kobusy [5.1K]

Answer:

81 sheep were there on the farm

Step-by-step explanation:

Consider the provided information.

Let x represents the number of goats.

y represents the number of cows.

z represents the number of sheep.

Therefore, the total number of animals are x+y+z

2/5 of the animals were goats. This can be written as:

$\frac{2}{5}(x+y+z)=x$

There were three times as many sheep than cows.

$z=3y$

There were 45 more goats than cows,

$x=45+y$

Substitute the value of x and z in equation 1.

$\frac{2}{5}(45+y+y+3y)=45+y$

$\frac{2}{5}(45+5y)=45+y$

$2(9+y)=45+y$

$18+2y=45+y$

$y=27$

Hence, there are 27 cows.

Substitute the value of y in $x=45+y$

$x=45+27$

$x=72$

Therefore, there are 72 goats.

Substitute the value of y in $z=3y$

$z=3(27)$

$z=81$

Thus, there are 81 sheep.

How do you solve this?

shutvik [7]

Answer: X=5

Step-by-step explanation:

-8=(X+11)/-2

* start by multiplying both sides by -2

16=X+11

*subtract 11 from both sides

5=X

Range of f(x)=-x+5 with domain of [-3,2] in the same notation as the domain.

Oksi-84 [34.3K]

The range would be [8, 3]

In order to find the range, simply plug each end of the domain into the equation.

f(x) = -x + 5

f(-3) = -(-3) + 5

f(-3) = 3 + 5

f(-3) = 8

Then the other side

f(x) = -x + 5

f(2) = -2 + 5

f(2) = 3
