VashaNatasha [74]

Answer:

1. z = -15

2. p = 7

3. h = -11

4. t = 14

5. q = 12

Step-by-step explanation:

1.

\frac{z}{-5}+1=4

Add -1 both sides,

\frac{z}{-5}+1-1=4-1\\\frac{z}{-5}=3

Multiply both sides by -5,

\frac{z}{-5}\times-5=3\times-5\\z=-15

2.

Distribute 3 in p+2 and then add -6p and -6 both sides.

3(p+2)=6p-15\\3\times p+3\times2 = 6p-15\\3p+6=6p-15\\3p-6p=-15-6\\-3p=-21\\p=\frac{-21}{-3}=7

3.

\frac{h-7}{2}=3(h+8)

Multiply both sides by 2,

\frac{h-7}{2}\times2=3(h+8)\times2\\h-7=6(h+8)\\h-7=6h+48

Add -6h and 7 both sides,

h-6h-7+7=6h-6h+48+7\\-5h=55\\h=\frac{55}{-5}\\h=-11

4.

4t+2-5=3(t+7)-9\\4t-3=3t+21-9\\4t-3=3t+12

Add -3t and 3 both sides.

4t-3t-3+3=3t-3t+12+3\\t=15

5.

2(q-4)=4(q-8)\\2q-8=4q-32

Add -2q and 8 both sides.

2q-8-4q+8=4q-4q-32+8\\-2q=-24\\q=\frac{-24}{-2}\\q=12

Therefore,

1. z = -15

2. p = 7

3. h = -11

4. t = 14

5. q = 12

Directions: Answer true or false. If false, provide a counterexample.
Arisa [49]

Natural numbers are closed under division: false.

A set is closed under a certain operation if the results of that operation are always inside that set.

So, if natural numbers were closed under division, the division of two natural numbers would always be a natural number.

You have plenty of counterexamples, to pick one you may divide any odd number by 2: 5/2 is not a natural number.

Negative numbers are closed under addition: true.

Let m,n be two positive numbers. So, -m,-n are two negative numbers. Their sum is

(-m)+(-n)=-(m+n)

And since m+n is positive, we deduce that -(m+n) is negative, so the sum of two negative numbers is still negative.

Prime numbers are closed under subtraction: false.

This would mean that the subtraction of two primes is also a prime. Again, there are many counterexamples: 7 is prime and so is 3, but their difference 7-3 is 4, which is not prime.
