14 POINTS ASAP WHAT IS THE MEASURE OF ANGLE A
sashaice [31]
Wow...we have lots of numbers to go through.  we know that a 6 sided figure is a hexagon and the interior angles add up to be 720°. so.....

∠A + ∠B + ∠ C + ∠D + ∠E + ∠F = 720°
(x - 60) + (x - 40) + 130 + 120 + 110 + (x - 20) = 720
3x + 240 = 720      (combined all like terms)
3x = 480                (subtracted 240 from both sides)
x = 160                  (divided both sides by 3)

put the value of x into ∠A  (x - 60) = 160 - 60 = 100

∠A = 100°

Ninety tickets were sold by our school for the band fest. a tickets were sold for $3.00 each and b tickets were sold for $4.00 e
Lesechka [4]

Answer: 60= $3.00 and 30= $4.00

x=# of $3 tickets

90-x=# of $4 tickets

$3x+$4(90-x)=$300

3x+360-4x=300

-x+360=300

-x=-360+300

-x=-60

x=60 $3 tickets

90-60=30 $4 tickets

HURRY !!! Farmer McHenry is going to sell his tomatoes at the farmer's market. It costs Farmer McHenry $2.50 in gas, $1 for the
Korolek [52]

Answer:

Step-by-step explanation:

The total cost that farmer McHenry assumes to sell his tomatoes at the farmer´s market includes: the gas, the stand and the price tags. The expression is the following:

Total cost = $2,50 + $1 + $0.50

Total cost = $4

Farmer McHenry's revenue depends on the number of tomatoes he sells:

Revenue (t)= Price* t

Revenue (t)= $0.50(t)

To know how many tomatoes, he must sell so that the cost equals his revenue, you must equal both expressions and then find t:

$4=$0.50 (t)

t= $4/$0.50

t= 8  

He must sell 8 tomatoes.

What is the y - intercept of y-8 = 2x *
Zielflug [23.3K]

Answer:

(0,8)

Step-by-step explanation:

First, we must arrange this equation into slope-intercept form, or  y=mx+b form.

Equation: y-8=2x

Add 8 to both sides: y=2x+8

Now that the equation is in slope-intercept form, it is easy to find the y-intercept, as it  is just the b-value.

In this case, the b-value is 8, so the y-intercept is (0,8).

Let me know if  this helps!
