Answer:
Step-by-step explanation:
(2x + 3) (-x - 2)
distribute first term, to the second term:
2x(-x) + 2x(-2) + 3(-x) + 3(-2)
multiply:
+ (-4x) + (-3x) + (-6)
combine the like terms:
- 4x - 3x - 6
-7x
- 7x - 6
final answer :
- 7x - 6
hope this helped !!
mark me brainliest :D
The coins differ in value by 5¢, so swapping the numbers of them will change the value by 5¢ for each unit difference in the numbers of coins. Since
40¢ = 8 * 5¢
there must be 8 more dimes than nickels.
There are (22 +8)/2 = 15 dimes and 7 nickels.
_____
You could write some equations for this problem. Let n, d represent numbers of nickels and dimes.
.. n +d = 22
.. 10d +5n - (10n +5d) = 40 . . . . . . . cents
.. 5(d -n) = 40 . . . . . . . . . . . . . . . . . . reversing the coin count changes the total by 5 cents for each unit of difference (d -n), as stated above.
.. d -n = 8 . . . . . . . . . . . . . . . . . . . . . . divide the preceding equation by 5
Adding this last equation to the first gives
.. 2d = 22 +8
.. d = 30/2 = 15
.. n = 22 -15 = 7
There are 15 dimes and 7 nickels.
The smaller rectangle is like a smaller version of the big one, and 8 divided by 2 is four... so I think you need to divide 18 by 4, which is 4.5, so C is the answer
Answer:
The answer is A. It's too garlicky
Step-by-step explanation:
To solve this take not Emily believes 8 cloves in every 500ml of sauce is perfect. Now take note raphael's sauce is 12 cloves for every 900 ml.
First divide 500 by 8
500/8= 62.5
So Emily believes every 62.5 ML needs a clove of garlic.
Now divide 900 by 12
900/12=75
Raphael's sauce has one clove of garlic for every 75 ml.
Answer: d. $1,432.50
Step-by-step explanation:
Sales price + Rush charge = 35 * 1.25 = $43.75
Add tax;
= 43.75 * 1.08
= $47.25
Total purchase = 47.25 * 30 units
= $1,417.50
Total cost of purchase = 1,417.50 + 15 (shipping)
= $1,432.50
