Answer:
x=36
Step-by-step explanation:
First rewrite equation then multiply each side by 36. 9x-36=4x+144.
then move the variable 9x-4x+36=144. Next subtract 9x and 4x ...5x=144+36.... 5x=180. Lastly you divide 180÷5 this your answer x=36
Answer:
Step-by-step explanation:
If the equation of the of the hyperbola is , then the eccentricity, and the directrices are and the foci are (± ae,0).
Now, given that ae = 4 and ......... (1)
So,
⇒ a² = 8
⇒ a = 2√2 units.
Now, from equation (1) we get, ae = 4
⇒ e = √2 as a = 2√2
Now,
⇒
⇒ b² = 8
Hence, the equation of the hyperbola is

On a number line, -2 appears to the right of -5, and therefore -2 is warmer than -5. (Answer A)
The difference between -2 and -5 is -2 - (-5) = 5 - 2 = 3 degrees C (Answer B)
In other words, -2 is 3 degrees C warmer than -5 degrees C.
Step-by-step explanation:
let us assume the amount of battery boxes as 3x and pen boxes as 4x
since the battery sale is 4 times more,
3 (4x) =12 x
so 4x +12x = 16x
total money received is 976 rupees
so 16x =976
x =976÷16 = 61
AMOUNT OF BATTERY BOXES =4X = 4×61= 244 BOXES
AMOUNT OF PEN BOXES = X= 61 BOXES
