Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
Answer:
First, assign a value to x.<em> x</em> will be 2 in this case.
Next, multiply x by itself, because that is what exponent 2, or squared, means. 2 x 2 = 4
Now, multiply 4 by 7. 4 x 7 = 28
Next, find the value of <em>9x</em>.
The value of 9x will be 9 times a number, x, also known as 2 in this scenario. 9 x 2 = 18
Then, subtract 28 from 18. 28 - 18 = 10
Lastly, subtract 10. 10 - 10 = 0
Therefore,
The answer is 0. <em>Product may vary depending on value assigned to x.</em>

A unit rate compares a quantity to one unit of measure.
Well you know that the amount of boys that voted for Danny has to be 123 - 55, so you do that and get 68, then the ratio of girls to boys is 55:68, and that can't be simplified anymore because 55 has factors of only 1, 55, 11, and 5, and that doesn't get you anywhere.
