Given
An algebraic expression is the difference between seven times a number and three times that number.
To find:
The algebraic expression.
Solution:
Let x be the unknown number.
Multiplication is used for times and subtraction is used for difference.
7 times of a number = 7x
3 times of that number = 3x
The difference between seven times a number and three times that number is
Therefore, the algebraic expression for the given statement is 7x-3x and its simplified form is 4x.
i think itss this 45 45 90 triangle ratio
In a 45 45 90 triangle, the ratios are equal to: 1 : 1 : 2 for angles (45° : 45° : 90°) 1 : 1 : √2 for sides (a : a : a√2)Jun 26, 2020
The second option is your answer.
2(1) - 3 = 2 - 3 = - 1
2(2) - 3 = 4 - 3 = 1
2(3) - 3 = 6 - 3 = 3
2(4) - 3 = 8 - 3 = 5
- 1 + 1 + 3 + 5 = 8
4/7 of 49 = 28, the reason why is because if you divide 49 into 7 different groups, you will get 7 groups of 7(7x7=49). And if you take 4 of those groups, the answer is 28(7x4=28)
