Answer: 2.6
Step-by-step explanation:
PQ = QR (because it’s a rhombus), so
9b - 5 = 3b - 0.8
b = 0.7
And RS = PQ (again because rhombus), so RS = 9b - 5 = 1.3. Since RT is twice RS, we have
RT = 2(1.3) = 2.6.

Step-by-step explanation:
The formula to find the area of a circle:
, where
is the radius.
The formula to find the circumference (perimeter) of a circle:
, where
is the radius.
1) To find the circumference of the circle, we need to find the radius (
) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.
Cancel the

where's the graph??
I can't answer this without the graph
Answer:
yes
Step-by-step explanation:
Solving the 2 equations to find the point of intersection
y = 3x - 1 → (1)
y = - x + 3 → (2)
Since both equations express y in terms of x, equate the right sides
3x - 1 = - x + 3 ( add x to both sides )
4x - 1 = 3 ( add 1 to both sides )
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting x = 1 in (2)
y = - 1 + 3 = 2
Thus (1, 2) is the point of intersection
