.For two matrices (a 3)=(-4 3), what is the value of a?
Answer:
-4
Step-by-step explanation:
[tex]\begin{pmatrix}a&3\end{pmatrix}=\begin{pmatrix}-4&3\end{pmatrix}[/tex]
If the second term is equal, 3 = 3 and the whole matrices are equal,
that means the first terms are equal.
Hence, [tex]a=-4[/tex]

Madeline borrow some money for my friends in order to help my name video game system. Mellana Green payback for friends five dollars per week and after 13 weeks Madeline still owed her friend five dollars. Right in equation for L in terms of t, representing them out Madeline I was her friend after T weeks
Answer:
L= -5t+70
Step-by-step explanation:
The equation that represents the total amount of L is
L - 5T = 5
Where T is the number of weeks.
The total amount was $80.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Madeline borrows some money from my friends in order to help my name video game system.
Mellana Green payback for friends five dollars per week and after 13 weeks Madeline still owed her friend five dollars.
Let the amount borrowed = L
Let the number of weeks = t
Now,
The equation that represents the above situation is:
L - 5T = 5
We see that,
After 15 weeks, t = 15.
L - 5 x 15 = 5
L - 75 = 5
L = 5 + 75
L = $80
The total amount borrowed was $80.
Thus,
The equation that represents the total amount of L is
L - 5T = 5
Where T is the number of weeks.
The total amount was $80.

Answer:
The value of k is 1.
Step-by-step explanation:
You have to apply Indices Law :
[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]
For this question :
[tex] {( \frac{4}{5} )}^{2} \times {( \frac{4}{5} )}^{5} = {( \frac{4}{5} )}^{6k + 1} [/tex]
[tex] {( \frac{4}{5}) }^{2 + 5} = {( \frac{4}{5}) }^{6k + 1} [/tex]
[tex]by \: comparison[/tex]
[tex]2 + 5 = 6k + 1[/tex]
[tex]7 = 6k + 1[/tex]
[tex]7 - 1 = 6k[/tex]
[tex]6k = 6[/tex]
[tex]k = 6 \div 6[/tex]
[tex]k = 1[/tex]
Answer:
k = 1
Step-by-step explanation:
[tex]a^{m} * a^{n} = a^{m+n}\\\\(\frac{4}{5})^{2}*(\frac{4}{5})^{5}=(\frac{4}{5})^{6k+1}\\\\\\(\frac{4}{5})^{2+5}=(\frac{4}{5})^{6k+1}\\\\(\frac{4}{5})^{7}=(\frac{4}{5})^{6k+1}[/tex]
Compare the powers,
6k + 1 = 7 {subtract 1 from both sides}
6k = 7 - 1
6k = 6 {Divide both sides by 6}
6k/6= 6/6
k = 1

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
The area will be calculated as,
Area = 2¹/₄ x 2³/₄
Area = ( 9 / 4 ) x ( 11 / 4 )
Area = 99 / 16
Enlarged by factor 7.
Area = (99 x 7 ) / 16
Area = 43⁵/₁₆

If BC = 61 and AB = 82, what is the length of AC?
Answer:
54.8
Step-by-step explanation:
Pythagorean theorem is a^2+b^2=c^2.
Plug the given values in to get 61^2+b^2=82^2
61^2 is 3,721 and 82^2 is 6,724.
6,724-3,721 is 3,003.
The square root of 3,003, rounded to a reasonable value, is 54.8.

a policeman and atheif are equidistant from the jewel bo upon considering jewel box as origin the position of policeman is(0,5).if the ordinate of the position of the theif is zero thn write the coordinates of the position of the theif
Answer:
(-5, 0) or (5, 0)Step-by-step explanation:
Coordinates given:
Policeman = (0, 5)Box with jewel = (0, 0)Thief = (x, 0)The distance from the policeman to the box with jewel is:
5- 0 = 5 unitsThe distance from the jewel box to the thief is also 5 units as they are both are equidistant from the jewel box
The x- coordinate is:
|x| = 5 ⇒ x = ± 5- 5 or 5 as it gives the same distance of 5 unitsSo his coordinates are (-5, 0) or (5, 0)

Step-by-step explanation:
The inequality is 1.20$ x + 3.60 < 9.60, the amount of money in total that Rammy has. As said, for each pound of peaches it would cost 1 dollar and 20 cents (1.20) So for the gallon of milk if Rammy bought it he would have 6$ left to spend on the pounds of peaches. So you do 6$ (600) divided by 1.20$ (120) and you would get 5 pounds of peaches. Therefore, Rammy can buy 5 or more pounds of peaches.

Jayana is trying to run a certain number of miles by the end of the month. If Jayana is 30% of the way to achieving her goal and she has already ran 9 miles, how many miles is she trying to run by the end of the month?
Answer: 30 miles
Step-by-step explanation: so first if Jayana is 30% of the way to achieving her goal and she has already ran 9 miles. You will have to convert 30% into a decimal. 30% is the same thing as 0.3 so, as that being said you will have to divide 9 by 0.3 because we are trying to find the miles.
