4x+1=2x-5 show all steps and solve for x

Answers

Answer 1

Answer:

x = -3

Step-by-step explanation:

4x + 1 = 2x - 5

~Subtract 1 to both sides

4x = 2x - 6

~Subtract 2 to both sides

2x = -6

~Divide 2 to both sides

x = -3

Best of Luck!

Answer 2

Final Answer: [tex]x = -3[/tex]

Steps/Reasons/Explanation:

Question: Solve [tex]4x + 1 = 2x - 5[/tex].

Step 1: Subtract [tex]2x[/tex] from both sides.

[tex]4x + 1 -2x = -5[/tex]

Step 2: Simplify [tex]4x + 1 - 2x[/tex] to [tex]2x + 1[/tex].

[tex]2x + 1 = -5[/tex]

Step 3: Subtract [tex]1[/tex] from both sides.

[tex]2x = -5 - 1[/tex]

Step 4: Simplify [tex]-5 - 1[/tex] to [tex]-6[/tex].

[tex]2x = -6[/tex]

Step 5: Divide both sides by [tex]2[/tex].

[tex]x = -\frac{6}{2}[/tex]

Step 6: Simplify [tex]-\frac{6}{2}[/tex] to [tex]-3[/tex].

[tex]x = -3[/tex]

I need help on having a equations for the bunny and the cat.

Answers

Answer:

BUNNY: y = 3x + 5

CAT: y = 1x + 19

Step-by-step explanation:

Answer:

Bunny: 5 + 3y

Cat: 19 + y

Step-by-step explanation:

If we were trying to make an equation about the total number of pounds each animal weighs, we would take the current number of pounds for each animal and then add the product of the pounds they gain and the number of years.

Bunny: 5 + 3y

y - number of years

5 current pounds  + 3 additional pounds * y

Cat: 19 + y

y -  number of years

19 current pounds + 1 additional pound per year or just 'y'

Solve for x in the triangle below. Show your work!

Answers

Answer:

x = 48°

Step-by-step explanation:

In the given triangle XYZ,

Sides XY and XZ are congruent.

Therefore, both the sides will be equal in measure.

By the definition of isosceles triangle,

"Opposite angles of the equal sides are equal in measure"

m∠Y = m∠Z = x°

m∠X = 84° [Given]

By the triangle sum theorem,

m∠X + m∠Y + m∠Z = 180°

84° + x° + x° = 180°

2x = 180 - 84

x = 48°

Therefore, measure of x = 48° will be the answer.

The missing angle is about 27.92°.

Step-by-step explanation:

This is a tangent equation, as there is no hypotenuse value. I'll use x as the missing angle.

tan(x) = opposite/adjacent

tan(x) = 20/38

tan(x) = 0.52631578947368421052631578947368

tan(x) ≈ 0.53

Now, we have to reverse.

tan⁻¹(0.53) = x

27.92358972 = x

x ≈ 27.92°

Only 6% of customers buy all three items. Let A be the event that the customer purchases a suit, B the event that the customer purchases a shirt and C the event that the customer purchases a tie. If there are 1000 customers in the store one week, how many will purchase exactly one of these items

Answers

Answer:

If there are 1000 customers in the store one week, how many will purchase exactly one of these items

1000 CUSTOMERS*28%=280

Step-by-step explanation:

A The event that a persons buys a suit  

B The event that a person buys a shirt  

C The event that a person buys a tie  

 

P(A)=  22%

P(B)=  30%

P(C)=  28%

P(AB)= 11%

P(AC)= 14%

P(BC)= 10%

P(ABC)= 6%

A u B u C Is the event that any item is bougth

AC u AC u BC Is the event that any two events occured

So the wanted probability is

P[(A u B u C )(AB u AC u BC)^c

P[(A u B u C )=P(AB)+ P(BC)+P(BC)

P[(A u B u C ) =0.22+0.30+0.28-0.11-0.14.-0.10+0.06

                      =0,51

0,51=+0,23+P[(A u B u C )(AB u AC u BC)^c

        =0,28

1000 CUSTOMERS*28%=280

A family eats at a restaurant. The bill is $42. The family leaves a tip and spends $49.77.
1. How much was the tip in dollars?
2. How much was the tip as a percentage of the bill?

Answers

Answer:

Because the total is 49.77 and the total is the bill + tip, then the tip is 49.77 - 42 or $7.77. To find the percentage, we just calculate 7.77/42 as a percentage to get 1.11/6 = (111/6)% or 37/2 percent or 18.5%

Remember your terms, whether it be PEMDAS / GEMS. I am going off GEMS so:

Grouping which are the parentheses; -8(1+7n) = -8-56n.

Next, combine your like terms:

-5n-8-56n=-8

-61n-8=-8

Add 8 to both sides, remember what you do to one side, you do to both sides.

-61n=0

Divide both sides by -61, your answer is 0.
