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,
(2a - 13) ÷ b/15
The value of (2a - 13) ÷ b/15 when a = -2/5 and b = -8.25.
= (2a - 13) ÷ b/15
= (2 x (-2/5) - 13) ÷ -8.25 / 15
= (-4/5 - 13 ) ÷ -8.25 / 15
= (-4 - 65) / 5 ÷ -8.25 / 15
= -69/5 ÷ -8.25/15
= -69/5 x -15/8.25
= 69 x 3 / 8.25
= 207 / 8.25
= 20700/825
We will write this in a mixed fraction.
= [tex]25\frac{75}{825}[/tex]
Thus,
The value of (2a - 13) ÷ b/15 when a = -2/5 and b = -8.25 is [tex]25\frac{75}{825}[/tex]

A hamburger costs twice as much as a hot dog. Three hamburgers and two hot
dogs cost $21. Choose the system of linear equations that represents this problem.
A. 2y=x
2x+3y=21
B. y=2x
2x+3y=21
C.x=2y
3x+2y=21
D.y=2x
3x+2y=21
Answer:
C
Step-by-step explanation:
Hamburger = Hotdog x 2
3(Hamburger) + 2(Hotdog) = 21
Now replace with x (Hotdog) and y (Hamburger)
y = 2x
3y + 2x = 21

is this graph skewed or roughly symmetrical?
Answer: Roughly Symmetrical
Step-by-step explanation: There's no super easy way to explain why other than learning with experience but if you look at about the center of the graph, there are two peaks, and each side of the graph if split at about 68 which is the center, has 7 points each. This in conjunction with the shape and relatively normal spread makes it roughly symmetrical, not quire symmetrical but getting there.

Answer:
a) 5
b) 9
Step-by-step explanation:
The lines by the side decide absolute value, meaning distance from zero. for question A, simply add the integers to get -5. With the absolute value lines surrounding the question, you must make the answer 5 instead of -5 to show the distance from zero. In easier words, absolute value is just the positive number of an integer. For question B, the absolute value is surrounding just the -7, making it a positive 7. So, you simply just add 7 + 2 for question B, getting 9.

of <5 and <6.
122°

6
M<5 =
m<6=
Answer:
∠ 5 = 122° , ∠ 6 = 58°
Step-by-step explanation:
∠ 5 and 122° are vertically opposite and are congruent , then
∠ 5 = 122°
∠ 5 and ∠ 6 are same- side interior angles and sum to 180°
∠ 5 + ∠ 6 = 180° , that is
122° + ∠ 6 = 180° ( subtract 122° from both sides )
∠ 6 = 58°

Looking for the answer for the second one
Answer:
3 for the left one, and 5 on the right one.
Step-by-step explanation:
The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)
If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.
If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.

Answer:
53, 13, 3, -7
Step-by-step explanation:
When x = -5,
y = -10(-5) + 3

= 53
When x = -1,
y = -10(-1) + 3
= -10 + 3
= 13
When x = 0,
y = 3
When x = 1,
y = -10(1) + 3
