The factors of 30 are 1,2,3,5,6,10,15,30
Explanation:
Factors are whole numbers that are multiplied together to produce another number. The original numbers are factors of the product number.
If a x b = c then a and b are factors of c.
So we can write the number 30 as
30 x 1 = 30
15 x 2 = 30
10 x 3 = 30
6 x 5 = 30
So, all the possible factors of 30 are 1,2,3,5,6,10,15,30
Answer:
1,3,5,6,10,30
Step-by-step explanation:
use -9 to multiply the first equation
use -4 to multiply the second equation.
5x-4y=28.....eqn (1)×-9
3x-9y=30....eqn(2)×-4
-45x+36y=-252
-(-12x+36y=-120)
therefore, -33x÷33 =-132÷-33
x=4.
substitute (x=4) in any of the equation. I'm just going to use eqn 1.
5x-4y=28
5(4)-4y=28
20-4y=28
-4y =28-20
-4y÷-4 = 8÷-4
y=-2
so, x=4, y=-2
Note: for proof of answers substitute the answers for x and y and see if you have the same result...e.g
5(4)-4(-2)=28.
-7
Because for dividing one positive and one negative number, the rule is that the answer is going to be negative. So, what you can do is just do 56÷8 which equals 7 then add the negative sign to make it -7.
A. no
I hope it help............
-0.805 m
The x-component of a vector is given by:
where
v is the magnitude of the vector
is the angle of the vector with respect to the positive x-direction
In this problem we have
v = 0.888 m
so we have
x=1, y=4
Since they coincide at the point
(1,4)
Hence (x,y)=(1,4)
