To solve this problem, let us first assign some variables.
Let us say that the numbers are:
x = the variable representing the first number
y = the variable representing the second number
z = the variable representing the third number
From the given problem, we know that:
<span>x + y + z = 102 --->
1</span>
<span>z = 4 x --->
2</span>
<span>x = y + 6 --->
3</span>
Rewriting equation 3 in terms of y:
<span>y = x – 6 ---> 4</span>
Combining equations 1, 2 and 4 to express solely on x:
x + (x – 6) + (4 x) = 102
6 x – 6 = 102
6 x = 108
x = 18
From equation 2:
z = 4 (18)
z = 72
From equation 4:
y = 18 – 6
y = 12
Hence, the numbers are:
x = 18
y = 12
<span>z = 72</span>
Answer:
the probability that the next gumball that comes out will be neither yellow nor blue = 6/17
Step-by-step explanation:
neither yellow nor blue gumball = pink gumball = 6
3 yellow + 8 blue + 6 pink = total =17
Answer:
See explanation
Step-by-step explanation:
When you reflect across the y axis the numbers stay the same but the x coordinates become negative.
So the new coordinates are:
F(-4, 6)
G (-9, 6)
H (-7, 1)
I (-4, 0)
J (-1, 3)
Answer:
194
Step-by-step explanation:
The probability of the coin landing on heads is 0.5
Therefore, an estimate of the number of times the coin landed on heads would be 388 x 0.5 = 194
