sorry I just know its 12 I promise
Answer:
Step-by-step explanation:
Let the two numbers be x and y
x = y - 5......(1)
2y = 3x.......(2)
Putting (1) into (2)
2y = 3(y - 5)
2y = 3y - 15
Collecting like terms
2y - 3y = -15
-y = -15
y = 15
Putting y = 15 in (1)
x = y - 5
x = 15 - 5
x = 60
Answer:
The number is 2.
Step-by-step explanation:
Let x represent the missing number and write an equation based on the information given, and solve for x
9x + 6 = 3 * 8
Simplify
9x + 6 = 24
Subtract 6 from both sides
9x + 6 - 6 = 24 - 6
9x = 18
Divide both sides by 9 to isolate x, and solve
9x ÷ 9 = 18 ÷ 9
x = 2
Answer:
The quotient is : x+9
The remainder is : 13
Step-by-step explanation:
The question requires you to perform the long division method;
This will be;
start with the x term in x-2 and the first term in the function, x², to get x then multiply the x with x-2 to get x²-2x and perform the operation below;
x-2√x²+7x-5 -----------to first get x and then multiply x*[x-2]⇒x²-2x
- x²-2x+0 ------------perform subtraction of like terms
---------------------
9x-5 ----now divide this answer by x-2 ,starting with x and 9x
----------------------This will give , 9 then multiply 9 by x-2 to get 9x-18 and perform the subtraction operation as;
9x-5
- 9x-18
------------------------
13
So the answer will be; x+9 remainder 13

Answer:
50 square units
Step-by-step explanation:
The outside square is 10 units on each side. If you fold the figure along each side of the shaded square, you find the white triangles exactly fill the shaded area. That means the shaded area is equal to the white area, so the shaded square is half the total area of 10×10 = 100 square units.
The shaded area is 50 square units.
