sveta [45]

Answer:

Tim read 54 pages on Thursday.

Step-by-step explanation:

Consider the provided information.

Tim read 2 pages on Monday. Each day after that, he reads triple the number of pages as the previous day.

Monday = $2=2$

Tuesday = $2\times 3=6$

Wednesday = $2\times 3\times 3=18$

Thursday = $2\times 3\times 3\times 3=54$

Hence, Tim read 54 pages on Thursday.

Algebra I

Average Rate of Change: $\displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1: Define

Interval -1 ≤ x ≤ 3

a = -1, b = 3

f(a) = f(-1) = 4

f(b) = f(3) = -4

Step 2: Find Average

Substitute in variables [ARC]: $\displaystyle \frac{f(3) - f(-1)}{3 + 1}$
Substitute: $\displaystyle \frac{-4 - 4}{3 + 1}$
[Fraction] Subtract/Add: $\displaystyle \frac{-8}{4}$
[Fraction] Divide: $\displaystyle -2$

Solve – 6(x – 3) + x + 3 = -9 for x.

soldi70 [24.7K]

Answer:

In this equation, the value of x is equal to 6.

Step-by-step explanation:

We are given an algebraic equation in which we need to solve for x.

We can use several properties and algebraic methods to solve this equation.

$\displaystyle -6(x - 3) + x + 3 = -9$

Firstly, we want to use the distributive property to evaluate the first term in the equation: -6(x - 3).

$-6(x - 3) + x + 3 = -9\\\\-6x + 18 + x + 3 = -9$

By distributing the -6 through, we get -6x and positive 18. Then, we need to begin combining like terms. Let's start with our constants (or the terms without a variable).

$-6x + 18 + x + 3 = -9\\\\18 + 3 = 21\\\\-6x + x + 21 = -9$

Then, we can combine our terms with variables.

$-6x + x + 21 = -9\\\\-6x + x = -5x\\\\-5x + 21 = -9$

Now, we can use the subtraction property of equality which states that if we subtract a term from one side of an equation, we must also subtract it from the opposite side. Therefore, we want to get x by itself, so we can subtract 21 from both sides using the subtraction property of equality to do this.

$-5x + 21 = -9\\\\-5x + 21 - 21 = -9 -21\\\\-5x = -30$

Finally, we can use the division property of equality and divide both sides of the equation by -5 to isolate x.

$\displaystyle -5x = -30\\\\\frac{-5x}{-5} = \frac{-30}{-5}\\\\x = 6$

Therefore, by solving the multi-step equation, we solved that x = 6.
