Hi
1) -m^4n^-5= -m^4n^5
2) -4x^-1y^3= -4y^3/x
3) 2yx^-5= 2y/x^5
4) 3nm^-4=3n/m^4
5) 3x^3y^-5=3x^3/y^5
6) -5m^0n^-2= -5/n^2
7) 4x^-5y^2= 4y^2/x^5
8) 2m^-3n^4= 2m^3n^4
9) 4x^-3y^5= 4y^5/x^3
10) 2m^-1= 2/m
11) -5u^-3y^0= -5/u^3
12) -x^-2y^4= -y^4/x^2
Finally :)
I hope that's help and good luck !
Use parentheses to make the equation true: 9-8x2-1=3
Rachel's speed is 38 m/s.
Equations are mathematical statements with twoalgebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
D = -38t + 220
So, t = 1
D = -38t + 220
D = -38(1) + 220
D = -38+ 200
D = 182 m
So, v = / t
v = ( 220- 182) /1
v = 38 m/s
Hence, Rachel's speed is 38 m/s.

Answer: 38 meters per second
Step-by-step explanation:
It will take 10 people working 10 hours per day about 2.5 days to make 10 units of the product.
From the statement of the question; 15 people working 5 hours per day can make 30 units of a product in 10 days. Hence, the number of units that can be made in a day is;
Number of units per day = (15*5*10)/30
= 25 units/day
Now; if 10 people make 10 units, working 10 hours per day, it will take them x number of days.
x = (25*10)/10*10
x = 2.5 days
