1.8*19 a.(8*10)+(8*1) b.(8*10)+(8*9)*** c.(8*20)-1 d.(8*10)-(8*1)

Right

Thank You Ms.Sue

You're welcome, Janet.

janet you are all right

To find the answer to the equation 1.8 multiplied by 19, we can use the distributive property of multiplication over addition to simplify the expression.

Let's break down each option:

a. (8*10) + (8*1)

Here, we are multiplying 8 by 10 and 8 by 1 separately.
(8*10) = 80 and (8*1) = 8.
Adding these two results together, 80 + 8 equals 88. However, this is not the correct answer.

b. (8*10) + (8*9)

This option correctly multiplies 8 by 10 and 8 by 9 separately.
(8*10) = 80 and (8*9) = 72.
Adding these two results together, 80 + 72 equals 152.
So, the correct answer is 152.

c. (8*20) - 1

In this case, we are multiplying 8 by 20 and then subtracting 1.
(8*20) = 160.
Subtracting 1 from 160, we get 159. However, this is not the correct answer.

d. (8*10) - (8*1)

Similar to option a, we are multiplying 8 by 10 and 8 by 1 separately.
(8*10) = 80 and (8*1) = 8.
Subtracting 8 from 80, we get 72. However, this is not the correct answer.

Therefore, the correct answer is option b, which is (8*10) + (8*9) and equals 152.
