Answer:
R(-7,0)Step-by-step explanation:
Let the midpoint of PR be Q(-1,3) where P is (5,6). To get the other coordinate R, we will use the midpoint formula as shown;
Q(X,Y) = {(x₁+x₂)/2, (y₁+y₂)/2}
From the formula;
X = (x₁+x₂)/2 and Y = (y₁+y₂)/2
From the coordinates given, X = -1, Y = 3, x₁ = 5 and y₁ = 6. To get x₂ and y₂, we will substitute the given points into the expressions above;
To get x₂;
X = (x₁+x₂)/2
-1 = (5+x₂)/2
cross multiply
-1*2 = 5+x₂
-2 = 5+x₂
subtract 5 from both sides
-2-5 = 5+x₂-5
x₂ = -7
Similarly to get y₂
Y = (y₁+y₂)/2
3 = (6+y₂)/2
cross multiply
3*2 = 6+y₂
6 = 6+y₂
subtract 6 from both sides
6-6 = 6+y₂-6
y₂ = 0
Hence the coordinate of R(x₂, y₂) is (-7,0)

The probability that an event will happen is P(E)=
34/41.
Find the probability that the event will not happen.
Answer:
7/41
Step-by-step explanation:
There is a 34/41 probability that this event will happen so to find the probability of which the event will not happen, the subtract 34 from 41 to get your answer.
41-34=7
Therefore, 7/41 is the answer.
Ps. is the P(E) included in the main question? if it is, the the answer might differ from the one I am giving you.

Isolate the variable by dividing each side by factors that don't contain the variable.
which value for x makes the sentence true? 1/40 + x = 1/8
Answer:
x = 1/10
Step-by-step explanation:
1/40 + x = 1/8
Subtract 1/40 from each side
1/40-1/40 + x = 1/8-1/40
x = 1/8 - 1/40
Get a common denominator
x = 1/8 *5/5 - 1/40
x = 5/40 - 1/40
x = 4/40
Simplify
x = 1/10
If g(x) = 3x^2+2x-1. Find g(-1).

Find the area of a square with a side of length 2 Square root of 3+6 square root of 7 inches
Answer:
(264+24√21) in²Step-by-step explanation:
Area of a square = Length * Length
A = L²
Given the length of a square as [tex]2\sqrt{3}+6\sqrt{7}[/tex] inches' The area of the square will be calculated as shown;
[tex]A = (2\sqrt{3}+6\sqrt{7})^2\\\\A = (2\sqrt{3}+6\sqrt{7})(2\sqrt{3}+6\sqrt{7})\\\\A =(2\sqrt{3})(2\sqrt{3})+(2\sqrt{3})(6\sqrt{7})+(6\sqrt{7})(2\sqrt{3})+(6\sqrt{7})(6\sqrt{7})\\\\A = 4\sqrt{9}+12\sqrt{21}+12\sqrt{21}+36\sqrt{49}\\\\A = 4(3)+24\sqrt{21}+36(7)\\ \\A = 12+24\sqrt{21}+252\\\\A = 264+24\sqrt{21}[/tex]
Hence the area of the square is (264+24√21) in²

Which statement is true?
A. 3 2/5 < 2 4/5
B. 2/3 > 1 7/3
C. 4 1/4 > 2 3/4
D. 1/2 < 1/4
Answer: C. 4 1/4 > 2 3/4
Step-by-step explanation: Option C is correct because when comparing mixed numbers, we first compare the whole numbers. In this case, 4 is greater than 2. Then, if the whole numbers are the same, we compare the fractions. In this case, 1/4 is greater than 3/4. Therefore, 4 1/4 is greater than 2 3/4.

I need to know what x is and if you could put the steps that could be really helpful (THANK YOU)
Step-by-step explanation:
Hey there!!!
Here,
Triangle BCM and triangle ABC are 2 isosceles triangle.
Solving in triangle BCM.
Angle CBM = 31° { it is the base angle.}
Angle CBM + 31° + angle BCM = 180° { sum of interior angle of a triangle is 180°}.
31°+31°+ angle BCM = 180°
Angle BCM = 180° - 62°
Therefore the measure of angle BCM = 118°.
Again,
Solving in triangle ABC.
Angle BCM + angle ACB = 180° { being linear pair}.
118°+ angle ACB = 180°
Angle ACB = 180°-118°
Therefore the measure of angle ACB is 62°.
Angle ACB = angle BAC (Base of an isosceles triangle).
Therefore the measure of angle BAC = 62°.
Now, To find x,
Angle BAC + angle ACB + angle x = 180° (sun of interior angle of a triangle is 180°).
62°+62°+angle x = 180°
Therefore the measure of angle x is 56°.

If I spent $3.87 on grapes at Tom Thumb and I bought 3.05 pounds. How much was each pound?
(round to the nearest hundredths place because it is money)
Answer:
$1.26 or $1.27 depending on whether you round up or down. The number in the thousandths is an 8 though
Step-by-step explanation:
You would divide 3.05 by itself to get one pound
and then 3.87 by 3.05. You have to divide both numbers so you get the number for one pound.
3.87÷3.05=1.268852459
Round up or down depending on what your teacher would want you to do so that the decimal is in the hundreths like money.
