his dad paid him 15 dollars to mow the lawn three times. from this we know he gets paid 5 dollars for every time he mows. if he mows five times, he should expect 25 dollars because 5 times five is 25.
Answer:
16 ounces each
Step-by-step explanation:
1 gallon equals 128 ounces so 1.5 gallons would be 192 ounces. Divide 192 by 12 and you'll get 16.
Answer:
Step-by-step explanation:
In sets theory n(A) represents the number of elements in set A.This number is the cardinal number of the set A.
For n(AUB) there is an equation that relates n(A),n(B) and n(A∩B) :
n(AUB) = n(A) + n(B) - n(A∩B)
In our exercise :
n(AUB) = n(A) + n(B) - n(A∩B)
Another important equation for maths is similar to this one :
P(AUB) = P(A) + P(B) - P(A∩B)
Where ''P'' is the event probability.This equation is used in probability and statistics.
The area of the figure is 19.

General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
7x + 3y = 12
7x - 3y = 30
<u>Step 2: Solve for </u><em><u>x</u></em>
- Eliminate <em>y</em>: 14x = 42
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em>: 7(3) + 3y = 12
- Multiply: 21 + 3y = 12
- Isolate <em>y</em> term: 3y = -9
- Isolate <em>y</em>: y = -3
And we have our final answer!
