Answer:15
Step-by-step explanation:
he will have 15 because he earned 15 more dollars and that would equal 30 -15 would be 15
15 +15=30 -15= 15
<h3>
Answer:</h3>
- One solution: (x, y) = (2, 0)
- Infinitely many solutions: 2x -5y = 17
<h3>
Step-by-step explanation:</h3>
1. When you put the second equation in standard form, it is ...
... 5x +3y = 10
This is a different equation than the first one, so there will be one solution where the lines interect. (Adding the two equations gives 10x=20 ⇒ x=2. Since adding or subtracting y gives the same result, y must be zero.)
2. When you put the second equation in standard form, it is the same as the first:
... 2x -5y = 17 . . . . . divide the equation by 3
That is, any (x, y) values that satisfy the first equation will also satisfy the second equation (since they are the same). There are an infinite number of (x, y) values that do so.
An expression is defined as a set of numbers, variables, and mathematical operations. The term that best describes 3 is coefficient.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The value of 3 in the expression, 9 + 4(x + 2) - 3x, is that it is the coefficient of x in the third term.
Hence, the term that best describes 3 is coefficient.

Answer:
Step-by-step explanation:
Priya will make b loaves of banana bread using f cups of flour.
She uses 
cups of flour to make 4 loaves of banana bread.
It implies,
Cross multiplying both sides,
Hence, the correct option is (d).
64-18 is 46
46/2 is 23
23+18 is 41
Your #s are 21 and 43
