Answer: <u>2x+y=-8</u> = <u>x=-1/2y-4 </u>
<u>4x-6y=-24 </u>= <u>x =3/2y-6</u>
Step-by-step explanation:
2x+y=-8 -- Step 1: Add -y to both sides.
2x+y+−y=−8+−y
2x=−y−8
Step 2: Divide both sides by 2.
2x/2=-y-8/2
<h3 />
4x-6y=-24 -- Step 1: Add 6y to both sides.
4x−6y+6y=−24+6y
4x=6y−24
Step 2: Divide both sides by 4.
4x/4=6y-24/4

Answer:
8
Step-by-step explanation:
plug in the number 4, it would be 5•4-12
Do 5•4=20
20-12=8
3n - 4 = 2✓
n = 2
3×2 - 4 = 6 - 4 = 2 ✓
3n - 4 = 2
n = -2/3
-6/3 - 4 = -2 - 4 = -6 wrong
Answer:
688 cm²
Explanation:
Area of triangular prism = Base × Height + Length × (perimeter of base)
Here given:
- Perimeter of Base: (6 + 12.4 + 12.4) = 30.8 cm
============================================
Surface Area = 6 × 12 + 20 × (30.8) = 688 cm²
