Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

y = -1/2x + 7

6 = -1/2(2) + 7

6 = -1 + 7

6 = 6

y = 8x - 10

6 = 8(2) -10

6 = 16 - 10

6 = 6

Answer:

19/15

Step-by-step explanation:

To solve this, we need to add 2/3 and 3/5, to do this, we need to find the LCM of 3 and 5, that is 15. We multiply 2/3 by 5/5 and 3/5 by 3/3. This gets us 10/15 + 9/15. When we add those together, we get 19/15.

Answer:

9/15+10/15

19/15

Call the four people [tex]abc[/tex] and [tex]d[/tex].

We know:

[tex]\frac{a+b+c}{3}[/tex][tex]=42[/tex]

and

[tex]\frac{a+b+c+d}{4}[/tex][tex]=40[/tex]

Thus:

[tex]a + b + c = 126[/tex]

[tex]\frac{126+4}{4} = 40[/tex]

[tex]126 + d =160[/tex]

[tex]d = 34[/tex]

Answer:

im guessing D sorry if wrong

Answer: D

Step-by-step explanation:

Since the scale factor is 4:1, you need to divide each side by 4.

10 / 4 = 2.5

12 / 4 = 3

Also you can clearly rule out answer choices b and c because they just don’t make since since the object is smaller than the scale drawing.

Answer:

4 + 29 ≥ 26.

Step-by-step explanation:

I'm assuming you want me to make an inequality with this, so I will do that. Since sum means to add, we write this: 4 + 29. At least can translate to greater than or equal to, we can write that symbol as ≥. Now, let's write the whole inequality, we can write it as 4 + 29 ≥ 26.

Answer:

Pythagorean theorem, stating that every right triangle has side lengths satisfying the formula a2 + b2 = c2; thus, Pythagorean triples describe the three integer side lengths of a right triangle. However, right triangles with non-integer sides do not form Pythagorean triples.

Answer:

The percent of the increase for the money the class raised is 10 %

Step-by-step explanation:

Because if you divide 1500 by 10 you get 150 that means 150 is 10 % of 1500 and if you add 150 to 1500 you get 1650 so the increase of money the class raised is 10 %

Answer:

h = $4 a hotdog

c = $2 bag of chips

Step-by-step explanation:

3h + c = 14

2h + c = 10

3h + c = 14

-2h - c = -10

h = $4 a hotdog

2(4) + c = 10

8 + c = 10

c = $2 bag of chips

Answer:2+ 3/5x

Step-by-step explanation:

(2⁵ * 8⁴) / 16

= [2⁵ * (2³)⁴] / 16

= (2⁵ * 2¹²) / 2⁴

= 2¹⁷ / 2⁴

= 2¹³.

Hence a = 3, b = 12 and c = 13.

Answer:

5,15

Step-by-step explanation:

For mixed fractions, mutiply the bottom and add the top Ex: 1x4=4 and 4+1=5 hence 1 1/4 being 5/4 and the second you just mulitply. 3X5=15 4X5=20 or 15/20.

Step-by-step explanation:

2.5 hours = 150 min

1/3 of 150 is 50 min, which means she spent 50 min on her history project = 100 min leftover

3/5 of 100 min is 60 min (1 hour) = 40 min leftover

She spent 40 min writing her essay

Answer: percent of the people surveyed that were satisfied with the​ car= 55%

Step-by-step explanation:

Step 1

Total Number of people in the survey who owned certain type of car = 3,500

Number of people that would buy that type of car again = people surveyed that were satisfied with the​ car= 1,925

Step 2

Percentage of people satisfied with the  car=  people surveyed that were satisfied with the​ car/Total Number of people in the survey who owned certain type of car  x 100

=1925 / 3500 x 100

=0.55 x 100

=55%

Answer:the answer is NO.

Answer:

Not sure how you would word it but the bigger triangle is 2 times larger than DEF.

Step-by-step explanation:

DE=4

AE=4

4+4=8

AD=8

Hope this helps!!

The scale factor used to create DAB from triangle DEF is 2.

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

The length of the base of the triangle DEF is 4 units and of DAB is 8 units.

The length of the height of DEF is 3 units and that of DAB is 6 units.

From this, we conclude that the scale factor is 2 as 8 is a multiple of 2×4 and 6 is a multiple of 2×3.

Answer:

y-intercept: 5

slope: 1/2

Step-by-step explanation:

The equation y=1/2x+5 is an example of y-intercept form(y=mx+b). This is where b represents the y-intercept and m represents the slope. I will not graph this for you but can explain it.

First plot the y-intercept on the graph. (0.5). Then use the slope to find the next point off of the y-intercept. So for example, the next point would be (2,6).
