A. given
b. distributive property (a(b+c)=ab+ac)
c. addition or commutative property (a+b=b+a)
d. subtraction property of equality (if a=b, then a-c=b-c)
e. division property of equality (if a=b, then a/c=b/c)
f. equality property (if a=b, then b=a)
Answer:
16
Step-by-step explanation:
The number would be:
= 2 + (-6 + 20)
= 2 - 6 + 20 = 16
Hope this right because your question is not very clear! :3
First, you have to set up two equations.
X + y = 45
18x + 24y = 1,050
To do this, you have to solve for an exponent by cancelling out the other one. To solve for y, you multiply everything in the first equation by -18.
-18x -18y = -810
This cancels out the x and leaves you with 6y = 240. Divide both sides by 6 and you have the number of Yankee hats that were bought.
Then, you have to substitute 40 for y in the first equation and solve for x.
12-5i + -3 + 4i
you will put them in brackets
(12-(5*i)) + (-3 +4*i)
is equal to 9-i
Hope this Help!
Answer:
6.3 or 6 3/10 pounds
Step-by-step explanation:
First you convert 8 3/4 into a decimal.
8 3/4 = 8.75
You then subtract 8.75 and 2.45.
8.75 - 2.45 = 6.3
6.3 as a fraction is 6 3/10
Therefore, he has 6.3 or 6 3/10 pounds of fudge left.
Hope this helps:)
