Answer:
n = 12
Step-by-step explanation:
(n-8)x 7 = 28
n-8 = 4
n = 12
Answer:
x = 2
Step-by-step explanation:
Since this is a 45-45-90 triangle, the 2 legs will be the same, meaning that y will also be 
.
We can then solve for x using the Pythagorean theorem:
Or, we could use a quicker approach: if the triangle is a 45-45-90 triangle, the hypotenuse will be times the length of 1 leg. It essentially does the same thing; it's just faster so you could save time on tests.
1 ton= 2,000 pounds
250 x 8 = 2,000
final answer: it would take the elephant 8 days to eat a ton of food

Thank you for posting your question here at brainly. Below is the solution:
m(fat) = %fat x 25,5 = 0,37 x 25,5 = 9,435 g of fat
<span>m(protein) = %protein x 25,5 = 0,28 x 25,5 = 7,14 g of protein </span>
<span>m(carbohydrate) = %carbohydrate x 25,5 = 0,04 x 25,5 = 1,02 g of carbohydrate </span>
<span>E = m(protein) x 17 + m(fat) x 38 + m(carbohydrate) x 17 </span>
<span>E = (7,14 x 17) + (9,435 x 38) + (1,02 x 17) </span>
<span>E = 497 kJ</span>
A <u>counterexample</u> is something that proves a statement, or equation, wrong. A counterexample is used in math when someone creates a theorem, writes an equation, or creates a new rule and someone proves it to be false.
<u>For Example:</u>
Let's say that I said <em>an even number plus an odd number always equals an even number</em>. A counterexample of that would be 4 + 5 = 9, because 9 is odd, therefore proving the statement wrong.
