If You can pls answer all 4 with the equations •What is the value of the expression
6x - 2y +5y when x=10 and y=3?

•If x - 16 = 29, what is the value of 2(x + 5)

•What is the value of 3n² - 4m ÷ 6 when n=4 and m=18?

•Find the value of (⅑)³​​

9514 1404 393

Step-by-step explanation:

Put the numbers where the variables are and do the arithmetic. Your calculator can help.

1. 6x -2y +5y = 6(10) -2(3) +5(3) = 60 -6 +15 = 69

__

2. add 16 to find x.

  x -16 = 29

  x = 45

Then do the substitution:

  2(45 +5) = 2(50) = 100

__

3. 3(4²) -4(18) = 3(16) -4(18) = 48 -72 = -24

__

4. (1/9)³ = (1/9)(1/9)(1/9) = 1/(9·9·9) = 1/729

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
