Answer:

x=1.714285714 or x=1.71

Step-by-step explanation:

Distribute 8 to x and 8 (8x+64)

Get rid of -13x on the other side of the equation by doing +13x to both sides.

That should leave you with 21x+64=100.

Subtract 64 from both sides of the equation.

21x=36

Divide 21 from both sides which will leave you with the answer as a long decimal so round it.

x=1.71

The shown pair of angles are Co interior angle pair, therefore the sum of those angles is 180°

$\qquad \sf \dashrightarrow \: 130 \degree + 7x + 1 \degree = 180 \degree$

$\qquad \sf \dashrightarrow \: 131 \degree + 7x = 180 \degree$

$\qquad \sf \dashrightarrow \: 7x= 180 \degree - 131 \degree$

$\qquad \sf \dashrightarrow \: 7x= 49 \degree$

$\qquad \sf \dashrightarrow \: x=49 \degree \div 7$

$\qquad \sf \dashrightarrow \: x=7 \degree$

The required value of x is 7°

"A serving of fish contains 50 g protein and 4 g of fat. If protein has a caloric value of 4 kcal/g and fat has 9 kcal/g, how ma

evablogger [386]

Answer: 236 kcal

Step-by-step explanation:

Given : A serving of fish contains 50 g protein and 4 g of fat.

i.e. content of protein = 50 g

content of fat = 4 g

Also, The caloric value in protein = 4 kcal/g

The caloric value in fat = 9 kcal/g

Calories in 50 g protein = (content of protein)x (caloric value in protein )

= 50g x 4 kcal/g = 200 kcal

Calories in 4 g fat= (content of fat)x (caloric value in fat)

=4 g x 9 kcal/g = 36 kcal

Then, the total calories in the serving will be :Calories in 50 g protein + Calories in 4 g fat

= 200 kcal+ 36 kcal =236 kcal

Hence, there are 236 kcal in the serving.
