Help please i am stuck

Mathematics
1 answer:
BaLLatris [955]3 years ago
6 0

Answer:

x = 25

Angle B = 65 degrees

Angle C = 50 degrees

Step-by-step explanation:

All triangles will add up to 180 degrees.

65 + 3x - 10 + 2x = 180

Combine like terms

55 + 5x = 180

Subtract both sides by 55

5x = 125

Divide both sides by 5

x = 25

Plug in the value for x in angle B:

3(25) - 10

75 - 10

65

Do the same for angle C:

2(25)

50

Check your work:

65 + 65 + 50 = 180

180 = 180

Correct

A teacher buys 100 pencils to keep in her classroom at the beginning of the school year. She allows the students to borrow penci
pashok25 [27]

Answer:

Step-by-step explanation:

The number of pencils at the beginning of the school year is 100. Since the pencils which she allowed the students to borrow is not usually returned. The rate at which she loses the pencils per month would constant. So the slope of the graph if number of pencils is plotted on the y axis and the months on the x axis,

The slope, m would be - 8 pencils per month because it is reducing

The equation for slope intercept form is expressed as

y = mx + c

Where

c = intercept

To determine c, we would substitute y = 100, x = 0 and m = 8 into the slope intercept equation. Ut becomes

100 = - 8×0 + c

c = 100

The equation becomes

y = - 8x + 100

A 1500 kg car speeds up from zero to 3.0 ms. it has kinetic energy of 6750 J at top spreed. True or False?
Andrew [12]

Answer:

True

KE = 1/2 mv^2

m = 1500 kg

v = 3 m/s

KE = 1/2 (1500 kg)(3 m/s)^2

KE = (750 kg)(9 m^2/s^2)

KE = 6,750 J

Find the equation of the line specified.<br> The slope is 7, and it passes through ( 8, 6).
STALIN [3.7K]

Answer:

The answer is A

Step-by-step explanation:

Given that the equation of line is y = mx + c and the slope is 7 :

y = 7x + c

By substituting the coordinate(8,6) into the equation, in order to find the value of c:

6 = 7(8) + c

6 = 56 + c

c = 6 - 56

= -50

y = 7x - 50
