Group like terms.
[tex]19a - 19a + 44[/tex]
Add similar elements.
[tex]19a - 19a = 0[/tex]
[tex]=44[/tex]
Answer:
44
Step-by-step explanation:
Hahaha, fair enough.
This one may look more difficult than it is. In algebra, there are variables and there are constants.
A constant is a number that is constantly the same, in the example you posted, 44 is the constant.
A variable is like a place holder, it indicates that there is a number that will be substituted in, we just don't know what that number is yet. In your example, the variable is represented by the letter "a."
If youre still a little unsure what a variable is, think of it like this:
Every morning, you like to have one, single cup of coffee, but some days you feel like putting 1 spoon of sugar in, some mornings you want no sugar, and some mornings you really want something sweet and so you have 3 spoons of sugar.
In algebra, your morning cup of coffee is represented 1 + s. 1 is the number of cups of coffee you have and "s" represents how much sugar you put in it. "s" can equal 1, 3, or even 0 spoons of sugar. "s" will represent the number of spoons of sugar consistantly, BUT, keep in mind that while the value of a variable is the same within that one term or equation it can represent a different value in another term or equation.
1 + s on Monday could equal 4 because you really want some sugar at the beginning of your week so you put 3 sugars in. 1 + 3 = 4. But on Thursday, you don't want any sugar, so 1 + 0 = 1. Monday and Thursday are different terms/equations.
SO, because a variable always has the same value within a term/equation, in your example 19a + 44 - 19a, "a" will always have the same value. if a = 1 then your example is 19(1) + 44 - 19(1). If the value of "a" is 1,000,000, then your example looks like 19(1,000,000) + 44 - 19(1,000,000).
We can rewrite your question a little to make it clearer. 19a - 19a + 44, we just swapped the positions of 44 and -19a. So you can see, that no matter what value "a" represents, they will cancel each other out. leaving you with 44 as your answer.

I bought a used grain silo. I am going to use it as a groom's room at our venue. I am going to paint the inside of it to brighten it up a little. I need to decide how many cans of paint to buy. The silo is 15' across and 10' tall to the top of the cylindrical part. The top of the silo looks like a funnel. It is also 15' across. It is 4' tall. The ceiling is the funnel top. A can of paint covers approximately 400 sq ft. How many cans of paint will I need to buy? Number only. Do not label.
(Don't worry about subtracting area of the door or windows. I'm okay with having a little extra paint. I can use it for touch ups.)
Answer:
approximately 2 cans
Step-by-step explanation:
total surface area of cylinder with one circular surface plus surface area of a funnel
(206.25+63.25) pie squared feets
270pie squared feets
number of cans = total surface area of figure divided by area covered per can
n= 270pie squared feets ÷400 squared feets
n= 2.121 cans
approximately 2 cans of paint
Dany bought a total of 20 game cards some of which cost $0.25 each and some of which cost $0.15 each. If Dany spent $4.2 to buy these cards, how many cards of each type did he buy?
Answer:
He bought 12 $0.25 costing cards and 8 $0.15 costing cards.
Step-by-step explanation:
Let the number of $0.25 costing cards he bought be s,
Let the number of $0.15 costing cards he bought be t,
According to the question,
He bought a total of 20 game cards,
Thus,
s + t = 20
or, s = 20 - t ------(i)
Now,
Since, he bought s and t no of cards each and it amounted to $4.2, we know,
$0.25s + $0.15t = $4.2
or, $0.25(20 - t) + $0.15t = $4.2 [From (i)]
or, $5 - $0.25t + $0.15t = $4.2
or, $5 - $4.2 = $0.1t
or, $0.8/$0.1 = t
t = 8
From (i),
s = 20 - t = 20 - 8 = 12
Therefore, he bought 12 $0.25 costing cards and 8 $0.15 costing cards.

Answer:
84in²Step-by-step explanation:
If the first one is 7 inches long, and 6 inches wide, and the second one is also 7 inches long, but is 6x2 inches wide, then what's the area?
6x2=12
So, Picture Frame 2 = 12 inches wide
Formula for finding area = LxW
L = 7
W = 12
7x12=84
So hence, your answer is 84in²
The area of the second frame is 84in²

sin (9x-7) = cos (4x-10) what is x
Answer:
sin(9x-8) = cos(4x+7)
sin(9x-8) = sin(90-(4x+7))

Step-by-step explanation:
A pediatric client with a ventricular septal defect repair is placed on a maintenance dose of digoxin. The safe dose is 0. 03 mg/kg/day, and the client's weight is 7. 2 kg. The primary health care provider (PHCP) prescribes the digoxin to be given twice daily. How much digoxin should the nurse administer to the client at each dose?
Using proportions, it is found that the nurse should administer 0.108 mg of digoxin to the client in each dose.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the daily amount is of 0. 03 mg/kg, hence for a person of 7.2 kg, the amount is:
T = 0.03 x 7.2 = 0.216 mg.
This daily amount is given in two equal doses, hence the amount of each dose is given by:
E = 0.216/2 = 0.108 mg.

Noah mows 1/2 of his property and leaves the rest wild. He decides to use 1/5 of the weld area for a vegetable garden. What fraction of the property is used for the garden ?
Solving the Question
We're given:
[tex]\dfrac{1}{2}[/tex] of the property was mowed[tex]\dfrac{1}{5}[/tex] of the unmowed property was used for a vegetable gardenWe must first find how much of the property was unmowed.
If [tex]\dfrac{1}{2}[/tex] of the property was mowed, then that leaves [tex]\dfrac{1}{2}[/tex] of the property unmowed.
⇒ [tex]1-\dfrac{1}2}=\dfrac{1}2[/tex]Now, we can find the fraction of the property used for the garden.
[tex]\dfrac{1}5}[/tex] of the [tex]\dfrac{1}2[/tex] of the property was used for the garden. To find this as a fraction, multiply [tex]\dfrac{1}5}[/tex] by [tex]\dfrac{1}2[/tex]:
[tex]\dfrac{1}5*\dfrac{1}2=\dfrac{1}{10}[/tex]
AnswerTherefore, [tex]\dfrac{1}{10}[/tex] of the property was used for the garden.

The common ratio of the geometric progression is r = 2
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the geometric progression be represented as A
Now , the value of A is
A = 2, 4, 8, 16, 32, 64, ...
Now , the common ratio r = second term / first term
On simplifying , we get
r = 4 / 2
r = 2
Hence , the common term of GP is r = 2
