Given: a = 12, c = 38, find b. (Round answer to the nearest tenth.)

Answer:

12 bicycles

5 tricycles

Step-by-step explanation:

[tex]x + y = 17\\2x + 3y = 39\\\\2x + 2y = 34\\2x + 3y = 39\\\\y = 5\\\\2x + 2 * 5 = 34\\2x + 10 = 34\\2x = 24\\x = 12[/tex]

Answer: 49°F

Step-by-step explanation: x - 12 = 37, So all we have to do is reverse it. That means we add 37 and 12 to get the beginning temperature. 37 + 12 = 49. So at the beginning of the evening, it was 49°F.

Answer:

580 seedlings altogether.

Step-by-step explanation:

Given that,

Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.

The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%

Let x = the total number of seedlings

[tex]15\%\ of\ x=87\\\\x=\dfrac{87\times 100}{15}\\\\x=580[/tex]

Hence, three boys plant 580 seedlings altogether.

Answer:

Step-by-step explanation:

5.

 2x  =  20   ⇒    x = 10

5y + 5 = 35   ⇒  5y = 30   ⇒  y = 6

6.

m∠T = x = 180° - 90° - 30° = 60°

m∠E=m∠T   ⇒    y = 180° - 90° - 60° = 30°

m∠B = m∠L = q = 180° - m∠E = 180° - 60° = 120°

m∠B = 30° + p + y  ⇒  p = 120° - 30° - 30° = 60°

Answer:

The slope of the line is un-defined

Step-by-step explanation:

Explanation:-

Given points are ( -10 , 4) and (-10 ,8)

Slope of the line

 [tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]m = \frac{8-4 }{-10-(-10}) = \frac{4}{-10+10} = \frac{4}{0}[/tex]

m = ∞

The slope of the line is un-defined

Answer:

y=4/3x-5

Step-by-step explanation:

4x-3y=15

-4x      -4x

______________

y=4/3x-5

Answer:

2/3

Step-by-step explanation:

Answer:

4/6 or 2/3

Step-by-step explanation:

1/2 is equivalent to 3/6

3/6 + 1/6 is 4/6

4/6 simplified is 2/3

Answer:

x=2

4-8=-4

-4(-4)=-16

-16-(-4)=-10

Answer:

C) 8

Step-by-step explanation:

Use the formula

Slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]y_1[/tex] - any y value

[tex]x_1[/tex] - x value corresponding to y_1

similarly, you can pick y_2 and x_2 from the table.

Pick any two rows

Let's pick row 3 and 4

Slope = [tex]\frac{33-23}{5-3}[/tex]

=> 10/2

Slope = 5

Now formula

y = slope * x + intercept

y = 5x + intercept

intercept =  y - 5x

Now take any row from the table and substitute above to calculate intercept

Taking row 3

intercept  = 23 - 5 * 3

intercept = 8

Answer:

7 2/3 or 7.666

Step-by-step explanation:

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

since we only have two points we have to do

4/3 x 23/4 = 7 2/3 or 7.666

so the answer is 7 2/3 or 7.666

Answer:

where u getting it from?

Step-by-step explanation:

Answer:

needs a little more so i can answer?

Step-by-step explanation:

Answer:

2/3

Step-by-step explanation:

you can set it up as x/y because it varies directly

so when y=6 x=72

72/6 = 12

so x will always be 12 times greater than y

x=12y

so if x=8

8=12y

y=8/12

y=2/3

Answer

5 and 6

Step-by-step explanation:

First | Find the square root of √30 (Put it in the calculator)

Answer | 5.47722557505...

Second | Round the number to the tenths

Anwer | 5.5 (ect the number in the hundreths place is greater than 5 so you bump up the 4 by 1 so 5.4 to 5.5)

Third | Get a line and see where 5.5 belongs it cant be 4 and 5 since the answer will need to be 4 or 5.0

Concusion | Here are the steps to find the answer hope this helped!

Answer:

-2/4 = w

Step-by-step explanation:

4w + 2 when you isolate the variable, you subtract the 2, then you have to divide by 4 so that would give you -2/4  = w.

Answer:

i am calculating it for u

Step-by-step explanation:

Answers:

x= -10 and y= 16

3y = -6x - 12

3y = -6(-2y+22) -12

3y = 12y - 144

3y + -12y = 12y -144 + -12y

-9y = -144

divide -9 on both sides

y= 16

x= -2y+22

x= -2y+22

x= (-2)(16)+22

x= -10
