Answer:

Step-by-step explanation:

In similar triangles, the corresponding sides are in same proportion.

$\sf \dfrac{4x}{3x+1}=\dfrac{15}{12}$

Cross multiply,

4x*12 = 15*(3x + 1)

48x = 15*3x + 15*1

48x = 45x + 15

48x -45x = 15

3x = 15

x = 15/3

x = 5

If g(x)=2x-5 and f(x)=-x+3, which of the following represents f(g(x))?

Slav-nsk [51]

Answer: f(g(x))=-2x+8

*Note: you did not provide answer choices, but this should be the answer.

Step-by-step explanation:

f(g(x)) means you plug in g(x) into f(x).

f(g(x))=-(2x-5)+3

f(g(x))=-2x+5+3

f(g(x))=-2x+8

is asking how many batch of biscuits can $\frac{3}{5}$ cup of flour make

so solve this divide 3/5 by 3/10 to find the number of batches

$\frac{3}{5} /\frac{3}{10}$ = $\frac{30}{15 }$ = 2 +1
