First step is to find R
use The equation QR =43
R=43/Q
now since we have R plug that into PR= 9x - 31
P(43\Q) = 9x - 31
P43/QP +31 =9x
9x=P43÷QP +31
x=P43÷QP+31 /9
Since the question doesnt specify to leave the question in terms of P or Q i suppose this is the final answer
Hope this helps! xD
would not mind if you put it as the brainliest answer
For this case we have the following function:
We must find the value of the function for 
We have then:
Rewriting the function we have:
Answer:
The value of g (-5) is given by:
......................................................................................
Short answer: 375 grams
Remark
You only need to set up a direct proportion
Givens
flour for 12 cakes = 150 grams
Number of cakes initially = 12
Amount of flouer for 30 cakes = x
Number of cakes = 30
Proportion
amount flour for 12 cakes / 12 cakes = x / 30
Sub and solve
150 grams / 12 cakes = x / 30 cakes Cross multiply
150 * 30 = 12 *x Multiply the left side.
4500 = 12 x Divide both sides by 12
4500/12 = x
375 grams for 30 cakes. <<<<< Answer
