Centralangle/360 times area of circle=sector area
120/360 times pi8²=
(1/3)(64pi)=64pi/3 square inches
9.4 because the number after the firs decimal point is higher than 5
You should subtract the powers when they are divided and add them when they are multiplied this rule is so important for now you just have to subtract them and you will get the answer
Hope it helps :)
You have the value for y, so you substitute that equation for y, times three because there are three yS.
So you have: 2x + 3y = 10
2x + 3 x 2x + 4 or 2x + 3(3x + 4)
so the answer would be B, 2x + 3(3x + 4)
Answer:
y = -5
Step-by-step explanation:
Isolate y:
-3x + 9y = -57
9y = -57 + 3x
y = (-57/9) + (3/9)x
Substitute for x:
y = (-57/9) + (3/9)(4)
y = (-57/9) + (12/9)
y = (-45/9)
y = -5
