Answer:
(t+1)(t^2+1)
Step-by-step explanation:
t^3+t^2+t+1
(t+1)(t^2+1)
Let
x = number of rs 50
y = number of rs 20
z = number of rs 10
Because there are 25 total notes,
x + y + z = 25 (1)
The ratio of rs 50 to rs 20 is 3:5, therefore
x = 0.6y (2)
The total amount is rs 590, therefore
50x + 20y + 10z = 590
or
5x + 2y + z = 59 (3)
Subtract (1) from (3).
4x + y = 34 (4)
Substitute (2) into (4).
4*(0.6y) + y = 34
3.4y = 34
y = 10
From (2), obtain
x = 6
From (1), obtain
z = 25 - 6 - 10 = 9
Answer:
Kaveri has
6 rs 50 notes,
10 rs 20 notes,
9 rs 10 notes.
Answer:
x = -2
Step-by-step explanation:
-9x + 1 = -x + 17
To solve this equation
Note if there is more than one variable like x, y, or z
Also note the power of the variables, for example, x^2 or y^3
In this equation, there is only one variable which is x and it's also in the power of 1 ie x
Step 1 : rearrange according to like terms
-9x + x = 17 - 1
( don't forget that the sign always change on crossing an equals to, either + to - or - to +
-9x + x (also means 9 - 1 but only carries a negative sign)
= - 8x = 16
Dividing both sides by -8 to get the value of x
-8x / 8 = 16 /- 8
x = 16/ -8
x = -2
Answer:
A rational number is a number that stops and doesnt go on forever and ever. Therefore the sequence of numbers would be no, yes, no, yes, yes
Step-by-step explanation:
Any number that is a decimal that eventually stops is also rational but decimals that never end are irrational.
Not sure about 1 and 8, I think there trapezoids but not sure.
2 is a square
3 is a rectangle
4 and 10 are a rhombus
5 and 11 are parallelograms
6 is a kite
7 is a square
can't really see 9
can't really see 12
Hope that helped.
