There are 16 animals in a farmhouse. Some of them are chickens and the others are cows. Altogether, these animals have 60 legs. How many chickens and how many cows are in the farmhouse? -- Which two equations would you use to solve this problem? Chickens have 2 legs and cows have 4 legs.

Please mark as brainliest!!

There are 2 chickens and 14 cows.

Equations:

2x + 4y = 60

x + y = 16

Step-by-step explanation:

2x + 2y = 32

Substituting now:

32 + 2y = 60

2y = 28

y = 14

x = 16 - 14 = 2

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
