-3 on both sides
7x=14
Divided by 7 on both sides
x=14/7=2
The answer will be x=2

Mrs. Suarez sold pies for a fundraiser. she sold 3 5/6 pies the first day and 1 3/6 the second day. how many pies did she sell i
LuckyWell [14K]

Answer: 5 2/6

Step-by-step explanation: 3 5/6 + 1 3/6 = 5 2/6 because you need to add the pie wholes,(3 + 1) and then you have the fractions, 5/6 + 3/6. So since all you need to make another whole is 1/6 you take it away from 3/6 and give it to 5/6 so now you have another whole. 4 wholes plus 1 new whole is 5 wholes. Since you took 1/6 away from 3/6 you now have 2/6. So 5 wholes and 2/6 were sold.

3 5/6 + 1 3/6 =

3 + 1= = 4

5/6 + 1/6 = 1

3/6 - 1/6 = 2/6

4 + 1 = 5

5 + 2/6 = 5 2/6

Vitek1552 [10]

Answer: σ: 2.76

Step-by-step explanation:

Count, N: 5

Sum, Σx: 125

Mean, μ: 25

Variance, σ2:  7.6

Steps

look at attached pic for formula

σ^2 = \frac{Σ(xi - μ)^{2} }{N}

\frac{(21 - 25)2 + ... + (29 - 25)2}{5}

⇒ \frac{38}{5}

⇒ 7.6

σ =  \sqrt{7.6}

⇒   2.756809750418

⇒ or 2.76

I need help please helppppppppppppppppppppppp
Marrrta [24]

Given:

A figure of a circle and two secants on the circle from the outside of the circle.

To find:

The measure of angle KLM.

Solution:

According to the intersecting secant theorem, if two secant of a circle intersect each other outside the circle, then the angle formed on the intersection is half of the difference between the intercepted arcs.

Using intersecting secant theorem, we get

\angle KLM=\dfrac{1}{2}(Arc(JON)-Arc(KM))

(3x-4)=\dfrac{1}{2}(271-(x+6))

(3x-4)=\dfrac{1}{2}(271-x-6)

Multiply both sides by 2.

6x-8=265-x

Isolate the variable x.

6x+x=265+8

7x=273

Divide both sides by 7.

x=\dfrac{273}{7}

x=39

Now,

\angle KLM=(3x-4)^\circ

\angle KLM=(3(39)-4)^\circ

\angle KLM=(117-4)^\circ

\angle KLM=113^\circ

Therefore, the measure of angle KLM is 113 degrees.
