Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -4x + 1
11y = x + 146
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 11(-4x + 1) = x + 146
- Distribute 11: -44x + 11 = x + 146
- [Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146
- [Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x
- [Division Property of Equality] Divide 45 on both sides: -3 = x
- Rewrite/Rearrange: x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = -4x + 1
- Substitute in <em>x</em>: y = -4(-3) + 1
- Multiply: y = 12 + 1
- Add: y = 13
The volume of the larger cube is 227 inches cube.
<h3 /><h3 /><h3>Volume of a cube is describe below:</h3>
where
L = length
The small cube has the following volume:
Let
The side length of the small cube = x
Therefore,
95 = x³
x = ∛95
x = 4.56290264
x ≈ 4.6
Its side length is 1.5 inches less than a second larger cube. Therefore,
- length of larger length cube = (x + 1.5 )inches = 4.6 + 1.5 = 6.1 inches
Therefore, the volume of the larger cube can be found as follows:
Volume = 6.1³
volume = 226.981
volume ≈ 227 inches³
