a) 3(-2) + 4(3) = -6 + 12 = 6
b) 2(-2) -3(3) +5 = -4 -9 + 5 = -8
c) 4(-2) -(3) = -8 -3 = -11
d) -(-2) -2(3) = 4 -6 = -2
e) (1/2)(-2) +(3) = -1 +3 = 2
f) (2/3)(3) -(1/2)(-2) = 2 + 1 = 3
The answer is 40.You should change the 2 2/3 to improper fraction and the times it with 15.
Answer:
5/6 4/15 1/3
Step-by-step explanation:
on a calculator divide the numerator by the denominator.
This problem is an example of an arithmetic series.
The common difference of the second term (15) with the first term (9) and the third term (21) with the second term (15) [15-9=6; 21-15=6] is 6.
The formula for solving this is:
An= A1 +(n-1)*d where An is the nth term, A1 is the first term, n is the number of terms and d is the common difference.
An=9+ (31-1)*6 = 189
The answer is 189.
If Maya only has $15 dollars to spend and she buys a notebook for $5.50 then that leaves her with $9.50 and if she has to save $7.75 then that leaves her with $1.75 and since she wants to buy cookies then you have to figure out how many cookies she can get with $1.75 plus the tax but food doesn't have tax so she can buy 7 packages of cookies since there only 25 cents is right on point at $1.75 I hope I answered your question with all the calculating I had to do and the typing I went through to explain it to you !!!!!!!!!!!!!!!!!!!!!!!! now could you please give me a thank you and hit the brain aster button please and thank you so much
