divide 28 by 4
multiply seven by 2 which is fourteen
Multiply it by (2/7), (4/7), (6/7), (8/7) etc.
negative seven, but if you were subtracting -2 from -5 it would be -3
9
The missing number is 21. The reason is because you are adding seven and then subtracting one. You start out with 3 (3 + 7 = 10) then (10 - 1 = 9) then (9 + 7 = 16) and so on.
Seven less than 100 is 93. You can find this by subtracting 7 from 100. Therefore, 100 - 7 = 93.
Adding 1 then adding another one which creates seven. Before the seven the number 1 is added just like it did on the 5 to 6.
To express "seven increased by a number," you can use the variable ( x ) to represent the unknown number. The mathematical expression would be written as ( 7 + x ). This indicates that you are adding the number ( x ) to seven.
Five less than seven and two tenths is calculated by subtracting five from 7.2. This gives us 7.2 - 5 = 2.2. Therefore, the number that is five less than seven and two tenths is 2.2.
The numerical expression for seven increased by the quotient of a number and eight can be written as ( 7 + \frac{x}{8} ), where ( x ) represents the number. Here, the expression captures the idea of adding seven to the result of dividing the number ( x ) by eight.
Two squared is 4, and eight squared is 64. Adding these values together with seven gives you 4 + 7 + 64 = 75. Then, subtracting four results in 75 - 4 = 71. Thus, the final answer is 71.
