The equation that has infinitely many solutions is A. 4x + 5(2x + 6) = 14x + 30
How to determine the equation?An equation with infinitely many solutions is represented as:
ax + b = ax + b
This means that both sides of the equation must be the same.
Next, we test the options:
4x + 5(2x + 6) = 14x + 30
Open the bracket
4x + 10x + 30 = 14x + 30
Evaluate the like terms
14x + 30 = 14x + 30
Both sides of the equation must be the same.
Hence, the equation that has infinitely many solutions is A. 4x + 5(2x + 6) = 14x + 30

The solution matrices shown are the result of reducing the augmented coefficient matrix to "reduced row-echelon form". Many calculators and spreadsheets have functions specifically for that purpose.
The attachment shows the result of a TI-84 work-alike calculator's reduction of the coefficient matrix. It matches the first choice.

Additional comment
When the equations are written in the form shown here, with the variables in the same order, and the constant on the right side of the equal sign, the augmented matrix is simply the matrix of the numbers. It is shown as the argument of the RREF function in the attachment.
The left-right order of the variables on the left side of the equal sign matches the top-down order of the solution values in the rightmost column of the reduced matrix. That is, ...

Wendy had 35 coins in pennies and nickels.She had $1.03.3Which system of equations could be used to determine the number of coins she has?
A..01p +.05n = 35 B. 1p +5n = 1.03
p+ n =1.03 p + n = 35
C .01p + .05 n = 1.03 D. .05p + .01n = 1.03
p + n = 35 p + n = 35
Answer: c. p+n=35, 0.01p+ 0.05n = 1.03
Step-by-step explanation: p= number of pennies, n = number of nickels. Given the total number of coins is 35, we have the equation p+n = 35.
She has total of $1.03. The equation for that would be 0.01p + 0.05n = 1.03

Alex's favorite number is 175% of Winnie's favorite number. Winnie's favorite number is 48 less than Alex's favorite number. What is Winnie's favorite number?
Answer:
64
Step-by-step explanation:
The information can be written as:
Let Alex's number = x
Winnie's number = y
x = 1.75y
x = y + 48
Substitute 1.75y for x:
1.75y = y +48
0.75 y = 48
3/4 y = 48
y = 64
Winnie's favourite number = 64.

Three solid shapes a, b and c are similar.
the volume of shape a is 27 cm
the volume of shape b is 64 cm
the ratio of the surface area of shape b to the surface area of shape c is 8:15
work out the ratio of the height of shape a to the height of shape c.
The ratio of the height of shape A to the height of shape C is [tex]\frac{3}{10}[/tex]
Calculations and Parameters:First step:Recall that similar figures have the same scale factor squared due to the ratio of its surface area.
Hence,
We would make:
z-----> the scale factorx----> surface area shape Ay----> surface area shape B[tex]z^2 = x/y\\z= 2/5[/tex]
Therefore, the ratio of the height of shape A to the height of shape B is = [tex]\frac{hA}{hB} = \frac{2}{5}[/tex]
Next step:To find the ratio of the height of shape B to the height of shape C, we would perform a similar operation which is:
[tex]z^3 = 27/64\\z= 3/4[/tex]
The ratio is:
[tex]\frac{hB}{hC} = \frac{3}{4}[/tex]
Final step:To find the ratio of the height of shape A to the height of shape C would be:
[tex](\frac{hA}{hB}) (\frac{hB}{hC} )= \frac{hA}{hC}[/tex]

Only three are geometric sequences, a which is 3/16, 3/8, 3/4, 3/2, d which is 3,9,27,81 and f which is -4(4/9)^x
What is a geometric sequence?A geometric sequence is a sequence of numbers or functions in which successive member differ by a constant term called the common ratio.
Analysis:
For a, the first term is 3/16, second term is 3/8. if we divide the second term by the first we have 2. If we do same with the third and second we still have 2. so this is a geometric sequence
For d, if we divide 9 by 3 we have 3, if we divide 27 by 9 we have 3. so this is a geometric sequence.
For f, if we make x equal to a nonzero integer, we have first term as -16/9, second term as -64/81 and third term as -256/729. if we divide the second term by the first we have -4/9, if we divide the third by the second we have-4/9.

$75 before tax. Disc: 10% Tax: 7%, Tip: 20% what’s the total?
Answer:
$102.75
Step-by-step explanation:
Given the following question:
We are given a cost of 75 dollars and are being asked to find the total cost after adding a tip, tax, and disc to the cost. To find this answer we will use the formula to calculate percentages making sure we use 75 as our base for each addition to our total cost.
Formula to calculate percentages:
[tex]\frac{p\times n}{100}[/tex]
First the disc:
[tex]\frac{10\times 75}{100}[/tex]
[tex]10\times75=750[/tex]
[tex]750\div100=7.5[/tex]
[tex]=7.5[/tex]
Next the tax:
[tex]\frac{7\times75}{100}[/tex]
[tex]7\times75=525[/tex]
[tex]525\div100=5.25[/tex]
[tex]=5.25[/tex]
Last but not least the tip:
[tex]\frac{20\times75}{100}[/tex]
[tex]20\times75=1500[/tex]
[tex]1500\div100=15[/tex]
[tex]=15[/tex]
Finally add:
[tex]75+7.50+5.25+15=102.75[/tex]
[tex]=102.75[/tex]
The total cost after adding the disc, tax, and the tip will be "$102.75."
