Does x=5 satisfy the equation 3x + 2 +5x= 95 explain

Answers

Answer 1

Answer:

No

Step-by-step explanation:

3x + 2 +5x

if x=5

3(5)+2+5(5)

=15+2+25

=42 which is not equal to 95

Answer 2

No, it doesn't satisfy the equation

Step-by-step explanation:

3x + 2 +5x = 95

Now putting the value of x

3×5 + 2 + 5×5 = 95

15 + 2 + 25 = 95

42 ≠ 95

Hence, x = 5 doesn't satisfy the equation 3x + 2 +5x= 95

Answer:

x = 41

y = 65

z = 107

Step-by-step explanation:

y and 65 are vertically opposite angles. Vertically opposite angles are equal.

y = 65

74 + y + x = 180

74 + 65 + x = 180

139 + x = 180

x = 180 - 139

x = 41

z is the exterior angle, whereas 66 and x are interior angles in a triangle.

Formula : -

Exterior angle = Sum of two interior angles

z = 66 + x

  = 66 + 41

z = 107


Seventeen lines drawn in a plane, with no three concurrent and no two parallel, divide the plane into
closed regions (bounded on all sides) and open regions. The number of closed regions is

Answers

Answer:

120

Step-by-step explanation:

Make a chart:

Lines:                  0   1    2   3  4   5   6

Closed regions: 0   0   0   1   3   6   10

Find the number of numbers using the formula:

[tex]\frac{first term + last term}{2}[/tex] x 14 = [tex]\frac{2 + 15}{2}[/tex] x 14

                                  = 8.5 x 14

                                  = 119

119 + 1 = 120

(add 1 because we didn't count the first line in the formula)

I hope this helps :)

The total number of closed regions is 120.

Given that,

Seventeen lines are drawn in a plane, with no three concurrent and no two parallel, dividing the plane into closed regions (bounded on all sides) and open regions.

Used the formula to calculate the number of closed regions with n sides is,

Number of sides = (n - 1) (n - 2) / 2

Here, n = 17

Hence, The number of closed regions is,

Number of sides = (n - 1) (n - 2) / 2

Number of sides = (17 - 1) (17 - 2) / 2

Number of sides = 16 × 15 / 2

Number of sides = 120

Please help quick! Find the value of x to the nearest tenth.

Answers

Answer: 3.3

Step-by-step explanation: pythagorean theorem.

first we'll do the bottom triangle. a^2 + b^2 = c^2

a=3 and b=4

(3)^2 + (4)^2 = 9 + 16 = 25 which = c^2

to find c from c^2, square root the c^2 value. in this case it's 25. the square root of 25 is 5.

5 is now the base of the rectangle

now we can do pythagorean theorem again. except we'll switch it so it's c^2 - b^2 =a^2

c=6 and b=5

(6)^2 - (5)^2 = 36 - 25 = 11 = a^2

to find a we'll square root 11 which is just [tex]\sqrt{11[/tex]. approx. 3.3 to the nearest tenth.

Answer:    x = √(11)   or  ≈ 3.3167

Step-by-step explanation:

We can use the Pythagorean theorem to solve for x.

But first, we have to find the value of 'a' (as I labelled in the diagram below). We could actually do all this in one step if we set it up correctly.

so    x = √(6² - a²)

&     a² = 3² + 4²

⇒  x = √[6² - (3² + 4²)]

    x = √(11)   or ≈ 3.3167

what is 5x(2x+7)+x(3x-5 do you know

Answers

Answer:

43xx

Step-by-step explanation:

5x(2x+7)+x(3x-5)

first, do the equations inside the parentheses

2x+7=9x

3x-5=-2x

so,

5x(9x)+x(-2x)

Next, do 5x times 9x

(5x) x (9x) = 45

so,

45+x(-2x)

Next, do x times (-2x)

(x) x (-2x)=-2xx

so,

45+-2xx

=43xx

If Michael made 12 shots out of 18 what is the percentage of shots made by him?

Answers

Answer:

At least 66%

Step-by-step explanation:

65% of 18 is 11.7

67% of 18 is 12.06

Therefore, at least 66% of the shots where made by Michael.

Step-by-step explanation:

100% = 18

x% = 12

x% = 100% / 100 × x

so,

18/100 × x = 12

18x = 1200

x = 1200/18 = 200/3 ≈ 66.66666...

so, he made about 67% of the shots.

What is a strategy for dividing 428 by 107?

Answers

Answer:

4

Step-by-step explanation:

428÷107

Use the 1 st

 digit 4 from dividend 428

107)1

107)428

 

​ Since 4 is less than 107, use the next digit 2 from dividend 428 and add 0 to the quotient

107)02

107)428

 

​Use the 2nd

 digit 2 from dividend 428

107)03

107)428

 

Since 42 is less than 107, use the next digit 8 from dividend 428 and add 0 to the quotient

107)004

107)428

 

Use the 3rd

 digit 8 from dividend 428

107)005

107)428

 

​ Find closest multiple of 107 to 428. We see that 4×107=428 is the nearest. Now subtract 428 from 428 to get reminder 0. Add 4 to quotient.

107)0046

107)428

 107)428

 107)9990

 Since 0 is less than 107, stop the division. The reminder is 0. The topmost line 004 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.

Quotient: 4

Reminder: 0
