The question is saying that if you buy 5 lbs, you have to pay $2.49. That means that 1 lb is $2.49/5 which (rounded to the nearest cent) is $0.50
It was a debate between the northerners and southerners (forgive my spelling). The northerners feared the addition of more slave states and a corresponding lack of reprenestation of their intrests in the North. For the southern slave holders, new western lands would be a boon (helpful) to enslaved people and the Louisiana purchase threatened to entrench and expand their suffering to western territories.
I got this on Khan Academy
Answer:
-6x-22
Step-by-step explanation:
-6 -2 (3x + 8)
Distribute the 2.
-6 -6x -16
Rewrite the expression.
-6x -6 - 16
Subtract -6 from 16.
The answer is -6x-22
Answer:
A
Step-by-step explanation:
Find the rise over run (gradient) between two points. Choosing x=-2 and x=1 we get (1 - - 2) / (4 - 7) = -3/3 = -1. This means that m in y=mx+c is -1 so it is either A or C. If we then try a pair of x and y with y = -x + c we can get c. Using the first pair: 7=-1*-2+c = 2 + c so c = 5, leaving us with y = -x + 5.
Alternatively try all 4 with the numbers, if plugging in that value of x gives you that value of y then it is the correct equation.
It's kinda hard to see the top 2 so I wont answer them only because I can't see it clear enough and I don't want to give the wrong answer because i thought it said something else but i can help with #10, anyway here's what I got it might not be fully right because I'm learning this same thing, but I'm pretty good with it.
#10. Since a triangle has a total measure of 180 degrees, you have to figure out how to get each angle to equal 180 when all 3 are added together, so here's how you solve it:
Step 1- Figure out what X represents in this question. Let's start with angle W. They already give you part of the equation, which is W= x +6. So now the next angle is X which the equation is X= 5x-12. The 3rd angle is Y= 7x-48.
Step 2- Add/ subtract the equation for each angle, and write what you got for your answer after each equation.
Step 3- After you have done step 2, try to mess around with each angle (multiply,subtract, etc.) until you got the angles to where they equal to 180 when added together.
Step 4- Write down the value of X in the blank that helped you solve the question. Do the same thing for the 3 angles.
I'm not giving the answer, but do the steps and you will be able to get it. It also helps you so you can do these on ur own.
I don't know if these are the steps u were taught, but this is how my math teacher taught me and the class.
Hope this helps, tell me if it got u the right answer or not!! :-)
