The answer is 675 if you don't know standard then you can use lattice.
Let x = the first number
Let y = the second number
So we can set up two equations:
x+y = 400
.8x + .85y = 400-68
Use substitution:
y = 400 - x
.8x + (.85)*(400-x) = 332
.8x + 340 -.85x = 332
8 = .05x
x = 160
So that makes y = 240
We want the decreased values so:
160*.8 = 128
240*.85 = 204
So the answers are 128 and 204
Answer:
60.6
Step-by-step explanation:
The formula for finding the circumference of a circle is C = 2πr
C is circumference, π is pi (we'll just us 3.14 here), and r is radius.
The radius is found by dividing the diameter in half.
19.3/2=9.65
So the equation should look like this:
C = 2(3.14)(9.65)
C = 60.602
C = 60.6
Answer:
5 kilometers south
Step-by-step explanation:
5 kilometers east 5 units right
5 kilometers north 5 units up
5 kilometers west 5 units left
The right and left cancel so we are left 5 units up at this time
we are 5 units north at this time
To get back we must go 5 units down, which is 5 km south
