Please solve i need help.

Answer:

40 mph

Step-by-step explanation:

s = d/t

a to b's distance = 180 miles

7:30 - 12pm = 4.5 hours (time)

speed = 180 ÷ 4.5

speed = 40

Step-by-step explanation:

A. to make the quadrilateral a parallelogram, we have:

7y + 5 = 8y - 4

112 = 10x - 8

<=> y = 5 + 4

120 = 10x

<=> x = 12

y = 9

B.we have:

17 = 4x + 5

63 = 8y - 1

<=> 12 = 4x

64 = 8y

<=> x = 3

y = 8

Answer:

y=-3/2x+1

Step-by-step explanation:

-3/2 is the slope

1 is the y intercept

Answer:

A = ( 1 , 2 )

B = ( 4 , 11 )

C = ( 6 , 4 )

D = ( 10 , 9 )

Answer:

A. (1,2), B. (4,11), C. (6,4), D. (10,9)

Step-by-step explanation:

A. On the x line, it is 1 so the number is (1, ?). On the y-line it is 2 so the point is (1,2)

B. On the x line,  it is 4 so the number is (4,?). On the y-line, it is 11 so the point is (4,11).

C. On the x line, it is 6 so the number is (6,?). On the y-line, it is 4 so the point is (6,4).

D. On the x line, it is 10 so the number is (10,?). On the y-line, it is 9 so the point is (10,9).

Answer: Try 5/8

Step-by-step explanation: Because 1/2 and 3/4 can also be written as 4/8 and 6/8. And that's how I got 5/8.

Hi! I believe that I have the answer.

My answer: 5/8.

1/2 can also be put as 4/8. 3/4 can also be put as 6/8. Right in the middle of 4/8 and 6/8 is 5/8.

I hope that helps!

Answer:

The y intercept is kinda in the middle but if it was approximate then probably 4 and the equation would be y= 1x +4

Step-by-step explanation:

The y intercept is 4 because that where the line hits on the y axis and the x would be 1 because it goes up one and over one to the next dot. If i were to guess i think how many months for 13 matches it might be around 3 but sry if that's not right

Answer: 6.8

Step-by-step explanation:

Add all of them, and then divide them by 8

Answer:

The mean is 6.75

Step-by-step explanation:

There are 8 numbers in the set. Add them all, and then divide by 8.

2 + 5 + 5 + 6 + 8 + 8 + 9 + 11 / 8=54/8=6.75

So, the mean is 6.75!

Hope this answer helps!

Answer:

50%

Step-by-step explanation:

Analyise the data, and you can figure it out.

Answer:

y = mx + b is slope intercept form

Y - y1 = m(x - x1) is slope point form

Ax + Bv = C is standard form

Answer:

V≈234.57

Step-by-step explanation:

This is the correct answer, try it!

--Answer--

1. 4

2. 6

3. 14

4. 9

5. 10

6. A

7. 20

--Explanation--

1. The lower quartile is always the left side of the box.

2. The IQR is Quartile 1 minus Quartile 2, so you could subtract the number at the right of the box with the left.

3. The range is the highest number minus the lowest number. (The numbers that stretch out all the way til the lines stop)

4. The median is the line in the middle of the box.

5. The upper quartile is right of the box. (the vertical line)

6. The Lower Quartile Is Always Smaller Than The Upper Quartile.

7. The number all the way to the right of the number line.

Sorry if anything is incorrect, but I hope it helps :>

Answer:

6.67<-8

Step-by-step explanation:

-4(r- 2/3) +4= 20/3

20divided by 3 =6.666666667 which rounds to 6.67

6.67 < -8

Hope this is helpful! :)

Answer:

See explanation for answer.

Step-by-step explanation:

−4(r−2/3)+4<−8

−4r+20/3<−8

−4r+20/3−20/3<−8−20/3

−4r<−44/3

−4r/−4<−44/3/−4

Answer: r>11/3

I hope this helps!

Have a lovely day!

4. she used 2.5 meters per bow

Answer: t = 33

Step-by-step explanation:

t + 5 = 38

    -5   -5      subtract 5 from both sides in order to isolate t

t = 33

Answer:

4/10 which simplifies to 2/5 or 40%

Answer:

1. 0.5,4.5

2. 1.5,2

3. 4,4.5

Step-by-step explanation:

The sun is in the middle of both numbers, and there is a 1 gap, So we make it 1/2. To do that for each problem you add 0.5 for each answer in the middle.

Answer:

Option 3, angle 2 is equal to 37 degrees

Step-by-step explanation:

Angle 2 is on the opposite side of the 37 degree angle, so it is also 37 degrees

Answer: Not enough information is given

Step-by-step explanation:

Data: Angle 4 is 37 degrees

Angle 1 is x degrees

Angle 2 is x degrees

Angle 3 is x degrees

It only shows us that the 1 and 3 or obtuse and 2 is acute

We don't know if the angles are Congruent so we cannot draw a conclusion about the size of any of the other angles

Step-by-step explanation:

Answer: (4)

Step-by-step explanation:

At step 2 the student rewrites 6 as 2*(4), and 8x as 2*(6x). This is incireect, since 2*(4) is actually 8, and 2*(6x) is 12x.

The correct way to do it is to rewrite 6 as 2*(3), and rewrite 8x as 2*(4x), which corresponds to the answer option (4)

Answer:

5 + 2x = 27

Step-by-step explanation:

Five more than twice a number is 27 is 5 + 2x = 27

Answer:

s = 16

Step-by-step explanation:

[tex]\frac{s}{4} +12=16[/tex]

step 1 subtract 12 from each side

12 - 12 cancels out

16 - 12 = 4

now we have [tex]\frac{s}{4}=4[/tex]

step 2 multiply each side by 4

[tex]\frac{s}{4} *4=s[/tex]

4 * 4 = 16

we're left with s = 16
