You would do n+n+1= 575 and then you add all the n's and that's 2n + 1 = 575 them subtract 1 from 575 and then the problem would be 2n = 574 then
then you'd get 287. Get it?
Answer:
0.0028
Step-by-step explanation:
move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive)

Answer:
5. x=21.9 units
6. x=14 units
7. x=31.7 units
Step-by-step explanation:
5. Assuming that the line through the middle of the triangle in 5, we can split the 18 units side into 9 and 9. Using pythagorean theorem (a^2+b^2+c^2), we can find that x is equal to making x . Rounding to the nearest tenth, we get x is about 21.9 units
6. By doing pyth. th. on one of the triangles, we get sqrt(361-289) which is sqrt(72), which is about 8.5 units. Subtracting 8.5*2 from 31, we get 14 for x
7. by doing pyth th on the smaller triangle, we get sqrt 228 and now we can do pyth th again with 28 (44-16) and sqrt228, which turns out to be sqrt (784+228) which is sqrt (1002), which when rounded the nearest tenth is 31.7
Good Luck!
For this case we propose a system of equations:
x: Variable representing the amount of oranges
y: Variable that represents the amount of grapefruit
We have to meet a citrus gift package:
From the second equation we have to:
We replace in the first:
Thus, the package has 3 grapefruits.
On the other hand:
Thus, the package has 9 oranges.
Answer:
9 oranges
