Answer:
Number of blue marbles = 86.
Step-by-step explanation:
Let number of blue marbles = x, then the number of red marbles = 106-x.
From the second relation given in the question:-
x = 4(106 - x) + 6
Solving for x:-
x = 424 - 4x + 6
5x = 430
x = 86 blue marbles.
B, -3x+15=23 is the answer
Answer:
9, 10
Step-by-step explanation:
square root of √93 is 9.64.
Thus, we see that the number 9.64 is greater than but less than 10.
On number line it can be represented as
-∞ _____________7___8___9__9.64___10___11_______+∞
Thus, we see that the two whole numbers between which √93 lies is 9, 10
Answer:
22,23,24
Step-by-step explanation:
Well, you need to first find two consecutive integers that add up to 47, because that is the difference between the first digit and the total. This happens to be 23 and 24. Once you get these two numbers, the 22 comes intuitively, as you have to add 23 and 24 to get a difference between 22 and (22+23+24).
Step-by-step explanation:
we can factor out z
so that'll be
z((1/m)-(1/n))=1
divide by the value in parentheses on both sides
z=1/((1/m)-(1/n))
I can't tell if there's more the problem wants you to do. I could rewrite the equation on paper more easily, but I don't have one on hand
