# Five times a number is the same as 30 more than 8 times the number. Find the number. If n is "the number," which equation could be used to solve for the number? 3n = 30 5n + 8n = 30 5n = 8n + 30

QUESTION POSTED AT 18/01/2020 - 06:39 AM

(C) Step-by-step explanation:  Given that five times a number is the same as 30 more than 8 times the number.

We are to find the number.

Also, if the number is denoted by n, then we are to select the equation that could be used to solve for the number.

Since n is the given number, so five times the number is written as Also, 30 more than eight times the number is written as Since both the expressions are same, so we get Thus, the required number is -10 and the the equation that is used to solve for the number is Option (C) is CORRECT.

None One Two Infinitely many Answer: Option (d) is correct. The equation 5x + 3(x − 1) = 10x − 2x − 3 will have infinite many solution. Step-by-step explanation: Given : the equation 5x + 3(x − 1) = 10x − 2x − 3 We have to find the number of solution to the equation 5x + 3(x − 1) = 10x − 2x − 3 Consider the given equation 5x + 3(x − 1) = 10x − 2x − 3 This can be written as two equations as y=5x + 3(x-1) .........(1) and y = 10x − 2x − 3 ......(2) Simplify, both the equations, y=5x + 3x - 3 = 8x - 3 and y = 10x − 2x − 3 = 8x -3 Since, both equations are same. So, the graph of both equation will overlap each other. Hence, the equation 5x + 3(x − 1) = 10x − 2x − 3 will have infinite many solution.

The answer to this question would be: Jim =6 years Harry =2 years To answer this question, you need to translate the description into a mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this: 1. H+4= J 2. (J+2)= 2(H+2) J+2= 2H+4 J= 2H +2 If you put the 1st and 2nd equation together, the result would be: H+4= J H+4= (2H +2) H-2H= 2-4 -H= -2 H=2 After that insert the H value to either 1st or 2nd equation.

### Nine less than twice a number is thirty one Step-by-step explanation:

Less than- you had to subtract by the minus sign.

First you had to translate words into an equation.

2x-9=31

Then you solve by equation and add by nine from both sides of equation form.  Next, you divide by two from both sides of equation form.      Hope this helps!
