Answer:
x = - 5
Step-by-step explanation:
3x - 3 - 6x = 12
group like terms
3x - 6x - 3 = 12
add similar elements
- 3x - 3 = 12
add 3 to both sides
- 3x - 3 + 3 = 12 + 3
simplify
- 3x = 15
divide both sides by 3
- 3x / 5 = 15 / - 3
simplify
x = - 5
I think it’s can’t be determined because we need to know at least 2 angles of a train for.
Answer:y =-9,-8,-7,-6,-5
Step-by-step explanation:
Is this what you need? To find the y values you take an x value and subtract 7. Like the first one -2 would turn into -9
Answer: This result is not unusual.
So, it does not seem that the claimed rate of 16% is wrong
Step-by-step explanation:
Since we have given that
n = 100
p = 0.16
q = 1 - 0.16 = 0.84
So, Mean would be
and standard deviation would be
Now, if there are 19 green,
so, we will check how it is far,
Since it is 0.817 standard deviations away from the mean.
So, this result is not unusual.
So, it does not seem that the claimed rate of 16% is wrong.
Hey there!!
Let us take the cost of the belt as ' x '
Then, the cost of the shoes would be ' 7x '
Cost of the shirt would be ' x + 45 '
Cost of belt + cost of shoes = 152
x + 7x = 152
8x = 152
x = 152 / 8
x = 19
Cost of belt = $19
cost of shirt = 19 + 45
= $64
Hope helps!
