3. In a class of 50, the # of people with brown hair is 2 more than 5 times the number of people with red hair. How many
shtirl [24]

Answer:

8 red haired and 42 brown haired

Step-by-step explanation:

I chose a random number to start off with (which is 8) and I multiplied it by 5.

8•5=40 and then you have to add 2, so you get 42.

42+8 = 50

The equation would be (5x+2)+x where 'x' is the number of people with red hair.

Answer:

transitive property

Step-by-step explanation:

According to transitive property, if there is some relation between a and b by some rule , and then there same relation between  b and c by some rule, then

A and C are related to each other by some rule.

Example:

A = B

B=C

then by transitive property

A=C

As value of A and C are same that is B we can say that A is equal to C whose value is B.

_______________________________________________

Given

a =2z and 2z=b

here both c and b has value equal to Z , Thus, they follow transitive property.
