Step-by-step explanation:
(23/5)÷(-33/4)
multiply the first by the second reverse
23/5×4/-33
multiply the numerator between them and the denomination between them
92/-165
-0.558
Answer:
(4, 4)
Step-by-step explanation:
Coordinates of a point (x, y) after dilation with a scale factor k,
Rule to be followed,
(x, y) → k(x, y)
→ (kx, ky)
Coordinates of point T are (8, 8).
Dilation of the point T after dilation with a scale factor of
will be,
(8, 8) → 
→ (4, 4)
Therefore, coordinates of the image point B' will be (4, 4).
The easiest way is if it doesn't need to be simplified. Multiply -2.105 by

. You get the fraction

. While this is technically the answer, you can simplify this down to

. Because 421 is a prime number, this can not be simplified any further. Therefore, the solution is

.

.
I think that the answer is $569.8. 550 times 0.072 times 0.5 (half a year) is 19.8, then 550 + 19.8 is 569.8.
Responda:
a) 3 e 4
Explicação passo a passo:
Deixei :
Número de cães = x
Número de gatos = y
2x + 3y = 17 - - - - (1)
x - y = 1 - - - - (2)
De (2)
x = 1 + y
Coloque em (1)
2 (1 + y) + 3y = 17
2 + 2y + 3y = 17
2 + 5y = 17
5y = 17 - 2
5y = 15
y = 15/5
y = 3
x = 1 + y
x = 1 + 3
x = 4
Número de cães = x = 4
Número de gatos = y = 3
