Which number is in the solution set of this equation? 7x − 9 = 40

Answers

Answer 1

Answer: the answer is 7

Step-by-step explanation: add 9 to both sides, eliminating -9 so now you have 7x=49 divide both by 7 and you get x= 7 check it by inputing 7 for x, 7(7)-9=40

7(7)=49 next 49-9= 40

it checks out, so x= 7

Answers

Answer:

6⋅10^ −2 is 3* 10^6 greater than 2 ⋅ 10^− 8

Step-by-step explanation:

Given the following expression

6⋅10^ −2 and 2 ⋅ 10^− 8

Taking their ratio

k = 6⋅10^ −2/2 ⋅ 10^− 8

k = 6/2 * 10^-2/10^-8

k = 3 * 10^{-2+8}

k = 3* 10^6

Hence 6⋅10^ −2 is 3* 10^6 greater than 2 ⋅ 10^− 8

Answer:

x = 35 , y = 72.5

Step-by-step explanation:

(a)

x and 35° are vertical angles and are congruent, then

x = 35

(b)

y. y and 35 lie on a straight line and sum to 180°, that is

y + y + 35 = 180

2y + 35 = 180 ( subtract 35 from both sides )

2y = 145 ( divide both sides by 2 )

y = 72.5

Answer:

y = 72.5 degrees

X = 35 degrees

Step-by-step explanation: A straight line is 180 degrees. The line with the two y degrees and the 35 degrees is a straight line, which is = 180 degrees. Because the y degrees are the same variable (y) they are equal degrees. All you need to do to find y is 180-35 =145. Divide that by 2 to find both y’s. 145 / 2 = 72.5. You can do the same for x, or realize that x and 35 are alternate interior angles, meaning they are the same measure: 35 degrees.

5x +2(x3 - 9) = 132 + 8x?

Answers

Answer:

x = 50

Step-by-step explanation:

5x + 2(3x - 9) = 132 + 8x

5x + 6x - 18 = 132 + 8x

11x - 18 = 132 + 8x

11x - 18 = 8x + 132

11x - 18 + 18 = 8x + 132 + 18

11x = 8x + 150

11x - 8x = 8x - 8x + 150

3x = 150

3x ÷ 3 = 150 ÷ 3

x = 50

Equation of the line in point-slope form: y - 5 = -⅚(x - 2)

Equation of the line in slope-intercept form: y = -⅚x + 20/3

Step-by-step explanation:

Equation of a line can be expressed in the point-slope form as y - b = m(x - a), where,

m = slope = -⅚

a = 2

b = 5

Substitute the values into y - b = m(x - a):

y - 5 = -⅚(x - 2) => point-slope form.

We can rewrite this in the slope-intercept form, such as:

Multiply both sides by 6

6(y - 5) = -5(x - 2)

6y - 30 = -5x + 10

6y - 30 + 30 = -5x + 10 + 30

6y = -5x + 40

Divide both sides by 6

y = -5x/6 + 40/6

y = -⅚x + 20/3

The measure of two consecutive angles of a parallelogram are in the ration of 7:5. What is the measure of the obtuse angle of the parallelogram.​

Answers

Consecutive angles in a parallelogram are supplementary angles which when added together equal 180 degrees.

The ratio is 7:5 so we would have:

7x + 5x = 180

Simplify:

12x = 180

Divide both sides by 12:

X = 15

So one angle is 7 x 15 = 105 degrees

The other angle is 5 x 15 = 75 degrees

An obtuse angle is an angle greater than 90 degrees.

The obtuse angle would be 105 degrees.

Find the area (in square feet) of a trapezoid with height h and bases b_1 and b_2. h = 6 in b_1 = 9 in b_2 = 12 in The area is _ square feet

Answers

Answer:

Area of the trapezoid = 90 square feet

Step-by-step explanation:

Area of a trapezoid with bases b₁, b₂ and height h is given by the formula,

Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

By substituting the given values in the formula,

                   Area = [tex]\frac{1}{2}(6+9)12[/tex]

                            = [tex]\frac{180}{2}[/tex]

                            = 90 square feet

Therefore, area of the trapezoid = 90 square feet
