Answer:
9/4
Step-by-step explanation:
see image
2/3 is 2 × 1/3.
We can separate the exponent into 1/3 power raised to the 2nd power. 1/3 power is the same as cube root.
27 and 8 are both perfect cubes. 3^3 and 2^3.
Thats how you go from 27/8 to 3/2.
Then square it.
see image.
15.
You'd get this by multiplying the -10 by 3 then adding it to both sides. Then divide by 5.
Here we need to convert 2. 1 cm to mm .
And for that we will use the following conversion .
1cm = 10 mm
So for 2.1 cm, we will multiply 2.1 and 10 to convert it to mm. Therefore 2.1 cm = 2.1* 10mm = 21mm
And that's the required answer .

Step-by-step explanation:
Equation
-5(-3x+1)=-45 If this is not correct, leave a comment please.
Solution
-5(-3x+1)=-45 Divide by -5
-5(-3x + 1)/5 = -45/-5
(-3x + 1) = 9 Remove the brackets
-3x + 1 = 9 Subtract 1 from both sides
-3x + 1 - 1 = 9 - 1 Simplify
-3x = 8 Divide by -3
-3x/-3 = 8/-3
x = -8/3
or
x = -2.66
or
x = - 2 2/3
