(1 point) Mike and Lisa are brother and sister. Mike has as many brothers as sisters, and Lisa has three times as many brothers

Elza [17]

Answer:

Step-by-step explanation:

Given that Mike and Lisa are brother and sister. Mike has as many brothers as sisters, and Lisa has three times as many brothers as sisters

i.e. If Mike has x sisters, then he has x brothers.

i.e. no of sons in total = x+1 (including Mike)

No of daughters = x

Lisa's brothers = x+1 and and Lisa sisters = x-1 (exclusing Lisa)

Given that

$x+1 =3(x-1)\\2x =4\\x=2$

Hence we find that there are 3 sons and two daughters in the family.

Use set builder notation to represent the following set. {... -3, -2, -1, 0} {x | x Z, x ≤ 0} {x | x N, x ≤ 0} {x | x R, x ≤ 0}

IceJOKER [234]

Answer:

$\boxed{\boxed{\left\{x\ |\ x\ \epsilon\ Z,\ x \le 0}\right\}}}$

Step-by-step explanation:

Set builder notation-

It is a notation for representing a set by enumerating its elements and stating the properties that its members must satisfy.

The given set is,

$\left \{.... -3, -2, -1, 0 \right \}$

This set is comprised of all negative integers. So symbol Z should be used in this case.

The set builder notation for this set is,

$\left\{x\ |\ x\ \epsilon\ Z,\ x \le 0}\right\}$

hello I am trying to figure out how much rent I would have to pay if I abated the rent 30%. My rent is $610.

horrorfan [7]

If you were to get 30% backed off, lucky you !
You would then pay only the remaining 70%.

70% means 0.70

0.70 x $610 = <u>$427 </u>
