Answer:
substitute the given values for m, n, and p into each problem and solve. Make sure you don't ignore minuses and negatives. Separate with parentheses to make sure you don't get confused.
Step-by-step explanation:
54: -7(-5) - 10( 3/2)
35 - 10(1.5)
35 - 15
20
55. -3mnp
-3 x (-5) x 3/2 x (-8)
15 x 1.5 x (-8)
22.5 x (-8)
-180
56. 8n / (-6p)
8(1.5) / (-6 x -8)
12 / 48
1/4 or .25
57. p squared is (-8)(-8)
2(-8)(-8)(-1.5) / (-5)
128 (-1.5) / (-5)
-192/ (-5) negatives cancel out
192/5
38.4
I think that the correct answer would be : x/5 - y = 10
I hope that this helps you !
<u>We are given:</u>
The time-traveller has 79 books, but he can only take 5 books
since we need to find the number of ways he can choose 5 books, we know that the order in which he takes the books does NOT matter
Hence, we will use combination
<u>Finding the number of ways:</u>
Since we will use combination, ₇₉C₅
We know that the formula for combination is (n!) / (r!(n-r)!)
₇₉C₅ = 79! / 5!(74!)
₇₉C₅ = 22,537,515
Therefore, the time traveller can choose 5 books in 22,537,515 different ways
The formula is
A=P(1+r/n)^nt
A future value?
P present value 1500
R interest rate 0.04
N compounded quarterly 4
T time 2 years
A=1,500×(1+0.04÷4)^(4×2)
A=1,624.29
So the answer is B
Hope it helps!
Answer:
Yes if Greg and his partner can both eat 18 inch pizza then together they can eat a 36 inch pizza
