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]

There are 6 triangles and 8 squares. What is the simplest ratio of triangles to total shapes?
Answer:
3:7
Step-by-step explanation:
The number of triangles is 6.
The number of squares is 8.
The total number of shapes is 14.
The unsimplified ratio of triangles to total shapes is 6:14.
The bigger number that both 6 and 14 can be divided by is 3.
That makes the ratio 3:7, and it cannot be simplified further.

9514 1404 393
Answer:
k = 2
Step-by-step explanation:
The slope formula gives the slope between two points:
m = (y2 -y1)/(x2 -x1)
-2 = (-2 -0)/(3 -k)
Multiplying by (3 -k) gives ...
-2(3 -k) = -2
3 -k = 1
k = 3 -1 = 2
The value of k is 2.

Answer:
Step-by-step explanation:
1) 6 and -5
x₁ + x₂ = 6 +(-5) = 1
x₁* x₂ = 6*(-5) = -30
x² -(x₁ + x₂)x + (x₁* x₂)=0
x² - x - 30 = 0
2) 4 and 7
x₁ + x₂ =4 + 7 = 11
x₁* x₂ = 4*7 = 28
x² - 11x + 28 = 0
3) 1 and -10
x₁ + x₂ = 1 +(-10) = -9
x₁* x₂ = 1*(-10) = -10
x² - 9x - 10 = 0
4) -9 and 0
x₁ + x₂ = -9 + 0 = -9
x₁* x₂ = 0
x² - (-9)x = 0
x² + 9x = 0
5)2 and 6
x₁ + x₂ = 2 + 6 = 8
x₁* x₂ = 2*6 = 12
x² -8x + 12 = 0
8) 2 +√3 and 2 - √3
x₁ + x₂ = 2+ √3 + 2 - √3 = 4
x₁* x₂ = (2 + √3)(2 - √3) = 2² - (√3)² 4 - 3 = 1
x² - 4x + 1 = 0

D
29
E
А
F
Answer:
a straight line has an angle of 180
therefore 180-109=71
71÷2 = 35.5
x is 35.5 degrees
The measure of x is 29 degree.
What is Parallel line?Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.As, Parallel line have property
Any two lines are considered to be parallel if the angles formed by them are equal.If the Opposite interior angles formed by two lines are equal, they are said to be parallel.If the Opposite exterior angles formed by two lines are equal, they are said to be parallel.If the Successive interior angles on the same side of the transversal are additional, two lines are said to be parallel.As, <CBA = <BAD (Alternate Interior Angle)
So, <BAD = 42
Now, <BAD + <BAC + <CAE = 180 (Linear Pair)
42 + 109 + x = 180
151 +x = 180
x = 180- 151
x = 29

Which glide reflection describes the mapping triangle ABC to triangle DEF?
3 boys share £99. John gets twice as much as Robert and three times as much as Edward. How much does Edward get?
Answer:
£18
Step-by-step explanation:
Ratio is 6:3:2
(john:robert:edward)
added together is 11, divide 99 by 11 to get 9, multiply the ratio numbers by 9
54:27:18
Check answers:
27 times 2 = 54 yes
18 times 3 = 54 yes
54 + 27 + 18 = 99 yes
Since it goes John : Robert : Edward (edward is last) and 54:27:18 (18 is last)
Edward got £18
Yesterday you borrowed $60 from your brother. Every day that you don't pay it back, you owe $2.00 more. So today, day one, you owe him $62.00, on day two you will owe him $64.00, on day three you will owe him $66.00, etc. If you still haven't paid him back, how much will you owe him on day 25?
Answer:
110 dollars.
Step-by-step explanation:
Since every day you owe him 2 dollars more, and its been 25 days, 25 x 2 is 50.
You originally owed him 60, and 50 dollars in late fees, so 60 + 50 = 110.
You owe him 110 dollars.
