Bill ate 1/4 pound of trail mix on his first break during a hiking trip. On his second break, he ate 1/6 pound. How many pounds

tino4ka555 [31]

Since we know that he ate 1/4 pound one time, and 1/6 another time, we have to add up the fractions.

1/4+1/6

LCM of 4 and 6 = 12

3/12 + 2/12

Add the numerators:

5/12

So, he ate 5/12 of a pound of bars in both breaks.

Hope this helps!

- x - x + 11 - 2x = 83 please show step by step!!

m_a_m_a [10]

Answer:

$x=-18$

Step-by-step explanation:

Given

$-x-x+11-2x=83$

Step 1: Combine Like Terms on LHS

$-x-x+11-2x=83\\-2x+11-2x=83\\-4x+11=83$

Step 2: Subtract 11 on both sides

$-4x+11=83\\-4x+11-11=83-11\\-4x=72$

Step 3: Divide both sides by -4 to isolate the x-variable

$-4x=72\\\\\frac{-4x}{-4}=\frac{72}{-4}\\ \\ x=-18$

Final Answer

$x=-18$

Find a formula for the nth term of the geometric sequence. Assume the n begins with 1. a1=18, a2=9

LUCKY_DIMON [66]

Answer:

Option E

Step-by-step explanation:

Explicit formula of a geometric sequence is,

$T_n=a_1(r)^{n-1}$

Here, $a_1=$ First term

$r=$ common ratio

$n=$ number of terms

If, $a_1=18$ and $a_2=9$

Common ratio of the sequence $r=\frac{a_2}{a_1}$

$r=\frac{9}{18}$

$r=\frac{1}{2}$

By substituting these values in the formula,

$T_n=18(\frac{1}{2} )^{n-1}$

Therefore, Option E is the answer.
