What is the solution to the inequality -8x + 4 < -4?

never [62]

Answer:

x > 1

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Step-by-step explanation:

Step 1: Define

-8x + 4 < -4

Step 2: Solve for x

Subtract 4 on both sides: -8x < -8
Divide -8 on both sides: x > 1

Here we see that any value x greater than 1 would work as a solution.

Evaluate the expression if m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5 , and t = − 2 | 16 + 4 ( 3 q + p )

Arisa [49]

The evaluation of the expression, if m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5 , and t = − 2 | 16 + 4 ( 3 q + p ) is 46.

<h3>How can the expression be simplified?</h3>

the given expression is t = − 2 | 16 + 4 ( 3 q + p )

Then since we are given m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5

Then, we can substitute all the given values of the terms into the given expression as :

t = − 2 | 16 + 4 ( 3 q + p )

t= -2 I 16+4(-18+2)

t= -2 I 16+4(-16)

t= -2 I 16 -64

t= -2 I -48

t =46

set up and solve a system of equations to solve the problem The school band sells carnations on Valentine's Day for $3 each. It

sasho [114]

Answer:

Number of carnations = 6

Step-by-step explanation:

Let the number of carnations school band buys from florist be x.

Cost of each carnation = $0.50

Total cost for x number of carnations = $0.50x

Also , delivery cost = $15

So, total cost on buying x number of carnations from florist = 0.50x + 15

Now,

School band sells carnations at a price of $3 each.

Total revenue they get get after selling x number of carnations = $3x

We need to find that , when will the cost of the carnations be equal to the revenue from selling them.

i.e 3x = 0.50x + 15

or 3x - 0.50x = 15

or 2.50x = 15

or x = $\frac{15}{2.50}$

or x = 6

so on selling 6 carnations cost of carnation reach to the point where it is equal to revenue
