What value of x makes this equation true? 2(4x-3) - 8= 4+2x​

Answers

Answer 1

Answer:

What value of x makes this equation true? 2(4x-3) - 8= 4+2x​  HERE YOU GO!!

Step-by-step explanation:

We need to eliminate one of the variables to solve the other.

 

4x+5y = 8

2x-3y = 18

I will multiply the second equation by -2.

 

-2*(2x-3y = 18)

-4x + 6y = -36 and then add the two equations

 

4x + 5y = 8

-4x + 6y = -36

+ adding here

11y = -24

y = -24/11

substitute x in one of the equations to find y.

2x-3y=18

2x - (3*-24/11) = 18

2x = 126/11

x = 126/22

2x - 3x = 33

what is it .?​

Answers

Answer:

- 33

Step-by-step explanation:

Step 1:

2x - 3x = 33       Equation

Step 2:

- x = 33      Subtract

Answer:

x = - 33

Hope This Helps :)

The solution to the equation 2x - 3x = 33 is x = -33.

To solve the equation 2x - 3x = 33, we need to combine like terms on the left side of the equation and then solve for x.

Combine like terms:

2x - 3x = -x

Rewrite the equation with the combined terms:

-x = 33

To isolate x, we need to multiply both sides of the equation by -1:

(-1)(-x) = (-1)(33)

This simplifies to:

x = -33

Therefore, the solution to the equation 2x - 3x = 33 is x = -33.

x= -4

Subtract 2x from both sides
6x−2x=−16

Combine 6x and −2x to get 4x.
4x=−16

Divide both sides by 4.
x= -16/4


Divide −16 by 4 to get −4.

A retiree has $200,000 to invest and needs to make $13,000 with her investments. If she can invest in government bonds at 6% or investment grade bonds at 8%, how much should she invest in each?

Answers

Answer:

She should invest 150,000 in government bonds and 50,000 in investment grade bonds

Step-by-step explanation:

Let the amount invested in government bonds be $y while the amount invested in investment bond be $x

Since total is $200,000

Then:

x + y = 200,000 ••••••(i)

Since 13,000 is what is expected to be earned, then this is like the interest.

thus;

6% of x + 8% of y = 13,000

6x/100 + 8y/100 = 13,000

Multiply through by 100

6x + 8y = 1300000 •••••••(ii)

From i, x = 200,000 - y

insert this into ii

6(200,000-y) + 8y = 1300000

1200000-6y + 8y = 1300000

2y = 1300000-1200000

2y = 100,000

y = 100,000/2

y = 50,000

but x + y = 200,000

thus, x = 200,000 - 50,000

x = 150,000

Step-by-step explanation:

Steve is first in the ratio if the ratio of guitars is 4:3.

What is Ratio?

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other. A set of data points can be used to observe the constant relationship. A set of data with a constant relationship between two values is a comparison of miles traveled to hours traveled. A special type of ratio is the comparison of two different quantities.

The general form of expressing a ratio between two quantities say 'a' and 'b' is a: b

Jenny has 3 guitars. Steve has 4 guitars.

The ratio is 4:3, which represents 4/3 or 4 parts Steve to 3 parts Jenny.

Hence, Steve is first in the ratio.

Caffenine takes a certain amount of time to leave your system if you drink 3 cups of coffe in the morning the function that represents the amount of caffeine remaining in your body after drinking the coffe is given by g(t)=130(.8346)^t where t is the timein hours. how much caffeine remains in your body after 1 day. how much caffeine remains in your body after 2 days

Answers

Answer:

In 1 day, 1.70

In two days 0.022

Note; Unit was not given in the question, I would have included it

Step-by-step explanation:

Here, we are to calculate the amount of caffeine remaining in the body.

To calculate this, we simply substitute for the number of hours t in the equation.

In one day , we have 24 hours

So our substitution will be t = 24

Hence; for a day;

g(24) = 130(0.8346)^24 = 1.70

For two days, we have t = 48 hours

Thus; g(48) = 130(0.8346)^48 = 0.022

3(x+-10)=5(2x+8) Honestly I hate math lol.

Answers

Hey :)

x = -10

Use the distributive property to multiply 3 by x−10
3x−30=5(2x+8)

Use the distributive property to multiply 5 by 2x+8
3x−30=10x+40

Subtract 10x from both sides
3x−30−10x=40

Combine 3x and −10x to get −7x.
−7x−30=40

Add 30 to both sides
−7x=40+30

Add 40 and 30 to get 70
−7x=70

Divide both sides by −7
x= 70/-7


Divide 70 by −7 to get −10


Hope this helps :)

Answer:

- 10

Step-by-step explanation:

Step 1:

3 ( x - 10 ) = 5 ( 2x + 8 )      Equation

Step 2:

3x - 30 = 10x + 40       Multiply

Step 3:

- 30 = 7x + 40     Subtract 3x on both sides

Step 4:

- 70 = 7x           Subtract 40 on both sides

Step 5:

x = - 70 ÷ 7         Divide

x = - 10

How are the rules for dividing two negative fractions related to the rules for multiplying
two negative fractions? Will the answer be positive or negative? Explain.

Answers

The answer will be negative, the rules are a negative plus a negative equals a positive and a positive plus a positive equals a negative

The relation between multiplying and dividing two negative fractions is needed.

When multiplying and dividing two negative fractions the answer will be always positive.

Let [tex]-\dfrac{a}{b}[/tex] be one fraction

and [tex]-\dfrac{c}{d}[/tex] be another fraction

Let us multiply them

[tex]-\dfrac{a}{b}\times -\dfrac{c}{d}=+\dfrac{ac}{bd}[/tex]

Let us divide them

[tex]\dfrac{-\dfrac{a}{b}}{-\dfrac{c}{d}}[/tex]

This can also be written as

[tex]-\dfrac{a}{b}\times -\dfrac{d}{c}=+\dfrac{ad}{bc}[/tex]

Since, multiplication and division are the inverse of each other the negative signs cancel each other and the sign is positive.

Hence, when multiplying and dividing two negative fractions the answer will be always positive.

You deposited $100 in a savings account 3 years ago. The simple interest rate is 2.3%. How
much money is in the account after 3 years?

Answers

Answer:

Final Balance = 106.90$

Step-by-step explanation:

Using the simple interest formula I = prt.

The current balance after accumulated interest is B = I + p.

Given a principle of $100, time of 3 years, and interest rate of 2.3%.

I = (100$)(3y)(2.3%) = (100)(3)(2.3%) = (300)(2.3%) = (300)(0.023) = 6.90$

B (final balance) = 6.90$ + 100$ = 106.90$

Answers

Answer:

y = 12

x = 10/3

Step-by-step explanation:

y = -3.6x + 12

From this equation, which is in slope intercept form (y = mx+b), we already know that b represents the y-intercept, so that means the y-intercept is 12.

To find the x-intercept, we need to make y equal 0 to find x. So:

0 = -3.6x + 12

-3.6x = -12

x = 3.33333 --> 3 1/3

x = 10/3

Answer:
x-intercept: 10/3
y-intercept: 12

Steps:
Finding x
y=-3.6x+12
0= -3.6x+12
3.6x=12
x=10/3

Finding y
y=-3.6x+12
y=-3.6(0)+12
y=12
