Choice (B) is true.
For (A): 5 is not a divisor of 14, whose only divisors are 1, 2, 7, and 14.
For (B): the factors of 10 are: 1, 2, 5, and 10. The factors of 15 are: 1, 3, 5, and 15. As we can see, the only, and greatest, common factor is 5.
For (C): 3 is not a factor of 13, which is a prime number.
For (D): again, 3 is not a factor of 14.
Answer:
b
Step-by-step explanation:
Because y is squared, or, actually, because (y + 6) is squared, we know immediately that the graph is horizontal. Because both (y + 6)^2 and (x - 7) are positive, we know that the graph opens to the right. (b) is correct.
Answer:
x > -3/7
Step-by-step explanation:
Eliminate parentheses, collect terms, and subtract the constant on the left.
5(3 -x) -4(2 -3x) > 4
15 -5x -8 +12x > 4
7x +7 > 4
7x > -3
x > -3/7 . . . . . divide by the coefficient of x
Answer:
$0.65
Step-by-step explanation:
x=cost of washcloth
x+1.20=cost of towel
Now,
x+x+1.20=2.50
2x=1.30
x=0.65
So, cost of washcloth is $0.65
