Combine all the like terms on one side:
 0.8x-4.3x+1.2x=7.7-3.2
-2.3x=4.5
Use the division property of equality. divide both sides by -2.3.
That leaves you with x=-1.96 (when rounded). exact: -1.95652

On the left side of the equation we have like terms so: -3.5x + 3.2 = -1.2x + 7.7
Add 3.5 to each side: 3.2 = 2.3x + 7.7
Subtract 7.7 from each side: -4.5 = 2.3x
Divide both sides by 2.3: -1.95652174 = x
Answer: -1.95652174

Which of the following is the graph of the solution set of t – 4 ≥ 4t + 8 or 3t >14 – 4t?
Stells [14]

Answer:

Option (C)

Step-by-step explanation:

There are two inequalities,

t - 4 ≥ 4t + 8 ------(1)

3t > 14 - 4t ------(2)

By simplifying inequality (1),

t - 4 ≥ 4t + 8

t ≥ 4t + 8 + 4

t ≥ 4t + 12

t - 4t ≥ 12

-3t ≥ 12

t ≤ \frac{12}{(-3)}

t ≤ -4

By solving inequality (2),

3t > 14 - 4t

3t + 4t > 14

7t > 14

t > \frac{14}{7}

t > 2

From the given graphs, Option (C) will be the answer.

The expression 148 – 24d gives the number of pizzas a store has in stock, where d is the number of days. How many pizzas will th
Feliz [49]

Explanation

A function is defined as a relation between a set of inputs having one output each,in this case our independent variable is the number of days( d) and the dependent variable would be the number of pizzas

so

Step 1

let the function

\begin{gathered} P=148-24d \\ where\text{ P is the number of pizzas } \\ and\text{ d is the number of days} \end{gathered}

therefore, to know the number of pizzas are in the stock after 5 days we need to evaluate the equation for d=3

so

\begin{gathered} P=148-24d \\ let\text{ d=5 and evaluate} \\ P=148-24(5) \\ P=148-120=28 \\ P=28 \end{gathered}

so, after five day there willbe 28 pizzas in stock

I hope this helpsyou
