weekdays and weekend days did Jamal park?

HELP PLEASE A Parking Lot Charges $7 Per Day To Park On Weekdays And $12 Per Day On Weekends.Jamal Parked

Answers

Answer 1

Answer:

4 weekdays and 2 weekends.

Step-by-step explanation:

6 days.

x = weekdays

y = weekends

7x = amount with weekdays

12y = amount with weekends

7x + 12y = 52, total

x + y = 6, amount of days

solve double variable equation

x = 6 - y, plug in to 1st equation

7(6 - y) + 12y = 52

42 - 7y + 12y = 52

5y = 10

y = 2 weekends

2 + x = 6

x = 4 weekdays

The area of a circle is 9π ft What is the circumference, in feet? Express your answer in terms of \piπ. (pi)

Answers

Answer:

6×pi ft

Step-by-step explanation:

the area of a circle is

pi × r²

with r being the radius of the circle.

so,

9×pi = r² × pi

9 = r²

r = 3 ft

the circumference of a circle is

2×pi× r

what is intercept: intercept simply means a point on the y axis through which a slope passes and also in the equation you were given y = mx + c I mean y = 2x -2 the c is the intercept meaning -2 .

so wherever that straight line meets with with y axis the number at that very point is your intercept.

the y intercept for the first one is -2

A $425.92
C
$124.08
B $132.00
D
$58.08

Answers

Answer:

A) $425.92

Step-by-step explanation:

The new price percentage with relation to the previous can be determined by dividing [tex]p = \frac{484}{550}[/tex]. Once we calculate p, we can multiply it by 484, which is equivalent to applying the same discount, thus [tex]\frac{484}{550}484=425.92[/tex]

A solution to -x + 10 = 2x + 4 is 8

Answers

Answer:

False.

Step-by-step explanation:

What is the question if you have the solution already?

I guess its a true/false question. In that case it's false because:

-x + 10 = 2x + 4

-x -2x + 10 = 4

-x - 2x = 4 - 10

-3x = -6

x = - 6 / -3

x = 2

Answer:

False.

This equation has only one solution, and it is x = 2.

Step-by-step explanation:

-x + 10 = 2x + 4

Subtract 2x from both sides.

-3x + 10 = 4

Subtract 10 from both sides.

-3x = -6

Divide both sides by -3.

x = 2

False.

x =

Answers

Answer:

x = 39

Step-by-step explanation:

all triangles have angle measures that add up to 180°.

This means that to find what x is, you add 102 and 39, and then subtract that from 180, so

180-(102+39) = x

180-141=x

39=x

Answer:

x° = 39°

Step-by-step explanation:

According to the angle sum property of triangles, the 3 angles in a triangle will sum up to 180°.

102° + 39° + x° = 180°

141° + x° = 180°

x° = 180° - 141°

x° = 39°
