there are some chickens and cows on a farm. putri counted 75 heads while ayu counted 200
legs. how many more chickens than cows are there?

There are 25 more chickens than cows

Step-by-step explanation:

a chicken only has one head so there are obviously 75 chickens

a cow has 4 legs so 200÷4=50

now, all you have to do is subtracts 75 and 50 which equals 25 :)

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
