Answer:
x= 14.8 -16.83
Step-by-step explanation:
Try to get x by itself
6x= 89-101
divide both sides by 6 and you get x= 14.8 -16.83
0W 6G = 1POSSIBILITY
1W 5G = 1POSSIBILITY
2W 4G, 2W 4G = 2 POSSIBILITIES
3W 3G, 3W 3G = 2 POSSIBILITIES
4W 2G, 4W 2G = 2 POSSIBILITIES
5W 1G = 1POSSIBILITY
6W 0G = 1POSSIBILITY
TOTAL IS 10 DIFFERENT CUBES
Answer:
x=2
Step-by-step explanation:
28−(3x+4)=2(x+6)+x
We need to use the distributive property for the right side.
28−3x−4=(2)(x)+(2)(6)+x)
28−3x−4=2x+2+x
−3x+24=3x+12
From here we need to subtract 3x from both side.
−3x+24−3x=3x+12−3x
6x+24=12
Transfer +24 on the right side.
6x=12−24
6x=−12
Finally, divide both sides by −6
6x/-6 = -12/-6
x=2
Any number larger than 36 would be a counter examples.
When n is equal to 36, both sides of the inequality are equal to 216. As you get larger than 36 the right side is larger than the left side. Therefore, the inequality is not true.
Answer:
number of $20 bill = 4
Number of $5 bill = 5
Step-by-step explanation:
Given that:
Total number of $5 and $20 bills = 9
Let :
Number of $5 bills = x
Number of $20 bills = y
Combined worth of all bills = $105
x + y = 9 - - - (1)
5x + 20y = 105 - - - (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
5(9 - y) + 20y = 105
45 - 5y + 20y = 105
15y = 105 - 45
15y = 60
y = 60/15
y = 4
x = 9 - y
x = 9 - 4 = 5
Hence,
number of $20 bill = 4
Number of $5 bill = 5
