Step-by-step explanation:

Simplifying

3x + -28 + 3x + -30 + x = 33

Reorder the terms:

-28 + -30 + 3x + 3x + x = 33

Combine like terms: -28 + -30 = -58

-58 + 3x + 3x + x = 33

Combine like terms: 3x + 3x = 6x

-58 + 6x + x = 33

Combine like terms: 6x + x = 7x

-58 + 7x = 33

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '58' to each side of the equation.

-58 + 58 + 7x = 33 + 58

Combine like terms: -58 + 58 = 0

0 + 7x = 33 + 58

7x = 33 + 58

Combine like terms: 33 + 58 = 91

7x = 91

Divide each side by '7'.

x = 13

Simplifying

x = 13

AnswerSolving

-58 + 7x = 33

Find the 7th term in the sequence -1, -3, -9,...

mestny [16]

Answer:

The answer is 729

Step-by-step explanation:

to get the next term, the sequence multiples the previous number by -3

1 * -3 = -3

-3 * -3 = 9

and so on.

To get the 7th term:

-27 * -3 = 81 (5th term)

81 * -3 = -243 (6th)

-243 * -3 = 729 (7th)

Pie

To determine the fraction of her classmates with dogs as pets, we simply multiply the two given fractions based from the survey.

Pets = (2/3)(5/6) = 5/9

Thus, there are 5/9 of Ruby;s car.

Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour, and then walked

RUDIKE [14]

The system of equations that represents this situation are:

q + p = 2

4q + 5p = 8

Solution:

Let q be the number of hours it took Courtney to walk from her house to the beach

Let p be the number of hours it took her to walk from the beach to the park

The entire walk took 2 hours

Therefore,

q + p = 2 ------- eqn 1

The total distance Courtney walked was 8 kilometers

Total distance = 8 km

Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour

Then walked from the beach to the park at a constant speed of 5 kilometers per hour

Distance is given as:

$distance = speed \times time$

From her house to the beach:

$distance = 4 \times q = 4q$

From the beach to the park:

$distance = 5 \times p = 5p$

We know that,

Total distance = 8 km

Therefore,

4q + 5p = 8 ------ eqn 2

Thus the system of equations that represents this situation are:

q + p = 2

4q + 5p = 8
