55, and the reason why bc the hole circle is 360 and so grab 360 - 170-80 equals to 110 right and we have to angles left so we divide. 110/2 equals 55
Change it to make y= on one side
3x + 4y = 1
4y = -3x + 1
y = -3/4x + 1/4
The slope is the fraction before x
The slope is -3/4
Answer:
{-11, -1}
Step-by-step explanation:
x^2 +12x = -11
Take the coefficient of x
12
Divide by 2
12/2 =6
Then square it
6^2 = 36
Add this to both sides
x^2 +12x+36 = -11+36
(x+6)^2 = 25
Take the square root of each side
sqrt((x+6)^2) = ± sqrt(25)
x+6 = ± 5
Separate into two equations
x+6 = 5 x+6=-5
Subtract 6 from each side
x+5-6 = 5-6 x+6-6 = -5-6
x=-1 x=-11
N= the number
n = 9 + 2(-n)
combine like terms:
-9= -3n
divide both sides by -3
n=3
Answer:
4 yds
Step-by-step explanation:
So... 16 yards is 48 feet (because one yard is 3 feet so I just multiplied by 3)
and she cuts 9 pcs of ribbon each 4 feet
so it's 9 x 4 = 36
48 - 36 = 12
And 12 feet equals 4 yards
So, Joy has 4 yards of remaining ribbon
