Explanation:
Simply enter the appropriate values into x and y.
1.13(4) + 21.5(-2.35) + 13.22
= 4.52 – 50.525 + 13.22
= -32.785
Explanation:
Please define y as height and x as seconds. Calculate the number of seconds till the height is zero by setting up an equation. Find x = 206.897 by solving for 0 = 30000 - 145x. The 206.897 seconds must be converted because the answers are presented in minutes and seconds. Divide 206.897/60 to get 3.448. It's critical to keep in mind that the.448 represents a percentage of a minute rather than seconds. 3 minutes and.448(60) = 26.88 seconds.
Explanation:
Multiplication is used in a geometric sequence to go from one value to the next. The next value in an arithmetic sequence is reached through addition. The next value is increased by 2, resulting in this sequence.
Explanation:
In order to determine the roll price of Brand A, we must construct an equation. We are aware that the price of a pack of Brand B is 12*1.74 = 20.88. Additionally, we are aware of Brand A's pack price. Simply divide the pack price by the number of rolls (20.88/8 = 2.61) to get the price per roll.
Explanation:
Rewriting the equation 3x-2(2x+3) = 5 first makes it simpler to approach even though it is not essential. Give the -2 a distribution of 3x - 4x -6 = 5 using the formula. Next, gather related terms: -x = 11. X finally equals -11.
Explanation:
Distribute 5x + 15 = 3x -15 first via both sets of parentheses. Collect similar phrases 2 times for a total of -30. X finally equals -15.
Explanation:
The veteran must pay 115-115*.2 ($92) or 115*.8 ($92) in total. The senior pays $65 (115 minus $50). The senior receives a better deal.
