-3x+3=-7x-1 and you solve for x
Answers
Answer:x=-1
add 1 to 3 to get 4, add 3 to -7 to get -4, divide both sides by -4
Answer:
-1[tex] \: [/tex]
Step-by-step explanation:
Given Equation,
[tex] \\ {\longrightarrow \qquad{ \sf{-3x+3=-7x-1}}}\\ \\ [/tex]
Adding 7x to both sides we get,
[tex]{\longrightarrow \qquad{ \sf{-3x+3 + 7x=-7x-1 + 7x}}}\\ \\ [/tex]
[tex]{\longrightarrow \qquad{ \sf{4x+3=-1}}}\\ \\ [/tex]
Subracting -3 from sides we get,
[tex] \\ {\longrightarrow \qquad{ \sf{4x+3 - 3=-1 - 3}}}\\ \\ [/tex]
[tex]{\longrightarrow \qquad{ \sf{4x=-4}}}\\ \\ [/tex]
Dividing both sides by 4 we get,

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

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?
Answers
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.

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

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?
Answers
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.

The GCD and LCM of three numbers are 3 and 1008 respectively.If two of the numbers are 48 and 72.Find the least possible value of the third number
Answers
Answer:
21
Step-by-step explanation:
We decompose prime factors of 48, 72, and 1008
48=2*2*2*2*3
72=2*2*2*3*3
1008=2*2*2*2*3*3*7
Let's compare 48, 72 with GOD(3) and LCM(1008), we can find that there must be at least 2 prime factors in the third number that is 3 and 7.
And let's find out the LCM of 48 and 72. Quite obvious the answer is 144.
Since the LCM should be the consequence of 144 multiplied by another prime factor.
Then let's try 144*7. Amazingly 144*7=1008. DONE!
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.
