x=90
x=30
x=180

Solve The Following Equation By Using Inverse Operations To Find The Value Of X. Hint: The Sum Of All

Answers

Answer 1

Answer:

[tex] x = 30 [/tex]

Step-by-step explanation:

Given [tex] 2x, 3x, x [/tex], as the interior angles of the ∆, since sum of interior angles of ∆ = 180°, equation to solve for the value of x is given as:

[tex] 2x + 3x + x = 180 [/tex]

Combine like terms

[tex] 6x = 180 [/tex]

Apply the inverse operation of multiplication to solve for x. Since 6 is multiplying x = 6x, to get the value of x, the inverse operation of multiplication is division. Therefore, we would divide each side of the equation by 6.

[tex] \frac{6x}{6} = \frac{180}{6} [/tex]

[tex] x = 30 [/tex]

(07.01) Which of the values for x and y make the equation 2x + 3y + 4 = 15 true? x = 6, y = 3 x = 3, y = 5 x = 6, y = 4 x = 1, y = 3

Answers

Answer:

x = 1, y = 3

Step-by-step explanation:

Given:

2x + 3y + 4 = 15  ⇒ 2x + 3y = 11

Now let's check the pairs of x and y:

x = 6, y = 3

2x + 3y = 2*6 + 3*3 = 12 + 6 = 18 ≠ 11incorrect

x = 3, y = 5

2x + 3y = 2*3 + 3*5 = 6 + 15 = 21 ≠ 11incorrect

x = 6, y = 4

2x + 3y = 2*6 + 3*4 = 12 + 12 = 24  ≠ 11incorrect

x = 1 , y = 3

2x + 3y = 2*1 + 3*3 = 2 + 9 = 11correct

Answers

Answer:

80

Step-by-step explanation:

Initial ratio:

Teachers to students

1 : 15

Ratio after:

Teachers to students

3 : 40

The number of students did not change, so we can make the students of the initial ratio and the students of the ratio after the same.

1 : 15 =  8 : 120

3 : 40 = 9 : 120

120 units = 1200

1 unit = [tex]\frac{1200}{120} =10[/tex]

Initial teachers = 8 units = [tex]8*10=80[/tex]

1. Jim opens a savings account with $22,500. His account pays 3.5% simple interest. At the end of 5.5 years, Jim closes the account. How much interest does he earn? What is the total value of his account when he closes it?

Answers

Answer:

$27186.57

Step-by-step explanation:

Formula: start(interest)^time

First, we need to calculate the interest which in this case would be 1.035 (1+(3.5/100)) since it is increasing 3.5% each year. Then we can just plug the values into the formula to get:

22,500(1.035)^5.5 = 27186.57
