**Answer: the correct option is **

**(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.**

The answer is Choice A 7 nickels and 18 dimes why? because the question tells you that There are 25 nickels and dimes worth $2.15. So 18 dimes that is worth $1.80 and 7 nickels that is worth $0.35 so you add $1.80 + $0.35 that = $2.15. So the answer again is Choice A 7 nickels and 18 dimes.

So we need f(4)

F(4)=(4)^3 -1

F(4)=64-1=63

Here a=4

So we need f(4)

F(4)=(4)^3 -1

F(4)=64-1=63

**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.**

Did your explanation include the following?

Some polynomial equations have complex solutions.

Therefore, complex solutions cannot be found by graphing the related system or function in the Cartesian (x-y) plane.

Polynomial functions with all complex solutions do not have x-intercepts, and the related system of equations will not intersect.

QUESTION POSTED AT 20/02/2020 - 11:19 PM

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.

H+4= J

2+4=J

J= 6

Jim =6 years

**Answer:**

**Required Equations are x + y = 24 & x - y = 6**

**Step-by-step explanation:**

let x be the no of yellow marbles that Charles has.

and y be the no of blue marbles that Charles has.

Total Marbles that Charles has = 24

**⇒ x + y = 24 ..............(1)**

Charles has 6 more yellow marbles than blue marbles.

**⇒ x = y + 6**

** x - y = 6 ......................(2)**

Therefore, **Required Equations are x + y = 24 & x - y = 6**
