Hey there! :D
Since 50% is half of 100%, it would also be half of 42.
42/2 <== that can be used to determine 50%
42/2= 21
50% of 42 is 21.
You could also use this:
42*.5= 21 <== this also works
I hope this helps!

Answer:
sqrt(97)
Step-by-step explanation:
Since the x for both of the points are the same, we can reduce the problem to "find the distance between (-4, 7) and (5, 3)".
To do that, we can use the Pythagorean theorem, where <em>(change in x)^2+(change in y)^2 = (distance)^2:</em>
(5-(-4))^2+(3-7)^2=d^2
(9)^2+(-4)^2=d^2
81+16=d^2
97=d^2
d=sqrt(97).
Answer:
x=1, y=-5
Step-by-step explanation:
Given equations are:
In order to solve the equation
Multiplying Eqn 1 by 5 and eqn 2 by 3 and subtracting them
So,
Eqn 1 becomes
15x+50y=-235
Eqn 2 becomes
15x-21y=120
Subtracting 2 from a
15x+50y - (15x-21y) = -235-120
15x+50y-15x + 21y = -355
71y = -355
y = -355/71
y =-5
Putting y= -5 in eqn 1
3x+10(-5) = -47
3x -50 = -47
3x = -47+50
3x = 3
x = 3/3
x = 1
Hence the solution is:
x=1, y=-5
My teachers taught me a trick make a C from the top to bottom
so 5 1/2 would be
5 times 1 + 2 so denominator stays the same so it 7/2.
bottom one is 22/4
make a C from top to bottom and multiply outer number to top add the bottom to that then keep denominator the same.
Hope i helped.
