First multiply 3 and the 1
Then simplify b^2-4b+3=0
Then divide both numbers by 3 (b-3/3)(b-1/3)=0
If it doesn’t go in even like the second term then bring it before the B
Then equal both terms to 0 and solve
Answer:
Step-by-step explanation:
1). 10 = 
10(7 + x) = 1 + 7x
70 + 10x = 7x + 1
10x - 7x = 1 - 70
3x = -69
x = -23
2). 0.2 = 
0.2(12 + x) = 6 + 2x
2.4 + 0.2x = 6 + 2x
2.4 - 6 = 2x - 0.2x
1.8x = -3.6
x = -2
3). 0.8 = 
0.8(x + 0.5) = x
0.8x + 0.4 = x
x - 0.8x = 0.4
0.2x = 0.4
x = 2
4). 3.5 = 
3.5(0.5 - x) = 4 + 2x
1.75 - 3.5x = 4 + 2x
-3.5x - 2x = 4 - 1.75
-5.5x = 2.25
x = -
x = -
4 bags of sugar have 6kg or 6000 grams.
how many in each box?
well, there are 4 boxes, how many times does 4 go into 6000? 1500.
that many grams in 1 box then.
Answer:
2.75 or 2 3/4
Step-by-step explanation:
1 + 1 = 2
1/4 + 1/2 = 3/4
1/4 = 1/4
make 1/2 into 2/4
add 1/4 to 2/4
3/4
2 + 3/4 = 2 3/4 or 2.75
