last math help please?

Question

Given the formula k=LMN, what is formula for M?

a. M= LN/K
b. M=LNK
c. M=KL/N
d. M=K/LN


Solve this inequality: 3q + 11 + 8q > 99

a. q >11
b. q > 1/8
c. q > 88
d. q > 8

Thanks..

Answer 1

The first one is D I think. I'm not sure

The second one is D because you have to add 3q and 8q which is 11q. Then you have 11q + 11> 99. Now you subtract 11 from both sides and you'll get 11q>88. Finally you divide 11 from both sides and you get q>8.

HaHa hope this helps!!!!

Answer 2

K/L=MN
=> K/(LN)=M

Answer (d)

3q+8q>(99-11)
=>11q>88
=>q>88/11
=>q>8

Answer (d)

Answer 3

1. To solve for M we will need to get it by itself. To do that we put the L and N so that they will cancel out. You can do anything to an equation and keep it equal so long as you do the same thing to both sides.
k = LMN
k/LN = LMN/LN
Any number over itself is 1, and the 1 in 1M is understood so we don't need to write it.
k/LN=M or M=k/LN

2.
3q + 11 + 8q > 99
First we add like terms.

11q + 11 > 99
Then we need to get 11q by itself so we subtract 11 from both sides.
11q > 88
Divide by 11 to get q by itself.
q > 8

Answer 4

Q1)

You have been given:

k=LMN

Divide both sides by LN, you have;

k/(LN)=(LMN)/(LN)

thus; you have;

k/LN = M ;

or; M = k/LN

the answer is d;


Q2)

3q+11+8q>99;

or; 11q+11>99;


subtracting 11 from both side we have;

11q+11-11>99-11;

11q>88;

dividing both sides by 11; we have;

(11q)/11 > 88/11;

or; q > 8 ;

thus your answer is d.

Answer 5

b for the first i'm guessing but for the second one q>8 because if q is less than 8 then it is 7 so 3x7=21, 21+11=32 and 8x7=56 and 56+32=88

Answer 6

ans for 1st Q is option d. also option d for Q2nd

Answer 7

answers are d and d

Answer 8

d. and d.
