Answer:
H) 0.75
Step-by-step explanation:
4.5 divided by 6 is 0.75
We don't use remainders in algebra for the most part. We have to do regular division. I'll try to show it here:
____._7___5_____________
6 ) 4 . 5 0
4 . 2
____________
0 . 3 0
0 . 3 0
_____________
0
Let X = number of minutes.
Plan A = 50 + 0.04X
Plan B = 60 + 0.02X
50 + 0.04X = 60 + 0.02X
Subtract 50 from each side:
0.04X = 10 + 0.02X
Subtract 0.02X from each side:
0.02X = 10
Divide both sides by 0.02
X = 10 / 0.02
X = 500
It will take 500 minutes.
1600<2570-125.5x<2000 subtract 2570 from all terms...
-970<-125.5x<-570 divide all terms by -125.5 (and reverse signs because of division by a negative!)
7.73>x>4.54 and x is months since January, and since months can only be integers...
x=[5,7]
So January + 5, 6, and 7 respectively are the three months that satisfy the equation...
June, July, and August.
Answer: 9/12
Step-by-step explanation:
1. 1/4+2/8 (common denominators)
2/8+2/8=4/8 or 1/2
2. 1/2+3/12 (common denominators)
6/12+3/12= 9/12
0.42z = 2.52
z = 2.52 / 0.42
z = 6
same as
z + 7.45 = 13.45
z = 13.45 - 7.45
z = 6
answer is top right z + 7.45 = 13.45
