Answer:
x=35
y=72.5
Step-by-step explanation:
The algebraic expression of the statement is 4x + 6
<h3>How to determine the
algebraic expression?</h3>
The statement is given as:
The sum of four times a number and six
Rewrite as:
The sum of 4 times a number and 6
Let the number be x
So, we have
The sum of 4 times x and 6
Evaluate the product
The sum of 4x and 6
Evaluate the sum
4x + 6
Hence, the algebraic expression of the statement is 4x + 6

Answer:
1,600
Step-by-step explanation:
C=4.00
A=8.00
C+A=2,350
C=2,350-A
4C+8A=12,400
4(2,350-A)+8A=12,400
9,400-4A+8A=12,400
4A=12,400-9,400
4A=3,000
A=3,000/4
A=750 ADULTS ATTENDED.
C+750=2,350
C=2,350-750
C=1,600 CHILDREN ATTENDED.
Answer:
10 edges
Step-by-step explanation:
we know that
The Euler's formula state that: In a polyhedron, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
in this problem we have
substitute the given values
solve for E
Combine like terms in the left side
subtract 12 both sides
Multiply by -1 both sides
Answer:
m = dv
Step-by-step explanation:

What you just do is multiply <em>v</em> on both sides so <em>m</em> can be isolated.
