1/3 * 7/9 kg = (1 * 7)/(3 * 9) kg = 7/27 kg
He used 7/27 kg of sugar.
Answer:
x = 7
Step-by-step explanation:
Rearrange the equation to make x the subject.
Original:
7x + 3 = 52
subtract 3 from both sides
7x = 52 -3
7x = 49
Divide both sides by 7
x = 49/7
x = 7
5 1/6 i got my answer using math papa. high recommend you use it for equation problems.
X + 4 = 19 -2x
3x = 15
x=5
5 is the number
Answer:
The coordinates are x = -1 and y = -2.
Step-by-step explanation:
Given:
Equations are 2x-4y=6 and 3x+y=-5.
Now, to find the coordinates.
...........(1)
...........(2)
So, first we solve the equation 1 to get the value of
.

Subtracting both sides by
we get:

Dividing both sides by 2 we get:

Now, we put the value of
in equation 2 to get
.




On solving the whole equation we get :

And, now putting the value of
in equation (1) we get
:





on solving we get:

Therefore, the coordinates are x=-1 and y=-2.
