Answer:
A.
Step-by-step explanation:
Answer:
1) x= -36.
2) x = 0.
Step-by-step explanation:
1) Taking the 3rd power to both sides and using the following exponent law:

we get:

So this tells us that x = -36.
2) We can distribute the power inside every term. So the left side becomes:

Now, the trick here is to remember that
, so replacing 1 with
, which then gives us:
, telling us that 3x = 0 and thus, x = 0.
The number which is express in each of the models as given in the image attached to the task content are as follows;
a). 1.37
b). 1.37
c). 1.37.
<h3>What numbers are expressed according to the given models in the task content?</h3>
It follows from the task content that the models describe that One flat represents 1 whole, One rod represents 1 tenth and one unit represents 1 hundredth.
It therefore follows from the task content that in each of the models, the algebraic sum of flat(s), rods and units as the case may be results in the value; 1.37 as the utmost number represented by the models.

Answer:
Step-by-step explanation: I did a formula to get the answer
2x-10=5x-100
2x=5x-90
I subtracted 100-10 and then got 90
3x=90
3x/3x=90/3
x=30
