Answer:
x=2
Step-by-step explanation:
Add 4 to both sides:
-2=-4+x
-2+4=-4+4+x
2=x
Answer:
[tex]x = 2[/tex]
Step-by-step explanation:
First we must add 4 to both sides.
[tex]-2 = -4 + x[/tex]
+4 +4
-4 + 4 = 0
-2 +4 = 2
Isolating a variable means that it is alone on its side of the eqation.
[tex]2 = x[/tex]
x is now isolated and we also have the solution for it.
[tex]x = 2[/tex]

Use Newton's Law of Cooling to find the temperature of a substance as a function of time t in minutes that it has spent
cooling off. This relationship is given by, y = ae* +, where c is the temperature of the medium surrounding the cooling
object, a is the difference between the initial temperature of the object and the surrounding temperature, and k is a
constant related to the cooling object. Two samples of the substance were heated in a container of boiling water until their
initial temperatures were both 100° C. The first sample will be cooled by being left out at a room temperature of 24°C,
and the second sample of the substance will instead be cooled off in a refrigerator with an inside temperature of 4° C.
The value of a will equal the difference between each sample's initial temperature and that sample's surrounding
temperature, and the cooling constant of the substance is k = 0.12.

A sporting goods store has a sale on soccer balls: if you buy two soccer balls at the regular price, you get a third soccer ball for $1. Coach John bought 24 identical soccer balls during this sale for $136. What is the regular price for one of these soccer balls?
Answer:
The regular price of the balls is $8
Step-by-step explanation:
The sporting goods store sales promotion is as follows;
The price of the third ball after buying two balls at regular price = $1.00
The price of the number of balls Coach John pays for the balls he bought = $136
To buy 24 balls, we have;
2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1
Therefore;
The number of balls bought at regular price = The sum of the 2s = 16 balls
The number of balls bought for $1 = 24 - 16 = 8 balls
Let x represent the regular price of the balls, we have;
16 × x + 8 = 136
16·x = 138 - 8 = 128
x = 128/16 = 8
The regular price of the balls = x = $8.
Simplify this algebraic expression completely.

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is
5
8
.
There are 56 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.
Answer:
35 red marbles
Step-by-step explanation:
since probability for red marbles is 5/8
and they are 56 marbles in the bag
so it will be 5/8 × 56
= 35
so the bag is likely to have 35 red marbles

What is the area of a triangle with a base of 4 inches and a height of 17 inches?
Answer:
Area of triangle = 34 in²
Step-by-step explanation:
Base = 4 inches
Height = 17 inches
[tex] \rm Area \: of \: triangle = \dfrac{1}{2} \times Base \times Height \\ \\ \rm = \dfrac{1}{2} \times 4 \times 17 \\ \\ \rm = 2 \times 17 \\ \\ \rm = 34 \: {in}^{2} [/tex]
Answer:
The required area of the ∆:
[tex] \boxed{ \rm{ar( \triangle) = 34 \: {inch.}^{2} }}[/tex]
Step-by-step explanation:
We have:
Base = 4 inchesHeight = 17 inchesBy using Formula, A = 1/2 * bh
⇒ ar(∆) = 1/2 × 4 × 17 inch²
⇒ ar(∆) = 2 × 17 inch²
⇒ ar(∆) = 34 inch²
Thus, The Area of Required ∆ is 34 inch²

OK SO I SOLVED ALL OF THIS: It costs a company $20 per box to make pocket-sized stuffed animals. The company also has a fixed manufacturing cost of $2300. The owners are trying to calculate their cost for making boxes of animals. --Function Rule: c(x) = 20b + 2300.
BUT I NEED HELP WITH THIS!!! Use your function rule to find out how many boxes of stuffed animals can the company manufacture for $5000? SHOW WORK.
basically just show the work to find out what "b" would have to be in order for the answer to be $5,000 i would appreciate it so much :) please help this is due today :(
Answer:
The company can manufacture 135 boxes of stuffed animals for $5000
Step-by-step explanation:
To find b, substitute $5000 for c(x), so
5000 = 20b + 2300Then subtract 2300 from both sides of the equation, so
5000 (-2300) = 20b + 2300 (-2300)2700 = 20bFinally divide both sides of the equation by 20, so
2700/20 = 20b/20135 = bTo check your answer substitute 135 in as b...
c(x) = 20(135) + 2300c(x) = 5000a. How much is 50% of 10 liters of milk?
