Answer:
C. d = C/pi
Step-by-step explanation:
lol nothing really to explain but it's saying diameter equals circumference divided by pi
Hope this helps dude !
Sum = adding correct.
That means we need to add 7+5 =12
and add the /8 to it
12/8
But thats improper so we need to simplify.
1 4/8
But theres still some simplifying.
4/8=1/2
That means your answer is 1 1/2
Hope this helped :)
Starting amount = g
Throughout the day 200 pounds is added and 1400 pounds is removed ( 700 x 2 = 1400)
Final weight is 1,100 pounds
g + 200 - 1400 = 1100
Simplify:
g - 1200 = 1100
Add 1200 to both sides:
g = 2300 pounds
Y(3y-4)
The y can be factored out of both equations
Elimination:
3x - 9y = 3
6x - 3y = -24
3x - 9y = 3
18x - 9y = -72
(subtract)
-15x = 75
÷ -15
x = -5
(3 × -5) - 9y = 3
-15 - 9y = 3
+ 15
-9y = 18
÷ -9
y = -2
Substitution:
6x - 3y = -24
+ 3y
6x = -24 + 3y
÷ 6
x = 4 + 0.5y
3(4 + 0.5y) - 9y = 3
12 + 1.5y - 9y = 3
12 - 7.5y = 3
- 12
-7.5y = -9
÷ -7.5
y = 1.2
x = 4 + (0.5 × 1.2)
x = 4 + 0.6
x = 4.6
So this one didn't fail as much, but I got different numbers. If you have to give in values, I'd give in the values from the elimination because I don't trust myself when it comes to the substitution
