Solve algebrically 3x - 4y = -24 and x + 4y = 8 is x = -4 and y = 3
<u>Solution:</u>
We have been given two equations which are as follows:
3x - 4y = -24 ----- eqn 1
x + 4y = 8 -------- eqn 2
We have been asked to solve the equations which means we have to find the value of ‘x’ and ‘y’.
We rearrange eqn 2 as follows:
x + 4y = 8
x = 8 - 4y ------eqn 3
Now we substitute eqn 3 in eqn 1 as follows:
3(8 - 4y) -4y = -24
24 - 12y - 4y = -24
-16y = -48
y = 3
Substitute "y" value in eqn 3. Therefore the value of ‘x’ becomes:
x = 8 - 4(3)
x = 8 - 12 = -4
Hence on solving both the given equations we get the value of x and y as -4 and 3 respectively.
All you have to do is find a least common multiple for 6 and 8 in this case it would be 24 because 6's multiples are 6,12,18,24 and 8's multiples are 8,16,24 and many more but these are the lcm so in it would be
morning- 20/24
and
afternoon - 15/24
the answer is the morning
Answer:
the area of the glass is 1000cm^2
Step-by-step explanation:
Given that
The side is 50 cm
And, the power is 40 cm
We need to find out the area of the glass
So, the area of the glass is
= (50 × 40 ) ÷ 2
= 2,000 ÷ 2
= 1,000 cm^2
Hence, the area of the glass is 1000cm^2
The same is to be considered and relevant
