The equation you had:
6x + 5y = 45
Solve for Y:
5y = (-6x) + 45 divide by 5
y = (-6/5)x + 9
y = -1 1/5x +9
The answer is 15
these chords are congruent because the radius of the circle are perpendicular to the them
so we can find EF by making an equation:

so EF is = 3(15)+5=50
good luck
There are 36 inches in a yard. 36*6.75 =243. 6.75 yards is the same as 243 inches.
To know the angle measure between the vertices, you divide 360° by 3. Option C
<h3>Interior angles of a hexagon</h3>
Formula for interior angles of polygon is given as;
= ( n -2 ) × 180 degrees
Hexagon has 6 sides, n = 6
= ( 6 - 2 ) × 180° = 4 × 180° = 720°
Each interior angle = 720/ 6 = 120
To get 120 from 360
= 
= 
Thus, to know the angle measure between the vertices, you divide 360° by 3. Option C

Here is an example of how to do it⬇️
Set variables for the quantities we want to find.
Let x = number of apples
Let y = number of oranges
Next, we use these variables to write equations that describes the whole story.
Since the total price is $7.75 and each type of fruit has their own price, we can say
0.40x + 0.35y = 7.55
The other equation will represent the total number of fruits bought all together, as Mark mentioned. Once you have those equations, you solve the system using substitution and elimination methods to solve for the variables x and y.
(If x represents the number of peaches purchased and y represents the number of mangos purchased)
Sorry if this isn’t good explanation but I tried sorry goodluck!
