Answer:
each bundle weighs 68.5 lb
Step-by-step explanation:
6165/ 90
4x+20=5y
Divide 5 on both sides
so your answer would be
4/5x+4=y
x+15=3y
Divide 3 on both sides
so your answer would be
3x+5=y
8 21/100
Hope this helped :)
A. 4x+5=4x-5
4x+10=4x
10=0
B. 4x+5=4x+5
C.4x+5=1/4+5
4x=1/4
16x=1
x=16
D. 4x+5=8x+10
-4x=5
x=-5/4
A. has no solution
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
