The answer to Your question is 146.25
Answer:
Step-by-step explanation:
use uv rule= uv'+vu'
u=3x+7
u'=3+0=3
v=8x-5
v'=8-0=8
uv= (3x+7)(8)+(8x-5)(3)
=24x+56+24x-15
=48x+41
They are already in order 6 × 2/5, 3 2/3 × 2/5, 2/7 × 2/5, 2/2 × 2/5

Step-by-step explanation:
Answer:
x = -2
y = 3
Step-by-step explanation:
-5x + 3y = 19
x = 3y - 11
-5x + 3y = 19
-5(3y - 11) + 3y = 19
-15y + 55 + 3y = 19
-15y + 3y + 55 = 19
-12y + 55 = 19
-12y = 19 - 55
-12y = -36
y = -36/-12
<u>y = 3</u>
x = 3y - 11
x = 3(3) - 11
x = 9 - 11
<u>x = -2</u>
