You can use the following equation:
10h+3p+0.5r=100
This equation uses “h” “p” and “r” to represent the number of animals bought, each variable having a coefficient which is that animal's price. The right side is the total price.
You will now need a second equation so you can proceed to substitution/elimination:
h+p+r=100
This equation, using the same variables, represents the total number of animals to be bought.
We can eliminate the “h” variable by multiplying the bottom equation by -10, you now have the following:
10h+3p+0.5r=100
-10h-10p-10r=-1000
Add down and the result is:
-7p-9.5r=-900
You can set up a proportion
-9.5r=-900+7p
r=(-900+7p)/-9.5
And substitute in the original equation…
P.S. I challenge you to figure out the rest on your own because it is really just a tedious process of substitution and elimination from here and my phone is about to die. I'll check in later if you're still having problems.
These are the steps on how to answer your problem
Answer: just plug in the values it gives you and then it's simple addition and subtraction.
Step-by-step explanation:
I took a test yesterday with this question and got it right the answer is 3
A marching band has 1.5 times as many trumpet players as clarinet players.
i.e for every x number of clarinet players , the number of trumpet players= 1.5 x
Now, for every 2 clarinet players players, the number of trumpet players is given by 1.5=3 i’m not sure if it’s the same question but not sure
