Answer:
x = 12
Step-by-step explanation:
[tex]90 + 3x + 16 + 2x + 14 = 180 [/tex]
[tex]5x + 120 = 180[/tex]
[tex]5x = 180 - 120[/tex]
[tex]5x = 60[/tex]
[tex]x = \frac{60}{5} = 12[/tex]
Answer:
x = 12°
Step-by-step explanation:
[tex](3x + 16) + 90 + (2x + 14) = 180 \\ 3x + 2x = 180 - 16 - 90 - 14 \\ 5x = 60 \\ x = \frac{60}{5} \\ x = 12[/tex]

Step-by-step explanation:
The formula you would use is: A = P(1 + rt)
P is the principal which is $270
r is the interest rate
t is the time in years but we have 11 days so 11/360
A is $19.8
let's put the values in the formula
$289.9= $270(1 + r*(11/360))
you will find the r is 2.4

Alia has a AED 20 gift card for an online music store. All songs at the store have the same price. After Alia buys 3 songs, the balance on the card is AED 16.25. What will be the remaining balance on the card after he buys 5 more songs
Answers
Answer:
Remaining balance = AED 13.75
Step-by-step explanation:
Given that:
Amount of gift card = AED 20
Amount left after buying 3 songs = AED 16.25
Cost of 3 songs = 20 - 16.25 = AED 3.75
Cost per song = [tex]\frac{3.75}{3}[/tex]
Cost per song = AED 1.25
Cost of 5 songs = 5(1.25) = AED 6.25
Remaining balance = 20 - 6.25 = AED 13.75
Hence,
Remaining balance = AED 13.75

if AB=BA= I then write the relation between matrix A and matrix B
Answers
Answer:
If AB = BA = I, then B is inverse of A and vice-versa.
Step-by-step explanation:
Given: AB = BA = I
To find: The relation between matrix A and B.
If AB = BA = I, then B is called the inverse matrix of A and is denoted by [tex]A^{-1}[/tex].
In that case, A is said to be invertible.
Also, if B is the inverse of A, then A is also the inverse of B.
Hence, the relation between A and B is that both are inverse of each other.

Answer:
(x, y) = (1, 8)
Step-by-step explanation:
A graphing calculator quickly tells you the point of intersection.
__
You can equate the y-values and solve for x.
3x +5 = -2x +10
5x = 5 . . . . . . . . . add 2x-5
x = 1 . . . . . . . divide by 5
3·1 +5 = y = 8 . . . . substitute for x in the first equation
The point of intersection is (x, y) = (1, 8).

The two angles are supplementary angles and when added together equal 180 degrees.
3x -12 + x+2 = 180

4x -10 = 180
Add 10 to both sides
4x = 190
Divide both sides by 4
X = 190/4

Answer:. 151/99
Step-by-step explanation:
Take the repeating digits from the decimal equivalent, 52 and place them as the numerator of a fraction with 99 as the denominator. That is 52/99
We can verify this value by doing the long division, or enter the values as 52÷99 on a calculator.
For the improper fraction:
Convert the whole number, 1, to its equivalent, 99/99. ( If the whole number is other than 1, multiply it by the denominator and use the product as the numerator. )
Add the numerators: 52 + 99 = 151
Our improper fraction equivalent of 1.525252 is 151/99
