Which algebraic expression represents the following: the sum of four times a number and six? (1 point) 4x + 6
jeka94

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

The admission fee at a concert is $4.00 for children and $8.00 for adults. On the first day, 2350 people enter the concert and $
rjkz [21]

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.

If a polyhedron has 5 faces and 7 vertices, then it must have how many edges? Please show step-by-step work
Juli2301 [7.4K]

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

V - E + F = 2

in this problem  we have

V=7\\E=?\\F=5

substitute the given values

7 - E + 5 = 2

solve for E

Combine like terms in the left side

12 - E = 2

subtract 12 both sides

- E = -10

Multiply by -1 both sides

E =10

D = m/v solve for m
lora16 [44]

Answer:

m = dv

Step-by-step explanation:

\\\\d=\frac{m}{v} \\\\\d*v=\frac{m}{v} *v\\dv=m

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