The answer could be (6,3) or ( -3,8)
Answer:
Start by writing an equation with a a variable (call it X) to represent the number Dan started with.
He started with X, added 5 more, then his dog took half or divide by 2. He then ended up with 32. Solve:
(X +5)/2 = 32 Multiply each side by 2
X+5 = 64 Subtract 5 from both sides
X = 59
Answer:
The complement of an event A is the collection of all outcomes in the sample space that are not in A.
Step-by-step explanation:
We have to fill the sentence in the given question:
Complement of an event:
- Let A be an event, then complement of an event is defined as the the event with outcome not in A.
- It is represented as A'
- We can write
Thus, we can fill the bank as
The complement of an event A is the collection of all outcomes in the sample space that are not in A.
The answer is isosceles.
Explanation:
Isosceles triangle is where two side lengths are equal.
Equilateral triangle is where all side lengths are equal.
Scalene Triangle is where all side lengths have different measures.
Since this triangle has two side lengths with the same measure it is an isosceles triangle.
Using a system of equations, it is found that they sold 23 pieces at $9.50.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given by:
- Variable x: Amount sold at $9.50.
- Variable y: Amount sold at $7.50.
They sold 90 pieces, hence:
x + y = 90.
Since we want x:
y = 90 - x.
They earned $721, hence:
9.5x + 7.5y = 721.
Since y = 90 - x:
9.5x + 7.5(90 - x) = 721
2x = 46
x = 23.
They sold 23 pieces at $9.50.
