Answer:
The value of x is (-4) and y is (-5)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
<h3><u>To Find</u>;</h3>
Now,
-6x = 24
-6x/(-6) = 24/(-6)
x = -4
So, Substitute the value of x in x – 5y = 21
x – 5y = 21
-4 – 5y = 21
-4 + 4 – 5y = 21 + 4
-5y = 25/
-5y/(-5) = 25/(-5)
y = -5
Thus, The value of x is (-4) and y is (-5)
<h3>
<u>For </u><u>Verification</u>;</h3>
x – 5y = 21
-4 – 5(-5) = 21
-4 + 25 = 21
21 = 21
-6x = 24
-6(-4) = 24
24 = 24
L.H.S = R.H.S
Hence Verified!

Answer:
The area of the base is = 5.2 cm²
Step-by-step explanation:
<em>First, we need to know the formula to calculate volume:</em>
<em>if we change to our equations to the values we know:</em>
<em>Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:</em>
<em>We calculate the operation=</em>
<em>And the answer is 5.2 cm²</em>
<em>Let me know if you have any question :D</em>
Ok first you have to multiply and get scammed
A is the answer............ If you plot it on a graph, it shows a square.
