If you add the two equations 6x + 4y 46 and — 6x + 9y = 6 what do you get?
Answers
Answer:
13y = 52
Step-by-step explanation:
6x - 6x + 4y + 9y = (46 + 6)
6x - 6x + 4y + 9y = 52
0 + 4y + 9y = 52
0 + 13y = 52

Calculate the marked price (original price) if
a. After 25% discount, the price of an article is Rs 7500,
Answers
Answer:
Step-by-step explanation:
let original price of an article be x
marked price(price after discount )=Rs 7500
discount%=25%
discount =discount % of cost price
=25/100*x
=25x/100
=x/4
Mark price=original price-discount amount
Rs 7500=x-x/4
Rs 7500=4*x-x/4
Rs 7500*4=4x-x
Rs 30000=3x
Rs 30000/3=x
Rs10000=x
therefore original price of an article is Rs 10000.

Mateo compró un artefacto gastando los 3/7 de su dinero, quedándole 360 soles, ¿Cuál era el dinero que tenía Mateo al inicio?
Answers
Answer:
840 soles
Step-by-step explanation:
Sea la cantidad de dinero que Mateo tenía al principio = x
Mateo compró un artefacto gastando 3/7 de su dinero, dejándole 360 soles,
Por eso,
3/7 × x = 360 soles
3x / 7 = 360 soles
Multiplicar cruzada
3x = 7 × 360 soles
x = 7 × 360 soles / 3
x = 840 soles
Por tanto, el dinero que tenía Mateo al principio es de 840 soles

Greggory is trying to raise money for his school's football team by selling T-shirts and sweatshirts. The football team will get $3 for each sweatshirt sold and $4 for each T-shirt sold. The rest of the money goes to paying for the items to be sold. Greggory manages to sell a total of 121 items and the team ends up getting $406.
Answers
# of t-shirts sold = y = 43
We know:
x + y = 121
3x + 4y = 406
Solve the first equation for x in terms of y, then substitute that into the second equation.
x = 121 - y
3(121 - y) + 4y = 406
363 - 3y + 4y = 406
y + 363 = 406
y = 43
Then solve for x
x = 121 - y
x = 121 - 43
x = 78
Check the math:
3(78) + 4(43) = 234 + 172 = 406

A ladder is placed 10 feet away from a tree. The length of the ladder is 25 feet. Find the height of the tree?
STEP BY STEP PLS
Answers
Answer:
23ft approx
Step-by-step explanation:
Given data
Distance from tree= 10ft
Length of ladder= 25ft
We can find the height of the tree by applying the Pythagoras theorem
z^2= x^2+y^2
z= The height of the ladder
x= The distance from the tree
y= The height of the tree
25^2= 10^2+ y^2
625=100+y^2
625-100=y^2
525=y^2
y= √525
y= 22.91
Hence the height of the tree is 23ft approx

What is the first step you will use to solve this equation:
4x +2 = 7x - 13
Answers
1. Subtract 2 from both sides of the equation
4x + 2 = 7x - 13
4x + 2 - 2 = 7x - 13 - 2
2. Simplify
4x + 2 - 2 = 7x - 13 - 2 -----> 4x = 7x - 13 - 2 -----> 4x = 7x - 15
3. Subtract 7x from both sides of the equation
4x = 7x - 15
4x - 7x = 7x - 15 - 7x
4. Simplify
4x - 7x = 7x - 15 - 7x -----> -3x = 7x - 15 - 7x -----> -3x = -15
5. Divide both sides of the equation by the same term
-3x = -15
-3x/-3 = -15/-3
6. Simplify
-3x/-3 = -15/-3
x = -15/-3
x = 5
7. Solution
x = 5
