Answer: What is the question????
Answer:
49
Step-by-step explanation:
4 : 3
x : 21
ok so we can divide 21 by 3 and get 7.
7 × 4 = 28
4 : 3 = 28 : 21
now we just 28 + 21 = 49 :D
Answer:
14π cm
Step-by-step explanation:
Circumference of a circle given the diameter is :
πd
We simply substitute the value given in the image into our formula to find our answer:
πd = π×14 = 14π
Units will be cm as circumference is a length
This is our final answer as the question states to leave it in pi form .
Hope this helped and brainliest please
A)
The slope-intercept form:

m - slope
b - y-intercept
The formula of a slope:

We have the points (2, 5.1) and (-1, -0.5). Substitute:

Therefore we have:

Put the coordinates of the point (-1, -0.5) ot the equation:

<em>multiply both sides by 2</em>
<em>add
to both sides</em>
<em>divide both sides by 2</em>

Answer: 
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:

Therefore we have:

Put the coordinates of the point (-2, 3) to the equation of a line:

<em>subtract
from both sides</em>
