There is no attached picture, but I guess it is like the one I attached.
If so, the first thing is finding the side measure:
Now, radius is half this measure: 15 in.
And circle area is:
Answer:
Betty = $600
Step-by-step explanation:
3/4 of Alice's salary is the same as 1/2 of Betty's salary
(3/4)a = (1/2)b
multiply both sides by 2
(3/2)a = b
Alice earns $200 less than Betty
b - a = 200
Substitute for b
(3/2)a - a = 200
(1/2)a = 200
multiply both sides by 2
a = 400
b = (3/2)400
b = 600
Answer:
x = 16
Step-by-step explanation:
I could be wrong so sorry in advance lol but this is what I did:
I made the equation 3x + 3 = ((7x-10)/2)
I divided the 2nd equation by 2 so that it would be the same length as RZ.
after that, I got: 3x + 3 = 3.5x - 5
from there, i did basic algebra to get the answer 16
hope this helps!
Answer:
13
Step-by-step explanation:
To find the determinant you subtract the the leading diagonal from the non-leading diagonal.
(4x-2)-(-7x3)
-8 - -21
NB A negative beside a negative gives you a positive number.
-8+21
=13
