100% of something is basically the same as saying "1 times that number". This is because 100% = 1.0 or just 1. So the number will not change if you take 100% of it.
Any percent smaller than 100% will convert to a decimal number smaller than 1, which makes the final result smaller. Conversely, any percent larger than 100% is going to convert to a decimal larger than 1, making the final result larger.
The percent 175% converts to the decimal form 1.75 after you move the decimal to the left 2 spots. Multiply this value by last year's headcount (320) and we get...
175% of 320 = 1.75*320 = 560
Answer: Choice C) 560
Standard form = Ax + By = C
y = -1/3x + 4
Start by getting rid of fraction
Multiply all by 3
3y = -1x + 12
Add x to both side
x + 3y = 12
Solution: x + 3y = 12
Answer: 2x+8, 8+x
Step-by-step explanation:
You had 2(x+4), so, 2*x=2x+2*4=8 so, 2x+8
For the second one just multiply 2 and 4= 8+x all by itself =8+x
3 is one fourth of twelve, so add two counters
Answer:
17
Step-by-step explanation:
what's the value of y when x = -5?" Since x cannot = -5, then the answer is "null" or "does not exist". It's like saying "I have 4 US coins whose total value is 6 cents.
