NARA [144]

So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.

Tickets to a school play cost $3 for students and $8 for adults. On opening night, $1000 was collected and 150 tickets sold. How

vesna_86 [32]

Let the number of students who bought tickets be s,
Let the number of adults who bought tickets be a,

Equation 1:

$3s \: + \: 8a \: = \: 1000$

Equation 2:

$s \: + \: a \: = \: 150 \\ s \: = \: 150 \: - \: a$

Substitute ( 2 ) into ( 1 ),

$3(150 \: - \: a) \: + \: 8a \: = \: 1000 \\ 450 \: - \: 3a \: + \: 8a \: = \: 1000 \\ 5a \: = \: 550 \\ a \: = \: 110$

Substitute a = 110 into ( 2 ),

$s \: + \: 110 \: = \: 150 \\ s \: = \: 40$

Ans: 40 Student Tickets, 110 Adult Tickets

Solve for x. logx+log3=log18

ad-work [718]

Answer:

The value of x in log x + log 3 = log 18 is 6.

Solution:

From question, given that log x + log 3 = log 18 ---- eqn 1

Let us first simplify left hand side in above equation,

We know that log m + log n = log (mn) ----- eqn 2

Adding log m and log n results in the logarithm of the product of m and n (log mn)

By using eqn 2, log x + log 3 becomes log 3x.

log x + log 3 = log 3x ---- eqn 3

By substituting eqn 3 in eqn 1, we get

log 3x = log 18

Since we have log on both sides, we can cancel log and the above equation becomes,

3x = 18

$x = \frac{18}{3} = 6$

Thus the value of x in log x + log3 = log18 is 6
