Answer:
x = 8; y = 2.5.
Step-by-step explanation:
As we know , when two complex numbers are equal their real as well as imaginary part are equal.
So comparing on both sides ,
2x = 16 and 5 = 2y
x = 8 and y = 2.5.
So , x = 8; y = 2.5.
Answer:
50
Step-by-step explanation:
let the number be x
15% of x= 0.15x
0.15x=30
(divide both sides by 0.15)
x= 200
25% of 200 = 25/100 *200
= 50
To figure this one out just add the sale price to the difference
149+35=184
the original cost was $184
I hope I've helped!
Answer:
Step-by-step explanation:
Given
Quadrilateral QRST
Q (1, 2), R (3, 4), S (5, 6), and T (2, 7)
Dlated Factor = 2
Required
Coordinates of quadrilateral Q′R′S′T′
<em>Provided that a quadrilateral is dilated with the center of dilation at the origin; the new dilated shape is simply the multiplication of the dilation factor by the coordinates of the original shape;</em>
<em />
In other words,
Q'R'S'T' = Dilation factor * QRST
When Q = (1,2)
Q' = 2 * (1,2)
Q' = (2,4)
When R = (3,4)
R' = 2 * (3,4)
R' = (6,8)
When S = (5,6)
S' = 2* (5,6)
S' = (10,12)
When T= (2,7)
T' = 2 * (2,7)
T' = (4,14)
Hence, the coordinates of Q'R'S'T' is
Q' = (2,4); R' = (6,8); S' = (10,12); T' = (4,14)
