148+x = 180
x = 180-148
x=32
The angle sum property of a triangle:

Which expression is the result of solving the equation ax-b=cy for x (For a[tex]\neq[/tex]0)
Answer:
x = (cy+b)/a
Step-by-step explanation:
ax-b=cy
Add b to each side
ax-b+b=cy+b
ax = cy +b
Divide each side by a
ax/a = (cy+b)/a
x = (cy+b)/a

Step-by-step explanation:
let the second number=x
the first number=3x-4
(x+3x-4)+5=25
4x-4+5=25
4x+1=25
4x=25-1
4x=24
x=6
Since x is the first number,the first number is 6
second number=3•6-4
=18-4=14

24x cm
The right-angled triangle in the diagram has sides of length 7x cm, 24x cm and 150 cm
a Show that x= 36.
9514 1404 393
Answer:
can't be done. x = 6, not 36
Step-by-step explanation:
Without the diagram we must speculate that the 150 cm length is the hypotenuse. Then we have ...
150² = (7x)² +(24x)² = (49 +576)x² = 625x² . . . . Pythagorean relation
150²/625 = x² = 36 . . . . . divide by 625
x = √36 . . . . . . . . . . . take the square root
x = 6
ESSENTIAL QUESTION How do graphs
and equations reveal information about a
relationship between two quantities?
Answer:
When you plot the graph, you may see a line or a curve. This presents the trend of the relationship of the two quantities when the independent variable changes.
Graphs visually depict patterns and trends, while equations provide precise mathematical descriptions, both revealing valuable information about the relationship between two quantities.
Graphs visually represent data and patterns, allowing us to identify the nature of the relationship between two quantities. The slope and intercepts of a graph provide information about the rate of change and the values when one quantity is zero.
Equations, on the other hand, offer precise mathematical descriptions of the relationship. The form of the equation reveals the nature of the relationship, while coefficients and constants provide specific information. Solving equations yields solutions that satisfy the relationship.
Both graphs and equations work together to provide a comprehensive understanding of the relationship between two quantities, with graphs offering visual insights and equations providing precise mathematical information.

Durning Saturday’s thunderstorms a total of 500 mm of rain fell in fell in 20 minutes.How many mm fell per minute
Answer
25mm of rain fell each second
Step-by-step explanation:
we know that 500 mm fell in 20 minutes
so, we have to divide 500 by 20 giving us the amount of rain that fell each minute:
500/20 = 25
therefore, 25mm of rain fell each minute
hope this helped:)
Answer:
25 mm per minute
Step-by-step explanation:
Take the amount of rain and divide by the number of minutes
500/20
25 mm per minute

find the missing side of the triangle
Answer:
7 sqrt(2) = c
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
7^2 + 7^2 = x^2
49+49 = c^2
98 = c^2
Taking the square root of each side
sqrt(98) = sqrt(c^2)
sqrt(49*2) = c
7 sqrt(2) = c

A. 4x-3
B. 2x - 3
C. -18x - 17

Answer:
B
Step-by-step explanation:
-10 + 3x - x - 7x + 5x + 7 + 2x
combine like terms
-10 + 3x - x - 7x + 5x + 7 + 2x
-3 + 3x - x - 7x + 5x + 2x
the -7x and the 5x + 2x cancel out to 0, so for the x terms we are left with 3x -x to get 2x
= 2x - 3

Amazon is sold at rupees 99000 after 10% discount and 10% bat on the Marked price find the discount amount and vat amount
Answer:
Here,
SP with VAT = Rs. 99000
Discount = 10%
VAT = 10%
Discount Amount =?
VAT Amount = ?
We know,
SP = "100" /"100 + v% " × SP with VAT
= "100" /"100 + 10 " × 99000
= "100" /"110 " × 99000
= Rs. 90000 ∴ VAT Amount = SP with VAT – SP
= Rs. 99000 – 90000
= Rs. 9000 Again, MP = "100" /"100 – d% " × SP
= "100" /"100 – 10 " × 90000
= "100" /"90" × 90000
= Rs. 100000
∴ Discount Amount = MP – SP
= Rs. 100000 – 90000
= Rs. 10000
Step-by-step explanation:
Here is the list of all formulas on MP, Discount, SP, and VAT.
1. Discount Amount = Discount % of MP
2. Discount % = (Discount Amount)/MP ×100%
3. SP = MP – Discount Amount
4. SP = (100 - d%)/(100 ) × MP
5. MP = 100/(100 - d% ) × SP
6. VAT amount = VAT percent of SP
7. VAT percent = (VAT Amount)/SP ×100%
8. SP with VAT = SP + VAT amount
9. SP with VAT = (100 + v%)/(100 ) × SP
10. SP = 100/(100 + v% ) × SP with VAT
11. MP = (100 × 100)/((100 - d%)(100 + v%)) × SP with VAT
12. SP with VAT = ((100 - d%)(100 + v%))/(100 × 100) × MP
the answers are
A) Yes
B) No
