Answer:

A = 58.9 degrees

Step-by-step explanation:

straight line angles add up to 180 degrees

121.1 + A = 180

A = 180 - 121.1

Line BC has an equation of a line Y equals 2X +3 and F has an equation of a line Y equals -1/2 x+4 these two equations represent
Masja [62]

Answer:

Lines BC and F represent perpendicular lines

Step-by-step explanation:

we have

<em>Line BC</em>

y=2x+3

the slope of the line BC is m=2

<em>Line F</em>

y=-(1/2)x+4

the slope of the line F is m=-1/2

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

so

m1*m2=-1

we have

m1=2 -----> slope line BC

m2=-1/2 -----> slope line F

Find the product of their slopes

(2)(-1/2)=-1

therefore

Lines BC and F represent perpendicular lines

Mark and Don are planning to sell each other their marble collections at a garage sale. If Don has 1 more than 3 times the numbe
Volgvan

Answer: Mark has 28 marbles while Don has 85 marbles.

Step-by-step explanation:

Let x represent the number of marbles that Mark has.

Let y represent the number of marbles that Don has.

If Don has 1 more than 3 times the number of marbles Mark has, it means that

y = 3x + 1

The total number of marbles is 113. It means that

x + y = 113- - - - - - - - - - - - 1

Substituting y = 3x + 1 into equation 1, it becomes

x + 3x + 1 = 113

4x + 1 = 113

4x = 113 - 1 = 112

x = 112/4

x = 28

y = 3x + 1 = 3 × 28 + 1

y = 85
