Answer:
12s - 16t
Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
Answer:
Krutika gets 27 sweets
Step-by-step explanation:
Let
x ---> number of sweets that Caroline gets
y ---> number of sweets that Krutika gets
z ---> number of sweets that Natasha gets
we know that

so

----> equation A

----> equation B
---> equation C
Caroline gets 9 more sweets than Natasha
so
---> equation D
substitute equation D in equation B

solve for z


therefore
Krutika gets 27 sweets
Hello! thanks for asking this question! -0.75 should be your answer. Please tell me if I was right!
Answer:
D is correct. 
Step-by-step explanation:
We are given the root of the equation

If we are given solution of the equation then find equation using formula.
If a and b are the solution of equation then equation would be (x-a)(x-b)=0
Here, 
Equation form would be 
Now we simplify the above equation to get correct option.


So, D is correct. 
<h3><u>The system of linear inequalities to model the situation are:</u></h3>

<em><u>Solution:</u></em>
Let "x" be the time spent in dog walking job
Let "y" be the time spent in car wash attendant
Given that,
<em><u>You can work at most 20 hours next week</u></em>
"at most" means "less than or equal to" 20
Therefore,

Also given that,
Your dog- walking job pays $7.50 per hour
Your job as a car wash attendant pays $6 per hour
<em><u>You need to earn at least $92 to cover you weekly expenses</u></em>
"at least" means "greater than or equal to" 92
Thus, a inequality is framed as:


Thus eqn 1 and eqn 2 is the system of linear inequalities to model the situation
