Answer:
y = 8
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
48 = y + 5y
<u>Step 2: Solve for </u><em><u>y</u></em>
- Combine like terms: 48 = 6y
- Divide 6 on both sides: 8 = y
- Rewrite: y = 8
<u>Step 3: Check</u>
<em>Plug in y into the original equation to verify it is a solution.</em>
- Substitute in <em>y</em>: 48 = 8 + 5(8)
- Multiply: 48 = 8 + 40
- Add: 48 = 48
Here we see that 48 does indeed equal 48.
∴ y = 8 is a solution of the equation.
Speed = (75 mi/hr) · (1,609.344 mt/mi) · (1 hr/3,600 sec) =
Speed = (75 · 1,609.344 / 3,600) (<em>mile</em>·meter·<em>hour</em> / <em>hour·mile</em>·second)
<em>Speed = 33.5 meter/second</em>
Answer:
z = 45.6
Step-by-step explanation:
because the triangle that we know all the length is similar to the large triangle,
z = 27/(16/27)= 45.5625
