Which expressions have products of -0.64? If they do not have a product of -0.64, explain a way to make them have that product.
a. (0.32)(-2)
b. 1.6(-4)
c. 0.64(-1)
d. (1.28)(-0.5)
e. (-4)(-0.16)
thats my choices i also need HELPPPPPP with the second one
a. .32 * 2 = .64 but the 2 has a negative sign, so it is -.64.
b. Assuming no typo, product will be greater than one.
c. Same
d. Same
e. Negative times a negative is a positive.
THANK YOU!!!!!!
To find expressions that have a product of -0.64, we can set up an equation and solve for the expressions. Let's assume we have two expressions, x and y, and their product is -0.64:
x * y = -0.64
Now, let's find expressions x and y that satisfy this equation:
1. One approach is to have one expression be a positive number and the other expression be a negative number. For example, we can take x = 0.8 and y = -0.8. Their product is indeed -0.64.
2. Another approach is to use fractions. We can choose x = 0.8 and y = -0.8/0.8, which simplifies to y = -1. These expressions also give a product of -0.64.
3. We can also use decimal numbers to solve this. Let's take x = 0.16 and y = -4. Their product is indeed -0.64.
These are a few examples of expressions that have a product of -0.64. If you don't have any expressions that give this product, you can always change the magnitudes or signs of the numbers you are using until you achieve the desired product.
