perimeter: 16, calculate
the value of x when the length
of the rectangle is 3x and the
hieght is x​

Answers

Answer 1

Step-by-step explanation:

Perimeter = 16

length = 3x

height = x

P = 2L + 2H

16 = 2(3x) + 2(x)

16 = 8x

hence:

x = 2.

Solve 4x + 1 = 3 – 2x

Answers

Answer:

x = 1/3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

4x + 1 = 3 - 2x

Step 2: Solve for x

Add 2x on both sides:                    6x + 1 = 3Subtract 1 on both sides:                6x = 2Divide 6 on both sides:                   x = 1/3

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                    4(1/3) + 1 = 3 - 2(1/3)Multiply:                        4/3 + 1 = 3 - 2/3Add/Subtract:               7/3 = 7/3

Here we see that 7/3 does indeed equal 7/3.

∴ x = 1/3 is a solution of the equation.

Answer:

x=1/3

Step-by-step explanation:

4x+1=3-2x

Add 2x to both sides

6x+1=3

Subtract 1 on both sides

6x=2

x=2/6

10x+8(1/3 x + 2/3) =-20

2. Simplfy

3. Subtract 16 from both sides

Twice Sam's age added to half her mother's age is 48. Three times her age less one third of her
mother's age is 33. How old are Sam and her mother?

Answers

Answer:

Sam is 15 and her mother is 36

Step-by-step explanation:

Let Sam's age be x and her mother's age by y

We can figure out Sam and her mother's age by representing these scenarios using equations with variables and solving the system using elimination

2x+y/2=48

3x-1/3y=33

You start by making all the numbers in both the equations whole

2(2x+y/2=48)

3(3x-1/3y=33)

Becomes:

4x+y=96

9x-y=99

Add together to eliminate y

13x/13=195/13

x=15

Now that we have x we can plug the value into the x in the equations to give us the y-value

2x15+y/2=48

30+y/2=48

30+y/2-30=48-30

y/2=18

2 X y/2=18 X 2

y=36

Therefore x=15 and y=36

Answers

Answer:

y=2x-5

Step-by-step explanation:

slope intercept form is y=mx+b

m=slope

b=y-intercept

Answer: y = 2x - 5

slope-intercept form ⇒ y = mx + b

⇒ where mx is the slope,

⇒ b is the y-intercept

⇒According to the question;

mx which is the slope = 2

b the y-intercept = -5
