Answer:

Number of wooden carving = a

Total amount Sam spend = 1,200 + 4a

Total revenue of Sam = 15a

Number of wooden carving make to earn profit $4,300 = 500 carvings

Step-by-step explanation:

Given:

Sales price of each wooden carving = $15

Fixed cost = $1,200

Variable cost = $4 for each

Find:

Number of wooden carving make to earn profit $4,300

Computation:

Part 1

Assume

Number of wooden carving = a

Part 2

Total amount Sam spend = 1,200 + 4a

Part 3

Total revenue of Sam = 15a

Part 4

Total profit of Sam = Total revenue of Sam - Total cost of Sam

4,300 = 15a - [1,200 + 4a]

4,300 = 15a - 1,200 - 4a

11a = 5,500

a = 5,500 / 11

Number of wooden carving make to earn profit $4,300 = 500 carvings

2. The following formula relates three quantities: Force (F), mass (m), and acceleration (a).
alexandr1967 [171]
Given:  F=ma.  To solve for a, we isolate a on one side of this equation.  To do this, divide both sides of F=ma by m.  Then F/m = a.

Thus, if m=10 units, the acceleration is a = F/10 units.  Looks as tho' you were given the numeric value of F but did not share that value here.  

Solving F=ma for m:  m=F/a.  Thus, if F=25 units and a=5 units, m=25/5 units, or m=5 units.

Let m = 6x + 5.
arsen [322]

We have been given that m=6x+5. We are asked to write (6x + 5)^2-10 =-18x-15 in terms of m.

First of all, we will factor -3 from right side of equation as:

(6x + 5)^2-10 =-3\cdot 6x-3\cdot 5

(6x + 5)^2-10 =-3( 6x+5)

Now we will substitute m=6x+5 in our equation as:

(m)^2-10 =-3(m)

m^2-10 =-3m

Upon adding 3m on both sides, we will get:

m^2+3m-10 =-3m+3m

m^2+3m-10 =0

Therefore, the equation m^2+3m-10 =0 is equivalent to (6x + 5)^2-10 =-18x-15 in terms of m.
