Answer:
The mid point of ST is (1,5) and ST = 10 units
Step-by-step explanation:
It is given that,
S(-3,2) and T(5,8). We need to find the coordinates of the midpoint of ST and also ST.
Let (x,y) be the mid point of ST. Using mid-point formula we get :
[tex](x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
We have, x₁ = -3, x₂ = 5, y₁ = 2 and y₂ = 8
So,
[tex](x,y)=(\dfrac{-3+5}{2},\dfrac{2+8}{2})\\\\(x,y)=(1,5)[/tex]
(1,5) is the midpoint of ST.
Using distance formula to find ST as follows :
[tex]ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\ST=\sqrt{(5-(-3))^2+(8-2)^2} \\\\ST=10\ \text{units}[/tex]
Hence, the mid point of ST is (1,5) and ST = 10 units.

which expression can be used to solve 3/5 ÷ 7/10
Answer:
Step-by-step explanation:
3/5 divided by 7/10
You use KCF
KCF stands for keep change flip
So it would be 3/5x10/7
3 10 15
_ x _ = _
5 7 7
you need to simplify it so the 5 in 3/5 would be a 1 and the 10 in 10/7 would be 5

Please help this sat math problem got me stumped
Answer:
option A
Step-by-step explanation:
[tex]3x-y=12\\ =>3x = 12+y\\=>x=\frac{y+12}{3}[/tex]
Putting the value of x in [tex]\frac{8^{x} }{2^{y} }[/tex] gives :-
[tex]\frac{8^\frac{y+12}{3} }{2^y} = \frac{2^3(\frac{y+12}{3} )}{2^y} = \frac{2^{y+12} }{2^y} = 2^{y+12-y}=2^{12}[/tex]

3x-2(x+3)=4x-9-x is the question
Answer:
[tex]\large\boxed{x = 7}[/tex]
Step-by-step explanation:
3x - 2(x + 3) = 4x - 9 - x
Start by multiplying 2 by the values in the parenthesis
3x - 2x + 6 = 4x - 9 - x
Subtract 3x - 2x and 4x - x
x + 5 = 3x - 9
Add 9 to both sides of the equation
x + 14 = 3x
Subtract x from both sides of the equation
14 = 2x
Divide both sides of the equation by 2
[tex]\large\boxed{x = 7}[/tex]

(5x+2) = 32 what is the value of x ?
Answer:
x=6
Step-by-step explanation:
5x+2=32
Step 1: Subtract 2 from both sides.
5x+2−2=32−2
5x=30
Step 2: Divide both sides by 5.
5x
5
=
30
5
x=6
Answer:
x = 6
Step-by-step explanation:
5x + 2 = 32
Subtract 2 from both sides
5x + 2 - 2 = 32 - 2
5x = 30
Divide both sides by 5
5x/5x= 30/5
x = 6

Find the distance of LINE SEGMENT rs.
Answer:
11
Step-by-step explanation:

A rectangular garden is 6 feet longer than its wide. The perimeter of it is 52 feet. What equation can be used to find the width?
Answer:
Hi there!
Your answer is;
the equation
(w+6)+(w+6)+(w)+(w) = 52
The width of this rectangle is 10. The length of this rectangle is 16.
Step-by-step explanation:
Rectangular perimeter:
l+l+w+w
l= w+6
w= w
(w+6)+(w+6)+(w)+(w)
4w+12= 52
4w = 40
/4
w= 10

∠A and ∠B are vertical angles. If m∠A=(3x-30)° and m∠B=(2x-9)°,then find the value of x.
Answer:
x = 21
Step-by-step explanation:
Vertical angles are congruent, thus
∠ A = ∠ B , substitute values
3x - 30 = 2x - 9 ( subtract 2x from both sides )
x - 30 = - 9 ( add 30 to both sides )
x = 21
Hello there! :)
[tex]\huge\boxed{x = 21}[/tex]
Vertical angles are congruent, therefore:
∠A ≅ ∠B
3x - 30 = 2x - 9
Subtract 2x from both sides:
3x - 2x - 30 = 2x - 2x - 9
x - 30 = -9
Add 30 to both sides:
x - 30 + 30 = -9 + 30
x = 21.
