Answer:
2 or less packs
Step-by-step explanation:
15.99 + 1.99g < 20.00 where g is the number of packs of gum
Subtract 15.99 from each side
15.99 + 1.99g - 15.99 < 20.00-15.99
1.99g < 4.01
Divide by 1.99
1.99g/1.99 < 4.01/1.99
g < 2.015075377
Harold must buy whole packs so g =2 or less
Answer:
(4,-1)
Step-by-step explanation:
You can solve this system of equations in a couple of different ways, but I'm going to use the elimination method. If you're solving a system of equations using elimination, you want to have one variable cancel out. In this case, we don't have to change anything because -3y and 3y will already cancel out if we add the two equations together. You can both add or subtract, but it's easiest to add in this case. The equation will be set up like this: 2x-3y=11
+ 7x+3y=25
--------------
After you add them together, you should get 9x=36, which you can solve by dividing both sides by 9. Then, you'll get x=4. This is your x-coordinate. Next, you want to get your y-coordinate, so you can substitute 4 into one of the two equations for x and solve for y. This will get you -1 for y. I'd also recommend checking your answer. Hope this was helpful! :)
Step One is to add up all the values
6.5+5+6+5.5+7+4+4.5+5+6+5.5+4+7.5+6+7+8+5+6+6.5+6.5+5 = 116.5
Step Two is to divide the result from step one by 20 (since there are 20 values added up)
116.5/20 = 5.825
The sample mean is 5.825
No,
A line is considered a "line segment" when a line connects to 2 points.
If a line was infinite length, it would never end up ending at one point.
Hope this was clear for you
Yes the negative exponents would only affect it by fractions. Like x^-6
is the same thing is 1/x^6. It does not affect the integer with the signs.
