Multiply and reduce to lowest terms. Convert into a mixed number if necessary.

WARRIOR [948]

Answer: 1 3/12

Step-by-step explanation: You can multiple straight accross and

5 is equivelant to 5/1 so we would do

5/1 * 3/12 = 15/12 which can get simplified into 1 3/12

Hopt this helps :D

1. Solve the system of equations 3r – 4s = 0 and 2r + 5s = 23.

GaryK [48]

4s = 3r
<span>s = 3/4*r </span>
<span>plug this into the second eqution and solve for the other variable: </span>
<span>2r +5(3/4)r = 23 </span>
<span>23/4*r = 23 </span>
<span>r = 4 </span>
<span>plug this r into the above equation we solved: </span>
<span>s = 3/4*r </span>
<span>s = 3/4*4 </span>
<span>s = 3 </span>
<span>system is: </span>
<span>{r=4, s=3}</span>

If cde is a straight angle, de bisects gdh, m gde = (8x-1), m edh = (6x-15), and m cdf= 43, find each measure.

Sergio [31]

Answer:

x = 7°

<GDH = 112°

<FDH = 192°

<FDE = 135°

Step-by-step explanation:

If DE bisects <GDH this means that <GDE = <EDH

Given <GDE = (8x+1)° and <EDH = (6x+15)° then;

8x+1 = 6x+15

8x-6x = 15-1

2x = 14

x = 7°

Since <GDH = <GDE + <EDH

<GDH = 8x-1+6x+15

<GDH = 14x+14

<GDH = 14(7)+14

<GDH = 98+14

<GDH = 112°

For <FDH,

Note that sum of angle on a straight line is 180°

<FDH = <FDG + <GDE + <EDH

<FDH = <FDG + <GDH

<FDG = 180-(43+8x+1)

<FDG = 180-44-8x = 136-8x

<FDH = 136-8x+112

<FDH = 248-8x

<FDH = 248-8(7)

<FDH = 248-56

<FDH = 192°

For <FDE;

<FDE = <FDG + <GDE

<FDE = 136-8x+8x-1

<FDE = 135°

1 /4, 4/9,9/16,16/25,... please find the next two terms, nth term and 10th term of the given sequence.

frosja888 [35]

Answer:

See below in bold.

Step-by-step explanation:

Note that the numerators are the squares of 1, 2 3, 4 ...... and the denominators are the squares of 2, 3, 4, 5.....

The next 2 terms are 25/36 and 36/49.

The nth term is n^2 / (n + 1)^2 where n is the sequence number.

The 10th term is 10^2 / 11^2

= 100/121.

At the movie theatre, child admission is $6.10 and adult admission is $9.90. On Friday, four times as many adult tickets as chil

Lena [83]

Answer:

26 child tickets

Step-by-step explanation:

4c = a to make the adult tickets equal to the child tickets multiply the child tickets by 4. then use substitution.

6.10c + 9.90(4c) = 1188.20

6.10c +39.6c = 1188.20

45.7c = 1188.20

c = 26
