Solve for z: 4 (z+6) -11 = 25<br> I need to show my work
mafiozo [28]

Answer:

z=3

Step-by-step explanation:

4(z+6)-11=25

add 11 to both sides

4(z+6)-11+11=25+11

simplify

4(z+6)=36

divide each side by 4

(4(z+6))/4=36/4

Simplify

z+6=9

subtract 6 from each side

z+6-6=9-6

simplify

z=3

Given three different prime numbers <img src="https://tex.z-dn.net/?f=p_1%20%5C%20%5C%20%3B%20%5C%20%5C%20p_2" id="TexFormula1"
Stels [109]

Answer:

  • 19982

Step-by-step explanation:

As we know all primes but 2 are odd numbers.

It means sum of any 3 primes not including 2 is odd.

Since we have sum of 202, one of our primes is 2.

Sum of the other two primes is 200.

In order to have maximum value of p*(200 - p) these two numbers must be closer to each other. So we are looking for two primes around 100.

<u>We can test all primes less than 200:</u>

  • 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, and 199

<u>The 3 primes with max product are:</u>

  • 2, 97, 103

<u>The value is:</u>

  • 2*97*103 = 19982
