Answer:
Each student gets 2 1/3
Step-by-step explanation:
So you would divide 7 by 3, which you can't...so 6 divided by 3 is 2, and when you split the last one into thirds you can each have 1/3. Add the sections together, and each person gets 2 1/3
Answer:
1/5x+51=2x+42
Step-by-step explanation:
1/5 of x, the number, plus 51 is equal to 2 times the number plus 42.
I assume that 0.53 with a bar means the decimal fraction in which 3 is repeating.
24/45, 8/15, and 48/90 all result in the same decimal value. Thus, we are simply looking for the one that is fully simplified.
The correct answer is 8/15.
Hope this helps!
Answer:
y= -1/3x+9.2
Step-by-step explanation:
I believe that it is 9.2 although it could be another number in the 9's.
The slope is (rise) -1 and (run) 3 and the line crosses the y-intercept at what it looks like 9.2
Answer:
boys = 250
girls = 150
Step-by-step explanation:
5g = 3b eq. 1
g + b = 400 eq. 2
g = girls
b = boys
From the eq. 2
g = 400 - b
Replacing this last eq. on eq. 1:
5(400-b) = 3b
5*400 + 5*-b = 3b
2000 - 5b = 3b
2000 = 3b + 5b
2000 = 8b
2000/8 = b
250 = b
From eq. 2
g + 250 = 400
g = 400 - 250
g = 150
Check:
from eq. 1
5*150 = 3*250 = 750
