Are the answers rounded to the nearest tenth?

[] 10x + 4

(5x) + (2x + 5) + (3x - 1)

5x + 2x + 3x + 5 - 1

10x + 4

[] 4x + 4

Bottom: (1/2) * (3x -1) = 1/2x - 1/2

Left side: (1/2) * (5x) = 5/2x

Right side: (1/2) * (2x+5) = x + 5/2

\/

Add them together:

(x + 5/2) + (5/2x) + (1/2x - 1/2)

x + 5/2x + 1/2x + 5/2 - 1/2

4x + 4

[] The Triangle Midsegment Theorem (midsegment = 1/2 times triangle base) and then calculated by adding the three midsegments together.

     Hope this helps and is correct, have a nice day! :D

check attached file for a diagram I made

     Note: I realized after it was made I did the midsegment wrong so ignore that part! It should be a triangle with the three points in the middle of the sides.

Answer:

-4 - 20z sorry if I'm wrong

Answer:

500

Step-by-step explanation:

Out of every 15 people, there are 12 people who prefer eating at restaurants which means that 80% of people (12/15=.8) prefer eating out.

If 400 selected eating at restaurants in a survey, this accounts for 80% of the people that voted.

We can simplify this now to 20%=100 people because 80% is also four-fifths of 100% and the remaining one-fifth will equal 100 people. (400/4=100)

Since the remaining 20% is 100 people, we can do 400+100= 500 people that participated in the survey.

Answer:

4/3 or 1  1/3

Step-by-step explanation:

Answer:

4/3 or 1and1/3

Step-by-step explanation:

To find the slope, all we need to do is plug in both coordinates into the slope formula and the result will be the slope.

the slope formula is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

to make it easier, we can label each x and y as x2, x1, y2, and y1 (it really doesn't matter which y or x value is the one as long as they are from the same pair like (4,3) can be x1 and y1 but can't be x2 and y1)

(4,3) (x1,y1)            (1,-1)  (x2,y2)

so just plug it into the formula and solve:

[tex]m=\frac{-1-3}{1-4} =\frac{-4}{-3} =\frac{4}{3} or 1\frac{1}{3}[/tex]

Answer:

The inside angles of a pentagon add up to 540 degrees. The four given angles add up to 433 which means that the interior angle that remains unknown is 107 degrees. That means that the measure of angle a is 73

Answer:

axis of symmtery: x = 3 or h = 3

Step-by-step explanation:

The vertex (h, k) of a parabola is the point wherein the graph intersects the axis of symmetry—the imaginary straight line that bisects a parabola into two symmetrical parts, where x = h.

Regardless of whether the quadratic equation is in standard or vertex form, the x-coordinate (h) of the vertex determines the axis of symmtetry, hence, x = h.

Therefore, given that the vertex of a parabola is at point (3, 5), then it means that the axis of symmetry occurs at x = 3 or h = 3.

=======================================================

Explanation:

The triangle is scalene because all three sides are different in length. Also, the angles are all different which is another piece of evidence of this.

The triangle is a right triangle because of the 90 degree angle. Often the term "right angle" is used in place of "90 degree angle".

Answer:

78° +78°+3x-12= 180 {being isosceles triangle and sum of 3angles of a triangle is 180°}

156+ 3x-12=180

144+3x=180

3x=180-144.

3x=36

Answer:

Segment RW congruent to segment XY

Step-by-step explanation:

SAS means side-angle-side.

You are given two congruent angles, so you already have the angle you need for SAS.

By the reflexive property, side XW is congruent to itself, so now you have a side also.

You need another pair of sides, but the two sides must include the angle.

Answer: Segment RW congruent to segment XY

first lets change this problem into an equation...

0.09*x+0.15*3000=0.12(x+3000)

Step 1: Simplify both sides of the equation.

0.09x+(0.15)(3000)=0.12(x+3000)

0.09x+(0.15)(3000)=(0.12)(x)+(0.12)(3000)

0.09x+450=0.12x+360

Step 2: Subtract 0.12x from both sides.

0.09x+450−0.12x=0.12x+360−0.12x

−0.03x+450=360

Step 3: Subtract 450 from both sides.

−0.03x+450−450=360−450

−0.03x=−90

Step 4: Divide both sides by -0.03.

-0.03x/-0.03=-90/0.03
