Solving a linear equation, we can see that each box has 15 jars.
Which equation can be used to find the number of jars in each box?
We know that Neve has 12 full boxes of jars of slime, and 7 jars of slime, then if each box has N jars, the total number of jars that Neve has is given by the linear equation:
12*N + 7
Now we know that Neve has 187 jars in total, then we can write:
12*N + 7 = 187
We want to find the value of N, which is the number of jars in each box, so we need to solve the linear equation:
12*N + 7 = 187
12*N = 187 - 7
12*N = 180
N = 180/12 = 15
We conclude that there are 15 jars in each full box.

A customer wants to buy 0.3 pounds of mulch that cost $7.30 per pound. if the customer has a coupon for $0.50 off the total cost, how much will they pay for the mulch?
Answer: The customer will pay 1.69$ for the mulch.
Step-by-step explanation:
7.30 = 1 Pound
0.3 = 3/10
3/10 x 7.30 or 3/10 of 7.30 = 2.19
2.19
2.19 = without coupon
1.69 = with coupon.
The total with 50 cents off is 1.69$.
Write the slope-intercept equation of a line that passes through the points (-2,5) and (6,-4)
The slope-intercept equation of a line that passes through the points (-2,5) and (6,-4) is [tex]y=-\frac{9}{8}x+\frac{11}{4}[/tex]
We know that the slope-intercept form of the line is y = mx + c, where m is the slope of the line and c is the y-intercept of the line.
For given question we have been given two points (-2,5) and (6,-4)
We need to find the slope-intercept equation of a line that passes through the points (-2,5) and (6,-4).
Using two-point form the equation of the line is,
[tex]\frac{y-y_1}{y_2-y_1}=\frac{x-x_1}{x_2-x_1}[/tex]
Let (x1, y1) = (-2,5) and (x2, y2) = (6,-4)
So, the equation of the line is,
[tex]\frac{y-5}{-4-5} =\frac{x-(-2)}{6-(-2)}\\\\ \frac{y-5}{-9} =\frac{x+2}{6+2}\\\\\frac{y-5}{-9} =\frac{x+2}{8}\\\\ 8(y-5)=-9(x+2)\\\\8y-40=-9x-18\\\\8y=-9x-18+40\\\\8y=-9x+22\\\\y=-\frac{9}{8}x+\frac{11}{4}[/tex]
above equation is in the slope-intercept form.
Therefore, the slope-intercept equation of a line that passes through the points (-2,5) and (6,-4) is [tex]y=-\frac{9}{8}x+\frac{11}{4}[/tex]

The sum of 2 integers is 7 and the sum of their squares is 37 what is the integers
Answer:
[tex]1[/tex] and [tex]6[/tex].
Step-by-step explanation:
Let [tex]x[/tex] denote one of the integers. Since the two integers add up to [tex]7[/tex], the other integer would be [tex](7 - x)[/tex].
The sum of the squares of these integers is [tex]37[/tex]. In other words:
[tex]x^{2} + (7 - x)^{2} = 37[/tex].
Expand [tex](7 - x)^{2}[/tex] using binomial expansion. Simplify and rewrite this equation and solve for [tex]x[/tex].
[tex]2\, x^{2} - 14\, x + 12 = 0[/tex].
[tex]x^{2} - 7\, x + 6 = 0[/tex].
Using the quadratic formula or factorization, [tex]x = 1[/tex] or [tex]x = 6[/tex]. Thus, the two integers are [tex]1[/tex] and [tex]6[/tex].
a test shows that 10 out of 100 gadgets are defective. in a random sample of two gadgets are chosen the probability that both are defective is
The probability of selecting both defective gadgets out of 100 gadgets is 1/110, which is calculated using the basic concepts of probability theory.
What is a random experiment?
An experiment that is repeated several times and produces more than one possible outcome is called as the random experiment. It contains a well-defined set of values which constitutes a sample space. Eg: Rolling a die, tossing a coin etc.
Calculation of the probability of selecting both gadgets as defective
The total amount of gadgets = 100
Number of defective gadgets = 10
The probability of selecting a defective gadget is 10 / 100 or 1 / 10
Now, the total number of gadgets and defective gadgets are decreased by 1
So, the probability of selecting another gadget as defective is 9 / 99 or 1 / 11
P(E) = P(when two selected gadgets are defective) = 1 / 10 x 1 / 11
P(E) = 1 / 110
Hence, the probability of selecting both defective gadgets is 1/110.

37 centimeters is the same as how many inches? Hint: 1 cm ≈ 0.39 in Round your answer to the nearest tenth. HELP PLEASE!!!
37 centimeters is equal to approximately 14.5 inches.
In both the British imperial and American customary systems of measurement, the inch serves as a unit of length. It is equal to 1/12 of a foot or 336 yards.The International System of Units (SI) uses centi as the prefix for a factor of 1/100, making a centimeter (international spelling) or centimeter (American spelling) (SI symbol cm) equivalent to one tenth of a meter. In the now-outdated centimeter-gram-second (CGS) system of units, the centimeter served as the fundamental unit of length.We know that 1 cm is equal to 0.39 inches.
So to convert 37 cm to inches we multiply 37 with 0.39
37×0.39=14.47 inches

a) Gas has a volume of 12 liters.
b) 12 liters of oxygen gas will be consumed during the reaction.
Step-by-step explanation:
Moles of Substances:
We measure the quantity of atoms and molecules in moles, which is equal to 6.022 ×10²³, Avogadro's number, because they are too small to be counted or weighed individually. A substance's atomic mass is multiplied by Avogadro's number to get its mass in grams.
Here, Half a mole of carbon is equal to six grams of carbon. since 12 grams make up one mole of carbon. Since carbon dioxide has the chemical formula CO2, when a mole of carbon is fully combusted, it will result in the production of a mole of carbon dioxide gas.
a) Half a mole of gas has a volume of 12 liters because one mole of gas at RTP consumes 24 liters.
b) Due to the fact that each oxygen molecule contains two oxygen atoms and each carbon dioxide molecule contains two oxygen atoms, 12 liters of oxygen gas will be consumed during the reaction.

3 Answers: Choice A, Choice B, Choice E
=========================================================
Explanation:
We have four copies of x in the original expression. So that accounts for the 4x. In other words, 4x = x+x+x+x. Multiplication is used for repeated addition.
Also, the other terms add to 15+5+15+5 = 20+20 = 40
Therefore, we end up with 4x+40 from choice A.
-----------------------------
Once we get to 4x+40, we can factor out 2 from it like so
4x+40
2*2x + 2*20
2(2x+20) which is choice B
I used the distributive property to factor. That rule is a(b+c) = ab + ac
-------------------------------
Choice C is not one of the answers. We can determine this fairly quickly by noting that the expression in choice C talks about a quadratic, but the original expression given to us is linear.
Choice D is a similar story to choice C.
--------------------------------
Choice E is another answer

Isaac bought two DVD's and spent over 50 . Use indirect reasoning to show that at least one of the DVD's he purchased was over 25 .
By assuming that both DVD's cost $25 or less, we will reach an absurd. In that way we conclude that at least one of the two DVD's costs over $25.
How to use the indirect reasoning?
We know that Isaac bought two DVD's and spent over $50.
Let's define the variables:
x = cost of the DVD 1y = cost of the DVD 2Because the cost is over $50 we can write the inequality:
x + y > $50
Here we want to prove that at least one of the two DVD's costed over $25, now let's find an absurd here, let's assume that neither of the DVD's costed over $25, then we can write:
x ≤ $25
y ≤ $25
So we have a set of 3 inequalities:
x + y > $50
x ≤ $25
y ≤ $25
Now, the maximum values that x and y can take are $25, if we use these values in the first inequality we will get:
$25 + $25 > $50
$50 > $50
So this is an absurd, this means that we can't assume that neither of the DVD's costs over $25, then we conclude that at least one of the DVD's costs over $25, which is what we wanted to prove.
