Answer:
z = 5/2y -1
Step-by-step explanation:
We observe that z has ...
- 1 added
- the sum multiplied by 2/5
To solve for z, we undo these operations in reverse order.

Answer:
The first one is incorrect
Step-by-step explanation:
I'm sorry if this is wrong...
Factor and group common ones
60=2*2*3*5*x*x*x*x*y*y*y*y*y*y*y
45x^5^5=3*3*5*x*x*x*x*x*y*y*y*y*y
75x^3y=3*5*5*x*x*x*y
the commmon gropu to all is 3*5*x*x*x*y=15x^3y
It depends on the question given, for example
you can do distributive property will multiplying.
Example 1:
there is two ways on doing distributive property.
I can do 4(8+3)
add 8+3 since it is inside the parenthesis which equals = 11 then multiply the outside on what you added. 4x11= 44
example 2: I can also do it another way. 4(8+3) distribute the 4 by multiplying the 4 with both numbers. 4x8 and 4x3 which equals 32, and 12. add 32+12=44
so either way you will get the same answer. hope I helped.
