Hope this helped, brainliest?

Step-by-step explanation:

Not exactly sure if there are other questions included, but to fill out the table im assuming you break up the hours and miles.

Jamal hiked 6 miles in 3 hours, first block would be 1.5miles in 45 minutes, 2nd block would be 3miles in 1hour 30minutes, 4.5miles in 2hours 15minutes, and last 6 miles in 3 hours.

For rubi it would be 2.5miles, 5miles, 7.5miles, 10miles. the time would be 1 hour, 2 hour, 3 hour, 4 hour.

If this isnt what it is asking please provide more info and i'll help

A knife is three times the cost of a spoon. 9 spoons and 12 knifes cost ?82.80 workout the cost of 1 knife.

tankabanditka [31]

Let S = spoon

Let K = knife

1 knife is thee times the cost of a spoon, so it would be 3S

Now you have 9S + 12K = 82.80

We can replace the K with 3S:

9S +12(3S) = 82.80

Simplify the left side:

9S + 36S = 82.80

Add:

45S = 82.80

Divide both sides by 45"

S = 82.80 / 45

S = 1.84

One spoon cost $1.84

We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:

Knife = 1.84 x 3 = $5.52

Solve for x : log(3x) + log(x + 4) = log(15). Please explain it to me.

zlopas [31]

Answer:

x = 1

Explanation:

$\sf \rightarrow log(3x) + log(x + 4) = log(15)$

Rule: log(a) + log(b) = log(ab)

$\sf \rightarrow log(3x(x + 4)) = log(15)$

cancel out log on both sides

$\sf \rightarrow 3x(x + 4) = 15$

relocate constant variable

$\sf \rightarrow 3x^2 + 12x -15 = 0$

take 3 as a common factor

$\sf \rightarrow 3(x^2 + 4x -5) = 0$

divide both sides by 3

$\sf \rightarrow x^2 + 4x -5 = 0$

middle term split

$\sf \rightarrow x^2 + 5x -x-5 = 0$

factor common terms

$\sf \rightarrow x(x + 5) -1(x+5)= 0$

collect into groups

$\sf \rightarrow (x-1)(x+5)= 0$

set to zero

$\sf \rightarrow x-1 = 0 , \ x+5= 0$

relocate variables

$\sf \rightarrow x = 1, \ x = -5$

There must be a positive solution for log, so the solution is only x = 1

Tyler has 45% of his pay check remaining. What fraction of his pay check does he have remaining?

Andreyy89

Answer:

If he has 45% of his cheak remaining we already have the remaining so we just to turn it into a fraction

First we put it over 100

45

100

Then we reduce it to the lowest terms

which would be
