Step-by-step explanation:
So you add one over the other
3x-2y=7
-3x+5y=5
=
3y=12
Then you divide 3 from both sides
(3y)/3=12/3
y=4
Then you substitute the y=4 in to the equation of your choice
3x-2(4)=7
3x-8=7
3x-8=7
+8 +8
3x=15
x=5
Answer:
15 yd³
Step-by-step explanation:
Formula for the volume of a square pyramid is V = 1/3 Bh
So...
V = 1/3 (3*3)(5)
V = 1/3 (9)(5)
V = 1/3 (45)
V = 15
The answer would be 20,775,4




Divide both sides by -2. We know that since 2 is negative, it'll be < (less than) 0. So, the direction of inequality will change.

Divide 26 by -2..we'll get the answer as -13.

Now, subtract 3 from both the sides.

Subtracting -13 by 3..we'll get the answer as -16.

Divide both sides by 2. We know that since 2 is positive, the direction of inequality will remain the same.

Divide -16 by 2..we'll get the answer as -8.

- The correct answer is ⇨ <u>x </u><u>greater </u><u>than </u><u>or </u><u>equal</u><u> to</u><u> </u><u>-</u><u>8</u><u>.</u>
You need to use the cosine for this and this is how you do it.
