The interior of a triangle = 180°
So 180° - 85° -50° = 45°

c. 45 degrees

Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if

BigorU [14]

Answer:

$x = 5$

$R = C = 225$

Step-by-step explanation:

Given

$C = 15x + 150$

$R = 45x$

Required

The break even point

To do this, we make use of:

$R =C$

$45x=15x + 150$

Collect Like Terms

$45x-15x = 150$

$30x = 150$

$x = 5$

Substitute 5 for x in $R = 45x$

$R = 45 * 5$

$R = 225$

Hence, the break even point is:

$x = 5$

$R = C = 225$

The length of a rectangle is 3 inches more than its width. The perimeter of the rectangle is 34 inches. The length of the rectan

astra-53 [7]

Answer: Width= 7 in.

Length= 10 in.

Step-by-step explanation:

$l=w+3$

The perimeter of the rectangle is 34 inches.

$2(w+l)=34$

substitute

$2(w+w+3)=34$

$2(2w+3)=34$

distributive property $a(b+c)=ab+ac$

$2\cdot 2w+2\cdot 3=34$

$4w+6=34$

$4w+6-6=34-6$

$4w=28$

divide 4 on both sides

$w=7$

Width is 7 inches

substitute w=7 in equation $l=w+3$

$l=7+3$

$l=10$

Length is 10 inches

A triangle has a perimeter of 72 units, and two of its sides measure x units and 3x units, respectively. Which inequality repres

blagie [28]

Answer:

$x$

Step-by-step explanation:

Given: Perimeter of triangle= 72 units

Measure of one of the side= x units

Measure of second side = 3x units

We know the perimeter of triangle is equal to sum of all sides.

Now, finding the possible value of x

forming an inequality to determine the value of x

Remember triangle has three sides, however, measure of only two sides are given.

⇒ $x+3x < 72\ units$

⇒ $4x$

Dividing both side by 4

⇒ $x < 18$

∴ The inequality to represents all possible values of x is $x < 18$
