We need to multiply Y by 3 since it says "3 times the number".

3Y; next we need to add 4 since it says 4 more.

3y+4; the reason I knew to put it in this order is because it said 4 more than 3 times, which means you add 4 after you multiply.

The expression is 3Y+4

What is 5 1/6 minus 1 1/3

zaharov [31]

We must find the common denominator.

LCM(6, 3) = 6

$5\dfrac{1}{6}-1\dfrac{1}{3}=5\dfrac{1}{6}-1\dfrac{1\cdot2}{3\cdot2}=5\dfrac{1}{6}-1\dfrac{2}{6}=(5-1)+\left(\dfrac{1}{6}-\dfrac{2}{6}\right)=4-\dfrac{1}{6}=3\dfrac{5}{6}$

or other method of calculating the difference

$5\dfrac{1}{6}-1\dfrac{2}{6}=4\dfrac{6+1}{6}-1\dfrac{2}{6}=4\dfrac{7}{6}-1\dfrac{2}{6}=(4-1)+\left(\dfrac{7}{6}-\dfrac{2}{6}\right)=3\dfrac{5}{6}$

What is the radius, in centimeters, of a circle that has a circumference of 161 centimeters?

elena-14-01-66 [18.8K]

Answer:

25.63694268 = r

Step-by-step explanation:

The circumference is

C = 2*pi*r

161 = 2*(3.14) *r

161 = 6.28 r

Divide each side by 6.28

161/6.28 = r

25.63694268 = r

Suppose the graph of y= x^2 translated left 2 units, and up 8 units

Elis [28]

Start with y = x2

Shift 2 units left to get y = (x+2)2

Vertically stretch to get y = 6(x+2)2

Reflect across x-axis to get y = -6(x+2)2

Shift 7 units down to get y = -6(x+2)2 - 7

hope this helps!
