The answer is A. If you take that equation and subtract each side of the equal sign by 35 and divided by 15 you’ll get how many hours Anthony worked.
Answer: I think it s 8
Step-by-step explanation:
5 + 7 + 5 + 7 = 24 and 24/3 = 8
Answer:
The correct one is A
Step-by-step explanation:
2x-y=10
y=1/2 × x+5
Now you substitute the value of y into the first equation.
2x - (1/2 × x+5) = 10
Solving this equation for x you get that x=6
Now substitute the value of x any of these two equations, doesn't matter. Let's say we do with the first one.
2×6-y=10
12-y=10
-y=10-12
-y= -2
y=2
And so you've got the first one which is, (x,y)=(6,2)
Answer:
the first one is equal to 61 the next is 32
Answer:
Step-by-step explanation:
Given:
The area 'A' of a circle with radius equal to 'r' is given as:
In order to rewrite the given formula in terms of radius 'r', we need to isolate 'r'.
Dividing both sides by π, we get:
As 
, the above equation becomes:
Taking square root both the sides, we get:
We neglect the negative result while taking square root as the radius can't be a negative number.
Thus, the formula for radius 'r' in terms of area 'A' is given as:
