Answer:
a = -2(2x+1)-4
Step-by-step explanation:
1. Factor out the common term x.
x(4+a)= -2x(2x+1)
2. Cancel x on both sides.
4+a= -2(2x+1)
3. Subtract 4 from both sides.
a= -2(2x+1)-4
Bro the answer is obviously dababy
I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7
II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)
Answer:22.17
Step-by-step explanation:
8.65-2= 6.65
6.65/.30= 22.16666667
Round it
22.17 miles (also might round it to a while number i don’t know which they want so it could be just 22)
