Simplify the expression and explain each step . 4(3x+2)-2

2 answers:

4 0

Ok, so first we distribute "4" over 3x and 2. Distributing is basically multiplying the value next to the parenthesis by the values inside. From there, you get 12x+8-2. Then, you combine like terms, subtracting 2 from 8. The simplified expression is 12x+6!! :) Hope I helped!

X+y=13 2x-y=5 solve using any method

Alenkinab [10]

Answer:

x = 6 , y = 7

Step-by-step explanation:

solving by substitution method

x + y = 13

x = 13 - y equation (i)

2x - y = 5

substitute the value of x

2(13 - y) - y = 5

26 - 2y - y = 5

26 - 3y = 5

26 - 5 = 3y

21/3 = y

7 = y

substitute the value of y in equation (i)

x = 13 - y

x = 13 - 7

x = 6

You are riding the bus to school and you realize it is taking longer because of all the stops you are making. The time it takes

Sedaia [141]

Answer:

7 minutes

Step-by-step explanation:

If x represents the number of stops, and there are 2 stops after you board, solving g(2) will give you the time it takes to get to school allowing time for x = 2 stops:

$g(2)=(2)^4-3(2)^2+4(2)-5$

This gives you, in minutes, that

g(2) = 7

Samantha has a shelf that is 95 over 4 inches wide. How many books can Samantha arrange on the shelf if each book is 5 over 4 in

inysia [295]

Namely, how many times does 5/4 go into 95/4? well, let's just divide,

$\bf \cfrac{\quad \frac{95}{4}\quad }{\frac{5}{4}}\implies \cfrac{95}{\underline{4}}\cdot \cfrac{\underline{4}}{5}\implies \cfrac{95}{5}\implies 19$

Solve the system of equations below by graphing both equations with a pencil and paper. What is the solution? y = x+1 1 X+ 3 2.

Troyanec [42]

Answer:

D. (4, 5)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Solving systems of equations using substitution/elimination
Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

y = x + 1

y = 1/2x + 3

Step 2: Solve for x

Substitute in y: x + 1 = 1/2x + 3
Subtract 1/2x on both sides: 1/2x + 1 = 3
Subtract 1 on both sides: 1/2x = 2
Divide both sides by 1/2: x = 4

Step 3: Solve for y

Define original equation: y = x + 1
Substitute in x: y = 4 + 1
Add: y = 5

Step 4: Graph

We can confirm our answer.
