Answer:

C) h(x)=-1.3-1.75x

f(x)=3.7-2x

g(x) = 0.25x-5

f(x) + g(x) =3.7-2x + 0.25x-5

Combine like terms

= -1.75x - 1.3

Keep in mind we'll convert the mixed fractions to "improper" and then proceed, also keep in mind that minus times minus is plus,

$\bf -5-\cfrac{5}{3}\impliedby \stackrel{LCD}{3}\implies \cfrac{(-5\cdot 3)-(5\cdot 1)}{3}\implies \cfrac{-15-5}{3}\implies \cfrac{-20}{3}
\\\\\\
{-6\frac{2}{3}}\\\\
-------------------------------\\\\
-1\frac{1}{3}-1\frac{2}{3}\implies -\cfrac{1\cdot 3+1}{3}-\cfrac{1\cdot 3+2}{3}\implies -\cfrac{4}{3}-\cfrac{5}{3}$

$\bf \stackrel{LCD}{3}\implies \cfrac{-4-5}{3}\implies \cfrac{-9}{3}\implies -3\\\\
-------------------------------\\\\
-\cfrac{1}{2}-\left(-\cfrac{5}{9} \right)\implies -\cfrac{1}{2}+\cfrac{5}{9}\impliedby \stackrel{LCD}{18}\implies \cfrac{(-1\cdot 9)+(5\cdot 2)}{18}
\\\\\\
\cfrac{-9+10}{18}\implies \cfrac{1}{18}$

Stacey is selling tickets to the school play. The tickets are $8 for adults and $3 for children. She sells twice as many adult t

Leona [35]

48 adult tickets and 24 children tickets were sold.

Step-by-step explanation:

Given,

Cost of one adult ticket = $8

Cost of one child ticket = $3

Total worth of sold tickets = $456

Let,

Number of adult tickets sold = x

Number of child ticket sold = y

According to given statement;

8x+3y=456 Eqn 1

x = 2y Eqn 2

Putting value of x from Eqn 1 in Eqn 2

$8(2y)+3y=456\\16y+3y=456\\19y=456$

Dividing both sides by 19

$\frac{19y}{19}=\frac{456}{19}\\y=24$

Putting y=24 in Eqn 2

$x=2(24)\\x=48$

48 adult tickets and 24 children tickets were sold.
