3x - y = 0 . . . (1)
5x + 2y = 22 . . . (2)
From (1), y = 3x . . . (3)
Putting (3) into (2) gives:
5x + 2(3x) = 22
5x + 6x = 22
11x = 22
x = 2
From (3), y = 3(11) = 33
x = 11, y = 33.
Answer:
30% of 90
30% x 90
30/100 =3/10
3/10 x 90 = 270/10
270 = 27
90 - 27 = 63
Keisha has to read 63 more minutes to reach her goal.
Answer:50,400
Step-by-step explanation:
The distance between -2 and -1 1/2 is 1/2:
-2+1/2=-1 1/2
-1 1/2 =-1 1/2
I was trying to show my work but hope this could help you
If you would like to evaluate u + xy, you can do this using the following steps:
u = 18, x = 10, y = 8
u + xy = 18 + 10 * 8 = 18 + 80 = 98
The correct result would be C. 98.
