O 15
Answer:
A. -15
Step-by-step explanation:
First, ignore the negative sign and simply pretend the problem is asking for the product of 3 and 5.
When multiplying a by b, it's essentially the same as adding a to itself b times. Here, we multiply 3 by 5, so add 3 to itself 5 times: 3 + 3 + 3 + 3 + 3 = 15.
Now, look at the negative sign. When we multiply two numbers of different signs (one is negative and one is positive), the result is always negative. However, when we multiply two numbers of the same sign (either both positive or both negative), the result is always positive.
Here, we have one negative and one positive, which means the result should be negative. So, add a negative sign to 15 to get -15.
The answer is A.
Answer:
-15
Step-by-step explanation:
Product of a and b is:
a × b
Similarly, the product of -3 and 5 is:
-3 × 5
-15
The value of the solution of expression is, x = 11
We have to give that,
An expression to simplify,
4x - 7 = 2x + 15
Now, Simplify the expression by combining like terms as,
4x - 7 = 2x + 15
Subtract 2x on both sides,
4x - 2x - 7 = 15
2x - 7 = 15
Add 7 on both sides,
2x - 7 + 7 = 15 + 7
2x = 22
Divide 2 into both sides,
x= 22/2
x = 11
Therefore, the solution is, x = 11
