Answer:

B) Line 2

using the formula:

\sf c^2 = a^2 + b^2 -2abcos(C)

\sf c^2 = 14^2 + 8^2 -2(14)(8)cos(80)

\sf c^2 = 196 + 64 -244 *0.173

\sf c^2 = 221.1

\sf \sqrt{c} = \sqrt{221.1}

\sf c = 14.87

Katyanochek1 [597]
It isn't A because there isn't a decimal in the hundredths.
It isn't B because it doesn't have a decimal coefficient on the left side: that means it could be C or D, to find out we should find what x is in C:
0.5x-5=0.15x+2
0.5x=0.15x+7
0.35x=7
Divide both sides by 7
0.05x=1
Now multiply both sides by 20:
x=20
That means it must be D, let's make sure:
0.6x-3=0.28x+5
0.6=0.28x+8
0.32x=8
Divide both sides by 8:
0.04x=1
Now multiply both sides by 25:
x=25
So the answer is D

Hope this helps :)

Cloud [144]

Answer:

15 ounces per box

Step-by-step explanation:

The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weight of the crackers in the boxes. What is the weight, in ounces, of one box?

Total weight of crackers in the boxes = 165 ounces

Total number of boxes = 11 boxes

What is the weight, in ounces, of one box?

Weight per box of crackers =

Total weight of crackers in the boxes / Total number of boxes

= 165 ounces / 11 boxes

= 15 ounces per box

The weight, in ounces, of one box is 15 ounces

4vir4ik [10]

Answer:

\large\boxed{y-5=-4(x-3)}\\\boxed{y-8=\dfrac{1}{2}(x+1)}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

m=-4,\ (3,\ 5)\\\\y-5=-4(x-3)

m=\dfrac{1}{2},\ (-1,\ 8)\\\\y-8=\dfrac{1}{2}(x-(-1))\\\\y-8=\dfrac{1}{2}(x+1)
