I don’t think it’s the second or third one I’m narrowing it down to the first or maybe fourth
I think the answer is the first one though
General formula for circles at the origin is x^2+y^2=R^2 where R is the radius.So R^2=4225. Solve for R.
Step-by-step explanation:
3x - 2x + 8 = 12; x=4
Now, Evaluate the value of x
3(4) - 2(4) + 8 = 12
12 - 8 + 8 = 12
12 + 0 = 12
12 = 12
Distribute 2 and remove parentheses :
1/2x+8=3x-6
Multiply both sides of equation by 2:
x+16=6x-12
Move terms:
x+16-6x=-12
x-6x=-12-16
Collect like terms:
-5x=-28
Divide both sides:
x=28/5
2.5 2 cup servings of flour are used. For every serving of flour, there are 2/3 cups of sugar. So, we need to use 2.5 servings of sugar, too. (2/3)*2.5= 5/3, or 1.6666.... cups of sugar.
