Answer:
7.41, 7.6, 745
Step-by-step explanation:
When using mental math to solve problems with decimals, it is harder to keep track of what number goes where and where the decimal spot goes as well. Although, with whole numbers in mental math, it is a lot easier to solve since there is no decimal and less numbers (unless you are doing whole number math with a large amount of numbers).
Jamie and Richard are the only contestants of the election.
Jamie got 3/8 of the total votes.
Richard got = 1 - 3/8 = (8-3)/8 = 5/8 of total votes
Number of votes Richard got = 75
So 5/8 of total votes = 75
Total votes = 75 ÷ 5/8 = 75 × 8/5 = 120
Jamie got = 120 - 75 = 45 Votes
Answer:
X = -1/3, 1/3
Step-by-step explanation:
6x^2 - x = 1
(subtract 1 from both sides)
6x^2 - x - 1 = 0
(factor)
(6x - 3) (6x + 2)
(simplify)
(2x - 1) (3x + 1)
(Solve for x in each parentheses)
2x-1= 0 and 3x+1=0
X= -1/2 X= -1/3
