X-5=40 x=45 can I get the crown?
Answer:
The coordinates of A would be (-1, 2)
Step-by-step explanation:
In order to find this, use the mid-point formula.
(xA + xB)/2 = xM
In this, the xA is the x value of point A, xB is the x value of point B, and xM is the x value of M. Now we plug in the known information and solve for xA.
(xA + 5)/2 = 2
xA + 5 = 4
xA = -1
Now we can do the same using the midpoint formula and the y values.
(yA + yB)/2 = yM
(yA + 10)/2 = 6
yA + 10 = 12
yA = 2
This gives us the midpoint of (-1, 2)
Answer:
12
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 9^2 = 15^2
a^2 +81 =225
Subtract 81 from each side
a^2 = 225-81
a^2 = 144
Take the square root of each side
sqrt(a^2) = sqrt(144)
a=12
Step-by-step explanation:
<h3>Vocabulary (what the words mean):</h3>
Divide, the same as ÷
divide 6 <u>by</u> 3
<u>by</u> is the same as the symbol
6 ÷ 3 = 2
Difference, This is another way of saying take away or minus
the difference of 6 and 3 is
6 - 3 = 3
Product, This is another word for multiply or times
the product of 2 and 3 is
2 × 3 = 6
<h3>Write as an equation</h3>
divide <em>(÷)</em> the difference of 20 and 6 <em>(20 - 6)</em> <u>by</u> the product of 7 and 2 <em>(7 × 2)</em>
<em />
<em>so </em>
<em>(20 - 6) ÷ (7 × 2)</em>
<em />
<em>can you do the rest???</em>
