Answer:

log₅(21) = log₅(3) +log₅(7)

Step-by-step explanation:

The relevant relation is ...

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

where the logs have any consistent base.

Here, we have ,,,

ab = 21 = 3·7.

Then ...

log(21) = log(3) +log(7)

When the logs are to base 5, that becomes ...

log₅(21) = log₅(3) +log₅(7)

Two kinds of tickets to an outdoor concert were sold: lawn tickets and seat tickets. Less than 400 tickets in total were sold. L

miskamm [114]

Answer:

Tickets to sit on the bench (b) = 150

Tickets to sit on the lawn (l) = 200

Step-by-step explanation:

Tickets to sit on a bench (b)cost $75 each.

Tickets to sit on the lawn (l) cost $40 each

350 tickets had been sold

$19,250 had been raised through tickets sales

This forms a simultaneous equation:

b + l = 350 ... (i)

75b + 40l = 19,250 ... (ii)

Multiplying (i) by 40 and (ii) by 1 we get;

40b + 40l = 14,000 ... (i)

75b + 40l = 19,250 ... (ii)

Subtracting (ii) - (i) we get;

35b = 5250

b = 5250 ÷ 35 = 150

Oksana_A [137]

Answer:

y= 1/2x+6

Step-by-step explanation:

Slope intercept form is y=mx+b, where m is the slope and b is the y intercept. Using the information given, we know the slope-intercept form of the line is y=1/2x+6
