-2x + 10 +4x=70 (what is X?)

Answer:

a) The triangles are similar, and the ratio of the similar sides are both equal to 1:3. b) the scale factor from triangle abc to def is 3 because if you divide the longer corresponding side length from triangle def by the side of triangle abc, you will get 3. c) x is equal to 7.5 cm. Using the scale factor, you can just multiply 3 by 2.5.

Step-by-step explanation:

a) If you look at the two triangles, you can see that they look similar. Side AB looks similar to side DE, and the side lengths are 1 and 3. Therefore, the scale will be 1:3. b) If you divide the longer corresponding side length from triangle def by the side of triangle abc, you will get 3. c) x is equal to 7.5 cm because the scale factor is 3, which means you have to multiply the smaller side by 3.

Option B is the correct answer, y = 2x + 6

Answer:

A.The slope is 2 and the y-intercept is −6.

Step-by-step explanation:

got it right on the quiz. :)

(hop this helps)

The slope of the line represented by the above equation is:
".2 and the y-intercept is −6." (Option A)

The slope of any line, ray, or line segment in analytic geometry is the ratio of the perpendicular to horizontal distance between any two points on it.

Hence it is correct to state that the slope of the line represented by the above equation [f(t)=2t−6] is: ".2 and the y-intercept is −6."

Answer:

Two times two minus eight

The average pay per week Josh earned for three weeks is $340.

The term average is the sum of all the numbers divided by the total number of values in the set.

Now it is given that,

Pay received in first week = $360

Pay received in second week = $345

Pay received in third week = $315

So,

Total money earned in three weeks = $360+$345+$315

                                                            = $1,020

Now number of weeks  = 3

therefore, average pay per week = Total money earned in three weeks/number of weeks

⇒ average pay per week = $1020/3

⇒ average pay per week = $340

Thus, the average pay per week Josh earned for three weeks is $340.

Answer:

y=3x+18

Step-by-step explanation:

Since slope-intercept form is y=mx+b, we first need to find the slope.

m=y2-y1/x2-x1

m=0-(-9)/-6-(-9)

m=9/3=3

Next we need to find b, or the y-intercept

to do that we plug in numbers to what we already have.

y=3x+b

0=-18+b

b=18

Now we put it all together.

Step-by-step explanation:

7/8 in decimal form is 0.875

Answer:

1) 128°

2) 126°

3) 108°

   The square in the corner means 90°. If you add the interior angles of any triangle together, you get 180. in this case, x is in exterior angle, so you subtract it from 180 to get the interior angle.  

38 + 90 + (180-x) = 180

38 + 90 + 180 - x = 180

38 + 90 + 180 - 180 - x = 0

38 + 90 + 180 - 180 = x

128 = x

again, adding all the interior angles makes 180°. use this to make the equation.

3x + (5x-6) + 90 = 180

3x + 5x - 6 = 90

8x = 96

x = 12.

   x isn't the answer the question wants, however. if you look at the drawing, the angle that's supplementary to 5x-6 is the exterior angle. so,

180 - (5x-6) = the answer

180 - 5x + 6 = the answer

substitute x for 12

180 - 60 + 6 = the answer

126 = x

again, adding all the interior angles together makes 180°.

(a + 10) + 44 + (180-2a) = 180

a + 10 + 44 + 180 - 2a = 180

-a + 234 = 180

234 - 180 = a

54 = a

however, the question is looking for the exterior angle, not a. in this case, the exterior angle is 2a, so just multiply 54 by 2.

x = 108

Step-by-step explanation:

Answer:

64 i think

Simple explanation:

find the missing angle of the triangle with two given angles:

add 36 and 84 to get 120

subtract 120 from 180 and you will get 60

subtract 60 from 90 to find one of the angles in the other triangle

so now you have that the other triangle has an angle of 86 and another angle of 30

add 86 and 30 to get 116

subtract 116 from 180 to get the "? angle"

you should get 64

Another possible explanation:

extend the line that contains the degrees 36 and 84

this will make a third, smaller triangle

this triangle has two measure that are easy to find and that is 96 and 54

when you add those together, you get 150

subtract 150 from 180 to get 30

30 degrees is the measure of the smaller angle at the 90 degrees symbol

now add 30 and 86 together to get 116

subtract that from 180 to get 64
