The circumference is (2 pi) (radius) . The ratio of radius to circumference is (1)/(2 pi).
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Order of operations multiplication then subtraction so 5*6=30
34-30=4
<h3><u>The value of the larger number, x, is 57.</u></h3><h3><u>The value of the smaller number, y, is equal to 42.</u></h3>
x - y = 15
2x + 8 = 3y - 4
We can quickly get a temporary value for x by altering the original equation.
x - y = 15
<em><u>Add y to both sides.</u></em>
x = 15 + y
Now that we have a value of x, we can find the exact value of y.
2(15 + y) + 8 = 3y - 4
<em><u>Distributive property.</u></em>
30 + 2y + 8 = 3y - 4
<em><u>Combine like terms.</u></em>
38 + 2y = 3y - 4
<em><u>Subtract 2y from both sides.</u></em>
38 = y - 4
<em><u>Add 4 to both sides.</u></em>
y = 42
Now that we know the exact value of y, we can plug it back into the original equation.
x - 42 = 15
<em><u>Add 42 to both sides.</u></em>
x = 57
The six dollars for eight ounces is the cheaper one.
you have to find the common denominator between 5 and 8, the simplest I thought of was forty so to get the eight to forty, you multiply by five and six times five equals thirty and you do the same for the other one except it's times eight for this one so it'll equal thirty two, so there isn't much difference (two) but the first bottle has the lower unit rate
