<h2><u>
k = 35</u></h2>
Let's solve your equation step-by-step.
14=k(0.4)
Step 1: Simplify both sides of the equation.
14=0.4k
Step 2: Flip the equation.
0.4k=14
Step 3: Divide both sides by 0.4.
= 
<h3><u>
k=35</u></h3>
Answer:
4 less kilgrams than previous weight
Step-by-step explanation:
Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:

Since both expressions are equal to y, you have to equal both expressions like this:

Now you can solve the equation:

Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result

So, the answer is x=10 and y=-1
Answer:
Step-by-step explanation:this is confusing for me oof
Y=2/3x+2/3 bc slope is 2/3 and 4-2/4-1=2/3
