Answer:

4/675

Step-by-step explanation:

There can be 90  two-digit numbers ranging from 10 to 99. There will be

90 x 90= 8100 possibilities of randomly selecting and combining 2 entire two-digit numbers, if we find ax b to be distinct from bx a. When 10 is first chosen, there may be 9 two-digit numbers that could be combined within the required range for a product When 11 is chosen first, then the second two-digit number has 9 possibilities. 12 has seven options; 13 has six options; 14 has five options; 15 has four options; 16 has three options; 17 has two options; 18 has 2 options; and 19 has one option. It provides us 48 total choices so the likelihood that the combination of two randomly chosen two-digit whole numbers is one of theses  these possibilities is thus 48/8100 = 4/675.

Marsha uses 8.5 pints of white paint and blue paint to paint her bedroom walls. 2/5
Serjik [45]

Answer:

5.1 pints

Step-by-step explanation:

Theres 2 ways

First way:

We can do 2/5 of 8.5 which is 3.4. Then, we can subtract 3.4 from 8.5 and get 5.1 pints.

Second way:

We can simply do 3/5 of 8.5 because the remaining 3/5 of the paint is blue. 3/5 of 8.5 is 5.1 pints

Solve for x: |4x + 12| = 16
frosja888 [35]
<span>|4x + 12| = 16
As it is in modulus function, it could be either +ve or -ve
4x+12 = 16   OR   4x - 12 = 16
4x = 16-12    OR   4x = 16 + 12
4x = 4           OR   4x = 28
x = 4/4     OR  x = 28/4
x = 1  OR   x = 7

In short, Your Answer would be either 1 or 7

Hope this helps!</span>
