What is the solution of -2x = -16

1 answer:

7 0

Divide both sides by -2

two negatives make a positive and that's true so x = 16/2 so divide it

x = 8 because 2 x 8 = 16 and 2/16 = 8 so true.

Answer: x = 8.

Margret is inviting 3 friends to a party. If each friend will get 8 cookies and each box has 6 cookies, how many boxes does Marg

Alisiya [41]

Answer:

Margret need to get 4 boxes of cookies.

Step-by-step explanation:

Total friends = 3

Cookies each friend will get = 8

Each box has cookies = 6 cookies

How many boxes does Margret need to get?

Total cookies will be= Total friends x Cookies each friend will get

Total cookies will be= 3 x 8 = 24

If one box has 6 cookies and we need total 24 cookies so, divide 24 by 6 to get number of boxes

Number of boxes = Total cookies/ number of cookies in one box

Number of boxes = 24/6

Number of boxes = 4

So, Margret need to get 4 boxes of cookies.

A leading bank is coming up with an investment that pays 8 percent interest compounded semiannually. What is the investment's ef

uranmaximum [27]

The effective rate is calculated in the following way:
$r = {(1 + \frac{i}{n} )}^{n} - 1$
where r is the effective annual rate, i the interest rate, and n the number of compounding periods per year (for example, 12 for monthly compounding).
our compounding period is 2 since the bank pays us semiannually(two times per year) and our interest rate is 8%
so lets plug in numbers:
$r = {(1 + \frac{8\%}{2}) }^{2} - 1 \\ r = {(1 + \frac{1}{25}) }^{2} - 1 \\ r = \frac{676}{625} - 1 \\ r = 0.0816 \: or \: 8.16\%$

please help me it is URGENT pls the first one is solve and the 2nd one is simplify I will give u lots of points thank you

klasskru [66]

I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7

II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)
