What is a unitary method?
A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Deron recorded his heart rate as 204 beats in 3 minutes.
∴ How many times his heart beats in one minute or the unit rate in beats per minute can be obtained if we divide the total no. of beats by total no. of minutes which is,
= (204/3) beats per minute.
= 68 beats per minute.

- 4x +2=-22
X=?
Plz help
Answer:
x = 6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-4x + 2 = -22
Step 2: Solve for x
Subtract 2 on both sides: -4x = -24Divide -4 on both sides: x = 6Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -4(6) + 2 = -22Multiply: -24 + 2 = -22Add: -22 = -22Here we see that -22 does indeed equal -22.
∴ x = 6 is a solution of the equation.

Ingrid dug a trench eighteen twentieths of a meter long. The next day she dug nine twentieths of a meter more of the trench. What is a reasonable estimate of the total length of the trench?
A) one half meter
B) 1 meter
C) one and one half meters
Answer:
Solution :-
On first day, Ingrid dug eighteen twentieth of a meter = (18/20) of 1 meter = (18/20) * 1 = (9/10) meters .
Now,
→ Next day, Ingrid dug nine twentieth of a mater = (9/20) of 1 meter = (9/20) * 1 = (9/20) meters .
So,
→ Total length of the trench = Ingrid dug in first day + Ingrid dug next day = (9/10) + (9/20) = (9*2 + 9)/20 = (18 + 9)/20 = (27/20) = 1.35 meters.
Therefore,
→ Total length of the trench = 1.35m ≈ 1.00 meter .
Hence, a reasonable estimate of the total length of the trench is 1.00 meter.

Yes you have to do a² + b² = c²
So the bottom triangle is 3 and 4 so plug in.
4² + 3² = c² (simplify)
16 + 9 = c²
25 = c² (square root both sides)
5 = c
That gives us the vertical side of the second triangle.
So plug in again
5² + b² = 13² (simplify)
25 + b² = 169 (subtract 25 on both sides)
b² = 144 (square root both sides)
b = 12
x = 12
