Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.

Answers

Answer:

x = 11(13/14)

Step-by-step explanation:

3/5(x – 7/10) = -31/4

open the bracket:

3/5 * x – 7/10 = -31/4

3/5 * –7x/10 = -31/4

3/5 + 31/4 = 7x/10

(12+155)/20 = 7x/10

167/20 = 7x/10

cross multiply:

140x = 1670

x =1670/140

x = 11(130/140)

x = 11(13/14)

The value of x is 1/5.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3/5 (x − 7/10)= −3 1/4

Now, Solving for x

3/5 ( x- 7/10 )= 13/4

x- 7/10 = -13/4 x 5/3

x- 7/10 = -65 /12

x= -65/12 + 7/10

x= 24/ 120

x= 1/5

hence, the value of x is 1/5.

The cost of having photos taken includes a sitting fee and $12 for each portrait. The cost of 3, 6, and 9 photos respectively is $51, $87, and $123. What is the sitting fee? Use units in your answer and round answer to the hundredths place, for example $2.35
plz help

Answers

Answer:

The sitting fee is 15 dollars

Step-by-step explanation:

1 - 12 x 3 = 36

2 - 51 - 36 = 15

3 - 12 x 6 = 72

4 - 87 - 72 = 15

Answer:

$15.00

Step-by-step explanation:

cost of photos = sitting fee + $12 per photo

Let the number of photos = x

Let the sitting fee = s

cost of photos = s + 12x

cost of 3 photos = $51

s + 12(3) = 51

s + 36 = 51

s = 15

Answer: The sitting fee is $15.00

how can you find the product of positive and negative decimals

Answers

(I have attached an example for reference)

1) Product means multiply, so we will multiply the decimal numbers.

2) First multiply both the numbers just the way you multiply two whole numbers.

3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.

4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.

5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.

Which ordered pair would form a proportional relationship with the point graphed below?

Answers

Answer:

-10, 20 because -20, 40 divided by 2 = -10, 20

The ordered pair that would form a proportional relationship with the point (-20, 40) is given as follows:

(15, -30).

What is a proportional relationship?

A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable exists.

The equation that defines the proportional relationship is a linear function with slope k and intercept zero presented as follows:

y = kx.

The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.

The constant for this problem is given as follows:

k = 40/-20

k = -2.

Hence the equation is:

y = -2x.

When x = 15, the numeric value of the equation is given as follows:

y = -2(15)

y = -30.

Hence the point is:

(15, -30).
