point given in the problem in point-slope form to get the new equation.
y - y1 = m(x - x1)
y + 1 = -3/2(x - 2)
y + 1 = -3/2x + 3
y = -3/2x + 2
And for #3, we know that we have a vertical line due to the fact that it is expressed as x = a number. Therefore, we must have the same in the answer. D is the only one that has such an answer.
I believe the answer you are looking for is 4/5.
Solution:
1/2 • 4/3=2/3
2/3÷5/6=2/3 • 6/5
4/5
