Answer:

x=0

Step-by-step explanation:

- 7(x + 4) - 4= - 32

Add 4 to each side

- 7(x + 4) - 4+4= - 32+4

- 7(x + 4) = - 28

Divide by -7

- 7(x + 4) /-7= - 28/-7

x+4 = 4

Subtract 4 from each side

x+4-4 = 4-4

x=0

Answer and process:
-7(x-4) -4= -32
-7x +28 -4= -32
-7x +24 = -32
-7x = -32-24
-7x = -54
x= -54/7

1/4m + 3/4m - 3/8(m+1)
sammy [17]
Distribute 3/8 to m and 1 so now the equation should be 1/4m + 3/4m - 3/8m + 3/8

then add 1/4m 3/4 to get m. the equation should now look like m - 3/8m + 3/8

m is 1m but the one is invisible so subtract 3/8 from 1 now the equation should look like 5/8m + 3/8

final answer: 5/8 + 3/8

Classify the following Polynomial by the number of Terms
kvv77 [185]

Answer:

Trinomial

Step-by-step explanation:

we know that

A polynomial can be classified by its number of terms.

A polynomial with one term is called monomial, a  polynomial with two terms is called a binomial, and a polynomial with three terms is called a trinomial

In this problem we have

9x^3+2x^2+4x

This polynomial has three terms

therefore

Is a trinomial

Hank has 50 peso, 200 peso and 500 peso bills in his wallet. He has five less 200 bills as 50 bills, and half as many 500 bills
Varvara68 [4.7K]

For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso.

<h3>How to apply systems of linear equations in real life equations</h3>

In this question we must translate the statement of the problem into mathematical expressions and then we must solve the resulting system. We need three equations that describe the quantities of 50 peso, 200 peso and 500 peso bills:

<em>y = x - 5</em>     (1)

<em>0.5 · y =</em> <em>z</em>    (2)

<em>x + y + z = 6250</em>     (3)

The solution of the system of <em>linear</em> equations is described below:

<em>x =</em> 2503, <em>y =</em> 2498, <em>z =</em> 1249

For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso. \blacksquare
