Answer:
Step-by-step explanation:Absolute value is a number's distance away from zero. For example, on a number line, -9 is 9 spaces away from zero. So, the absolut value is 9. Similarly, the number 9 is also 9 spaces from zero, so the absolute value would be 9. 9 and -9 both have an absolute value of 9. I hope this is helpful!
Answer:
X=144
Step-by-step explanation:
2X+25×9+3=0
2X+288
2X= -288
X= -144
Okay, let's find out how much the tax was by finding out what 7% of $28 is, we do this by multiplying:

Convert 7% into a decimal, we do this by dividing it by 100 because percentages are parts of 100:

Multiply:

So this is the tax. Add it to the original price to get the total price:
48(miles/hour)*(1 mi/5280 ft)(1 hour/60 min)
-----
= (48*1*1)/(1*5280*60)(ft/min)
