Answer:

.02mn - 0.12m -0.2

Step-by-step explanation:

.02m(n - 5) - .02(m + 10)

To get equivalent expression, remove the parenthesis

Distribute .02m inside the parenthesis

.02mn - 0.1- .02(m + 10)

Distribute -0.2 inside the parenthesis

.02mn - 0.1m- .02 m-0.2

Now combine like terms

.02mn - 0.12m -0.2

The difference of two numbers is 42. the larger number is three less than six times the smaller number. find the numbers.
IgorLugansk [536]
X and y are the numbers
x>y

diffference is 42
x-y=42

larger is 3 less than 6 times smaller
x=-3+6y

subsitute -3+6y for x

x-y=42
-3+6y-y=42
-3+5y=42
add3 to both sides
5y=45
divide both sides by 5
y=9

sub back

x=-3+6y
x=-3+6(9)
x=-3+54
x=51

the numbers are 51 and 9

690/6 = 11.5

Darina [25.2K]
X=side length of a campsite
12x(5+x)=1248  because each campsite has a length of x and there are 12                           and from the top of the camp to the water is the 5 yds + a                             side length and LW=1248
60x+12x^2=1248
12x^2+60x-1248=0
x^2+5-14=0
(x+7)(x-2)=0
x+7=0 or x-2=0
x=-7 or x=2
x=2 because width can't be negative
the width of one campsite is 2 yds
