7m + 2 = 6n - 5<br> Write a formula for f(m) in terms of m.

vlada-n [284]

Answer: m = 6/7n-1

Step-by-step explanation: to get 7m alone dirst we must subtract 2 from both sides so 2-2 = 0 and -5 - 2= -7 so 7m= 6n-7 and divide both sides by 7 to get m alone so 6n divided by 7 = 6/7n and -7 divided by 7 equals -1 so we're left with m= 6/7n-1

Can you answer these 3 questions for me plz

finlep [7]

A.
$1hr \: 15min = 75min$

$c = 0.22t = 0.22 \times 75 = 16.5$

cost is $16.50

B.

$26.40 = 0.22 \times t$

rearrange to solve for t:

$t = \frac{26.40}{0.22} = 120min$

C. This is the same as part B, only the rate changed

$t = \frac{26.40}{0.25} = 105.6min$

they ask for the greatest number of minutes, so we round down (take the floor of the value).

the answer is 105 minutes.
