Consider the linear equation 2/5x+y=11. will you choose to fix x or y?

1 answer:

4 0

Y is the easiest to fix because it has no coefficient, and is therefore the easiest to set on the other side of the equation by itself

Which system of linear equations could be used to determine the price of each book

GuDViN [60]

Answer:

Let the price of the maths book be m and price of the novel book be n

Given that,

Total cost of the books is $54

The price of math book is $8 more than 3 times the price of novel book.

we get,

The system of equation as,

$\begin{gathered} m+n=54 \\ m=8+3n \end{gathered}$

Hence the system of equation to determine the price of the maths and novel book is,

$\begin{gathered} m+n=54 \\ m=8+3n \end{gathered}$

(50 points) Could someone help me with this? Part A: Solve –mk – 90 > 85 for m. Part B: Solve 3c – 5f = 55 for f. Show your w

PilotLPTM [1.2K]

-mk - 90 > 85

-mk - 90 + 90 > 85 + 90

-mk > 175

-mk / k > 175 / k

-m > 175/k

-m * -1 < 175/k * -1

m < -175/k

Part B:

3c - 5f = 55

3c - 5f - 3c = 55 - 3c

-5f = 55 - 3c

-5f/5 = (55 - 3c) / 5

-f = 55/5 - 3c/5
