Answer:
The x coordinate is 2
Step-by-step explanation:
Given
Required
Determine the x coordinate of B
Since B is the bisector of AC, then B is the midpoint and will be calculated using;
Considering the x coordinates alone;
Where
and
Substitute values for x1 and x2
<em>Hence;</em>
<em>The x coordinate is 2</em>
Answer:
If 5 red shirts are added into the box, 7 : 8 is the new ratio.
Step-by-step explanation:
The number of red shirts = 16
Let the number of black shirts = k
Now as the ratio of Red Shirts : Black Shirt = 2 : 3
By RATIO OF PROPORTIONALITY:
⇒
or,
Hence, the number of Black Shirts in the Store = 24
Now, new number pf red shirts = 16 + 5 = 21
So, by the proportionality again, ratio is
Hence, the new ratio of Red shirts : Black Shirts = 7 : 8
Answer:
B. (15, 19)
Step-by-step explanation:
To check to see if a particular ordered pair is a solution to an equation, use the values for the variables and see if the equation is true.
A. 4/5(0) +7 = 7 ≠ 1
B. 4/5(15) +7 = 19 . . . . . . is a solution
C. 4/5(-5) +7 = 3 ≠ 11
D. 4/5(-2) +7 = 27/5 ≠ 1
