Answer:
61
Step-by-step explanation:
A + B = 90
6 - 5x + 7 - 2x = 90
13 - 7x = 90
- 7x = 90 - 13
- 7x = 77
- x = 77 / 7
x = - 11
A: 6 - (5 * - 11) = 6 + 55 = 61
B: 7 - (2 * -11) = 7 + 22 = 29
Together they equal 90 as they should.
X1=radical 6--->2.44
X2=-radical 6/3--->-0.816
5x+ 10+ 15y
= 5*x+ 5*2+ 5*(3y)
= 5*(x+2+3y)
The final answer is 5(x+2+3y)~
5/12 < 3/6
The answer is <
