3) What does 7x mean?
9 answers
7x means "seven times x" or "seven multiplied by x."
3) What does 7x mean? * 1 point a number 7 plus x 7 times a number x 7 in the tens spot and x in the ones spot 7 divided by a number x
In the context of mathematical notation, the term 7x typically refers to "seven times a number x." It represents the multiplication operation where the number 7 is multiplied by the variable x.
4) Solve for 4a + 3b if a= 2 and b = 7 * 1 point 29 16 64 79
To solve for 4a + 3b when a = 2 and b = 7, we substitute these values into the expression:
4a + 3b = 4(2) + 3(7)
4a + 3b = 8 + 21
4a + 3b = 29
Therefore, when a = 2 and b = 7, 4a + 3b equals 29.
So, the correct answer is 29.
4a + 3b = 4(2) + 3(7)
4a + 3b = 8 + 21
4a + 3b = 29
Therefore, when a = 2 and b = 7, 4a + 3b equals 29.
So, the correct answer is 29.
5) Simplify. 8 x 3 + 7 x 2 - 5 * 1 point 57 155 30 33
To simplify the expression 8 x 3 + 7 x 2 - 5, we follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Given expression: 8 x 3 + 7 x 2 - 5
= 24 + 14 - 5
= 38 - 5
= 33
Therefore, the simplified value of the expression 8 x 3 + 7 x 2 - 5 is 33.
Given expression: 8 x 3 + 7 x 2 - 5
= 24 + 14 - 5
= 38 - 5
= 33
Therefore, the simplified value of the expression 8 x 3 + 7 x 2 - 5 is 33.
6) Which shows the commutative property of addition? * 1 point 4 x w = w x 4 8 + a = a + 8 4 + (n + 2) = (4 + n ) + 2 3 (p + 7) = 3p + 21
The commutative property of addition states that changing the order of addends does not change the sum.
Out of the given options, the commutative property of addition is demonstrated by:
- 8 + a = a + 8
This equation shows that the order of the addends (8 and a) can be reversed without changing the sum, which illustrates the commutative property of addition.
