please show work 3d – 4 + d = 8d – (-12)

Answers

Answer 1

Answer:

d = -4

Step-by-step explanation:

3d – 4 + d = 8d – (-12)

3d - 4 + d = 8d + 12

4d - 4 = 8d + 12

(4d - 4d) - 4 = (8d - 4d) + 12

-4 = 4d + 12

-4 - 12 = 4d (+ 12 - 12)

-16 = 4d

-16/4 = 4d/4

d = -4

Answer 2

Answer:

d= -4

Step-by-step explanation:

3d- 4 +d = 8d + 12

4d - 4 = 8d + 12

4d = 8d + 16

-4d = 16

d= -4

Check

-12 - 4 - 4 = -32 + 12

-20 = -20

The distance from the earth to the moon is two hundred thirty eight thousand, nine hundred miles. Write the distance in standard form and expanded form.

Answers

Answer:

Standard: 238,900

Expanded: 200,000 + 30,000 + 8,000 + 900

Step-by-step explanation:

The distance in standard form is 238,900 and in expanded form is 200,000 + 30,000 + 8,000 + 900.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the distance from the earth to the moon is two hundred thirty-eight thousand, nine hundred miles.

The number in standard form will be written as below:-

Standard form = 238,900

The number in the expanded form will be written as below:-

Expanded form = 200,000 + 30,000 + 8,000 + 900.

Therefore, the distance in standard form is 238,900 and in expanded form is 200,000 + 30,000 + 8,000 + 900.

-12/3*(-8+(-4)-6)+2 122 right? Travaris had always loved singing, but he was still stunned when he landed the lead role in the school musical. He could barely wait to tell his parents the news. But when he made his announcement over dinner, they looked at each other and frowned. "You said the performance was the week of May 13?" his dad asked. Travaris's heart sank. Of course. His older sister was getting married in Hawaii that week. "I'm sorry, but you'll just have to tell them that you can't do it," his mom said. The next day at school, Travaris planned to tell Ms. Phelps, the theater director, that she should give his part to someone else because he wouldn't be in town during the performance. But all day he was bombarded with congratulations from his classmates for getting the lead role. He didn't have the heart to tell them that it was all for nothing because he couldn't even be in the play. Travaris told his mom that he was staying after school to help out with set design, but really he was reading his lines, singing the songs, learning the dance numbers, and even getting fitted for costumes. It couldn't hurt to enjoy being the star of the play for a little bit, could it? But as the weeks went by, Travaris started to feel guiltier and guiltier. He knew that the longer be put off dropping out of the play, the more he would hurt the rest of the cast and crew. Finally, Travaris told Ms. Phelps how he couldn't be in the musical. Ms. Phelps thanked him for letting her know. "But don't forget to audition again next year," she added with a wink. Which of the following best describes the main theme or lesson of the story.A.
