Answer:

x = 7/4

Step-by-step explanation:

4x + 3 = 10

4x = 10 - 3

4x = 7

x = 7 ÷ 4

x = 7/4

hope that helps...

Hello there! I am EnjoyingLife, and I hope you find my answer helpful :)

The first step is to subtract 3 from both sides (remember the Golden Rule of Algebra: Whatever we do to one side, we do to the other)

[tex]\tt{4x+3-3=10-3}[/tex]

[tex]\tt{4x=10-3}[/tex]

[tex]\tt{4x=7}[/tex]

Divide both sides by 4 in order to isolate x:

[tex]\tt{x=\frac{7}{4}[/tex]

Hope it helps!

Have an amazing day!

Good luck!

The Carlos pay in service charges is $1721.3  

We have given that the Carlos took seven years to pay off his loan by making identical quarterly payments.

The loan had a principal of $22,375 and 5.49% interest, compounded quarterly.

P=22375 and interest rate =5.49%

Carlos paid a total of $28,821.67.  

We have to find how much did Carlos pay in service charges

First we find the monthly payment of the loan

The formula for monthly payment is,

[tex]M=\frac{amount}{discount}[/tex]

Discount factor

[tex]P=\frac{1-(1+i)^{-n}}{i} \\[/tex]

Where, Amount = $22,375 and r=0.0549 and compounded quarterly therefore n=4

[tex]i=r/n=0.0599/4[/tex]

i=0.0137

Time =7 years

[tex]n=4\times 7=28[/tex]

Now put all the values in above formula we get

[tex]P=\frac{1-(1+0.01372)^{-28}}{0.01372}\\\\P=\frac{1-(1+0.1372)^{-28}}{0.01372}\\\\P=\frac{1-0.6827}{0.01372}\\\\P=\frac{0.3172}{0.01372}\\\\P=23.11[/tex]

Monthly payment,

Use the value in the formula of monthly payment

[tex]M=\frac{22375}{23.1177}[/tex]

[tex]M=967.871[/tex]

The payment he has for for 7 years compounded quarterly that is  for 28

Therefore the payment,

[tex]Payment= 967.871 \times 28 = $27100.39[/tex]

[tex]Service charges = Total payment - payment[/tex]

                           [tex]= $28,821.67 - $27100.39[/tex]

                           [tex]= $1721.27[/tex]

Therefore, Carlos pay in service charges is $1721.3

Step-by-step explanation:

You calculate range by first putting all the numbers in order. Then subtract the lowest number from the highest.

What the question is thats how to calculate the median.

Have a wonderful day!

From the definition of the range, we understood that the given statement is false.

The given statement is "The range is calculated by adding the highest and lowest scores in a data set and then dividing by the number of scores in the dataset".

We need to state whether the given statement is true or false.

The range formula is mostly used in statistics to determine the range given in a particular data set. The formula helps in determining the centre of the set by finding the difference between the lowest and the highest number. In distribution, the large range means higher variability whereas the small range means low variability. The range formula includes the other aspects of statistics such as mean, median, and mode. Hence, the formula to calculate the range is:

R = Highest Value (H) - Lowest Value (L).

Therefore, from the definition of the range, we understood that the given statement is false.

Answer:

Step-by-step explanation

Perpendicular lines have slopes that are negative reciprocals of one another.

so, in this case, the given slope is 2.

The negative reciprocal of that would be -1/2.

so far, our equation looks like: y=-1/2x+b

now, take the point given to us, (-4,2) and plug it into the y and x values.

2= -1/2(-4) +b

2= b+2

b=0

Our y intercept is zero, so our final answer will be:

[tex]y=-\frac{1}{2} x[/tex]

Answer:

- 8x > 24

Step-by-step explanation:

Given

- 6x - 10 > 14 + 2x ( subtract 2x from both sides )

- 8x - 10 > 14 ( add 14 to both sides )

- 8x > 24 ← required missing step

Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity.

x < - 3 ← is the solution

Answer:

A

Step-by-step explanation:

the order does not matter just the numbers and signs

For the given exponential function, the change represents a growth  and the percentage rate is 0.3%.

The formula for the exponential function is:

[tex]y(t)=y(0)*(1+R)^t[/tex], where:

y(t)= final value

yo=initial value

R=rate

t= time

When 1+R  > 1, the equation represents growth, while 1+R < 1 the equation represents decay.

The question gives:  [tex]y=30*(1.003)^x[/tex].

When you compare [tex]y=30*(1.003)^x[/tex]with [tex]y(t)=y(0)*(1+R)^t[/tex], it is possible to see:

1. 1+R=1.003, so >1 . Therefore, the change represents growth.

2. 1+R=1.003 , therefore,

                           1.003=1+R

                          R=1.003-1

                          R=0.003

                          then,

                         %R=0.003*100=0.3%

1- angle JZF

supplementary angle or straight angle =180 degree

HZJ+JZF=HZF straight angle

2- JZA

complementary angle or right angle =90 degree

HZJ+JZA=HZA ( right angle)

if angle HZJ=38 degrees

HZJ+FZJ=180

FZJ=180-38

HZG+HZJ=180

HZG=180-38=142 degrees ( which is vertical angle to FZJ and equal to it)

The inequality which is used to find the number of cups of yogurt Monica can buy is,

[tex]1.20x+2.5\leq20[/tex]

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Monica needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. Let suppose the number of cups of yogurt bought by Monica is x.

As she has only $20. Thus, the inequality expression which can be used for this condition is,

[tex]1.20x+2.5\leq20[/tex]

Solve the above equation and find the value of x,

[tex]1.20x\leq20-2.5\\1.20x\leq17.5[/tex]

Divide both side with 1.20,

[tex]x\leq\dfrac{17.5}{1.20}\\x\leq14.58\overline3[/tex]

Hence, the number of cups she can Monica is 14.

Thus, the inequality which is used to find the number of cups of yogurt Monica can buy is,

Answer:

$646.25 is her earnings when selling $975.

Her earnings when selling $x is 500 + 0.15x.

Step-by-step explanation:

You know that her guaranteed salary is $500, and she also gets a commission that is 15% of her sales. So, the expression is

500 + 0.15x

Where x is total sales. When you are given $975 as her total sales, plug it in for x:

500 + 0.15(975)

500 + 146.25

$646.25 is her earnings when selling $975.

Her earnings when selling $x is 500 + 0.15x.
