Answer:

R__S__T

RT = RS + ST

6x – 4 = ( 4x – 3) + ST

(6x – 4 ) – ( 4x – 3 ) = ST

(6x – 4 ) +( – 4x + 3 ) = ST

2x – 1 = ST

ST = 2x – 1

RS=ST

4x – 3 = 2x – 1

4x – 2x = – 1 +3

2x = 2

x= 2/2

x =1

ST = 2x – 1 = 2(1) – 1 =2 ‐ 1 = 1

ST = 1

The ratio of girls to boys in Liza’s classroom is 5 to 4. How many girls are in her classroom if there is a total of 27 students

andrezito [222]

Answer:

$15\ girls$

Step-by-step explanation:

Let

x-----> the number of girls

y-----> the number of boys

we know that

$x+y=27$ -----> equation A

$\frac{x}{y}=\frac{5}{4}$

isolate the variable y

$y=\frac{4}{5}x$ -----> equation B

Substitute equation B in equation A

$x+\frac{4}{5}x=27$

$\frac{9}{5}x=27$

$x=5*27/9=15\ girls$
