This equation can be expressed as: abs(55- 4x) = 15, where abs = absolute value. x can equal 10 or 17.5.
6x - 7 = x + 38 Add '7' to both sides 6x = x + 45 Subtract 'x' from both sides 5x = 45 Divide both sides by '5' x = 9 The NUMBER !!!!!
To find 7 percent of a number, multiply the number by 0.07. In this instance, 0.07 x 57140 = 3999.8. Therefore, 7 percent of 57140 is equal to 3999.8.
To find 3 times 2.7 using a quick picture, you can represent 3 as three groups of equal parts and 2.7 as a decimal number. Draw three equal groups and divide each group into tenths to represent 2.7. Count the total number of tenths in the three groups, which equals 8.1. Therefore, 3 times 2.7 is equal to 8.1.
To find 2 percent of a number, multiply that number by 0.02. In this instance, 7000 x 0.02 = 140. Therefore, 2 percent of 7000 is equal to 140.
There are many fractions that are equal to one fifth. To find them, you multiply any whole number, (1/5 times 2) and find the answer. (2/10) When you reduce two tenths, (or any fraction) divide 2/10 by 2 and get 1/5. Two tenths and one fifth are equal.
