A Farmer Was On His Tractor And Drove By Some Chickens And Pigs In His Field He Counted 30 Heads And

Answers

Answer 1

Answer:

There are 18 pigs and 12 chickens.

Step-by-step explanation:

p = # of pigs

c = # of chickens

I'm assuming each animal has one head and all the pigs have 4 legs and all the chickens have 2 legs, therefore:

p+c = 30

4p+2c = 84

Elimination:

-2(p+c = 30)        -2p -2c = -60

4p +2c = 84         4p +2c = 84

                            2p    =     24

                               p    =    12

Now substitute p for 12:

12 + c = 30

c      =    18

Check:

4(12) + 2(18) = 84

48     + 36    = 84

84 = 84

There are 18 chickens and 12 pigs.

Find the value of y = 500 -25x
for x = { -3, 2, 5}

Answers

Answer:

575, 450 and 375

Step-by-step explanation:

Find the value of y = 500 -25x

for x = { -3, 2, 5}

Given the function y = 500-25x

When x = -3.

y = 500-25(-3)

y = 500+75

y = 575

When x = 2

y = 500-25(2)

y = 500-50

y = 450

When x = 5

y = 500-25(5)

y = 500-125

y = 375

Hence the required values are 575, 450 and 375

Which expressions are equivalent to − 90 − 60 w?

Answers

Answer:

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

Using distributive property:

A : -30(3+2w)  =  -90 - 60w          : equivalent to -90 - 60w

B : (-9-6w) ⋅ 10  = -90 - 60w          : equivalent to -90 - 60w

C : -3(30 - 20w)  = -90 + 60w       : NOT equivalent to -90 - 60w

D : (6 + 4w)×15  = 90 + 60w          : NOT equivalent to -90 - 60w

E : −20(4.5 + 3w) = - 90 - 60w     : equivalent to -90 - 60w

SO THAT MEANS

A : -30(3+2w)

B : (-9-6w) ⋅ 10

E : −20(4.5 + 3w)

2x + 4y = -4

-6 -6y + 5y = 1

-6 -y = 1

-y = 1 + 6

x = 12
