99
• Step-by-step explanation:
Hi there !
use formula a² - b² = (a-b)(a+b)
18² - 15² =
= (18 - 15)(18 + 15)
= 3×33
= 99
Good luck !

You are planning a road trip and you are preparing the songs you will be listening on the Road. You start by downloading 5 songs for $7.50 on one day and 8 songs for $12 the following day.
How much do 2 songs cost?
Answer:
$3.00
Step-by-step explanation:
7.50/5 = 1.5
12/8 = 1.5
Since each song costs $1.50 each, multiply the cost by the number of songs.
1.50(2) = 3
$3.00
In fig if x+y=w+z then prove that AOB is a line.
Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∘
∣ Angles around a point.
(x+y)+(w+z)=360
∘
(x+y)+(x+y)=360
∘
∣ Given x+y=w+z
2(x+y)=360
∘
(x+y)=180
∘
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line

Can somebody please tell me what 1 1/3+(−5/6) is??
1/2
Step-by-step explanation:Hi there !
1 1/3 + (-5/6) =
= (1*3+1)/3 - 5/6
= ²⁾4/3 - 5/6
= 8/6 - 5/6
= (8 - 5)/6
= 3/6
= 1/2

Rational numbers are all positive and negative numbers and can be written as a fraction.
4(x - b) = x
solve for x
Answer:
x=4b/3
Step-by-step explanation:
Simplify 4(x - b) = x
Then Move all terms containing x to the left side of the equation.
so -4b+3x=0
Add 4b to both sides of the equation.
so 3x=4b
Divide each term by 3 and simplify!
A 4-column table with 6 rows. Column 1 is labeled x with entries 1.5, 3, 5.5, 6.25, 7, Sigma-summation x almost-equals 23.25.
Column 2 is labeled y with entries 9.5, 17, 34.5, 31, 35, sigma-summation y almost-equals 127.
Column 3 is labeled x squared with entries 2.25, 9, 30.25, 39.06, 49, sigma-summation x squared almost-equals 129.56.
Column 4 is labeled x y with entries 14.25, 51, 189.75, 193.75, 245, sigma-summation x y almost-equals 693.75.

Can anyone explain what Literal Equations are? PLZ.
Answer:
A literal equation is an equation that consists of multiple variables or letters.
A linear equation is an equation that consists of one variable
Step-by-step explanation:
Literal EX:
a = 1/2h(a + b)
ax + b = c
u = ak/b
Linear EX:
5(3a + 8) = 12a
4a = 8
11(3a - 18) = 12a
Answer:
So A literal Equation is practically made up of all letters ( also known as variables) So to answer one you have to try an isolate the variable for example * ax + b = c * You want to isolate * x *. You aren't trying to solve for x like you would for any other equation. You then have to do inverse operations. Below I have added a screenshot picture because I have done an example for you so that you can better understand what I'm explaining. I hope this helps you! :)

please help me ill give brainiest to whoever is right i need help asap
Answer:
73 degrees
Step-by-step explanation:
So first, since there are two lines that are parallel, and there is a transversal, angle a and angle b are supplementary due to same side interior angles.
Next, we make an equation: 6x-35+3x+53=180, and after that you come up with 9x+18=180. Put the numbers on one side and the variables on one side, and since you put 18 on the other side, you have to change it to -18. 180-18= 162.
9x=162. In conclusion, x=18. And to find angle a, plug x in. Therefore, the final answer is 73 degrees
