9% is equivalent to 9 / 100 = 0.09 as a decimal fraction.
So the tax on $3,000 = 3000 * 0.09 = $270

Answer=875miles 17.5miles per gallon
350miles x miles
________=_________
20gallons 50gallons
cross multiply
20x=17500
divide both sides by 20
x=875
875 miles can be traveled with 50 gallons of gas.
To find gas milage, which is essentially miles per gallon, simply divide the number of miles by the number of gallons
350miles 20gallons
350/20=17.5 miles per gallon
Hii
Hope u understand... Thats the value of angle E
Wade wants to have at least $55 left, so the sign will be ≤ (greater than or equal to 55) One sweater costs $12. You can use x to represent an unkown number of sweaters, so $12x. You are subtracting 12x by your budget of $175. When put together, the inequality is $175-$12x ≤ $55.
Now to solve. You want to get x alone so subtract 175. You must do this to both sides. Now you have -12x≤ -120. Divide both sides by -12 and your final answer is -120/-12 ≥ 10. (Notice the sign changes when you divide by a negative)
So Wade cannot buy more than 10 sweaters to have $55 left over. Phoo that was a workout. It can be difficult but once you get the hang of it it comes easy. If you need more help just ask :D
If it is a right triangle, then one of the angles is 90°. We are also given another angle of 15°. The angles in a triangle add up to 180°, therefor to find the missing angle we must add the known angles together and subtract this value from 180:
180 - (90 + 15)
= 180 - 105
= 75°
