80.332161 in

Answers

Answer 1
Answer:

Answer:

75.398223

Step-by-step explanation:

Circumference Formula: 2πr or dπ ⇒ r=radius and d=diamater

1.) π≈3.14

2.) 24×3.14=75.36

d1) 20°

Complement: 90° - 20° = 80°

Supplement: 180° - 20° = 160°

d2) 77°

Complement: 90° - 77° = 13°

Supplement: 180° - 77° = 103°

d3) 101°

Complement: doesn't have a complement.

Supplement: 180° - 101° = 79°

d4) 90°

Complement: 90° - 90° = 0°

Supplement: 180° - 90° = 90°

d5) 96°

Complement: doesn't have a complement

Supplement: 180° - 96° = 84°

d6) x

Complement: 90° - x

Supplement: 180° - x

d7) y

Complement: 90° - y

Supplement: 180° - y

Solve by substitution
y=x+3
y=2x+5

Answers

y = x+3
y = 2x+5
x+3 = 2x+5
x+8 = 2x
x = 8

I think I did that right, anyway.
y=x+3
y=2x+5

1. Solve for the variable that is easiest to find. 
     In this case I will solve for x.
y=x+3
-3       -3
y-3=x

2. Now plug in (y-3) for x in the other equation.
   y=2(y-3)+5  ~use distributive property 
   y=2y-6+5     ~combine like terms
   y=2y-1
-2y=-2y
  -y=-1             ~multiply both sides by -1
   y=1
 
3. Since you have a value for y you can plug it in to solve for x.
     y=x+3
    1=x+3
    -3    -3
    -2=x

Answers: 
y=1
x=-2

Write the expression -3x 2 + 2y 2 + 5xy - 2y + 5x 2 - 3y 2 in simplest form. Then, answer the following questions using complete sentences.How many terms are in the simplified expression?
How many of the terms in the simplified expression are negative?

Answers

combine like terms
assuming those 2s are exponents

-3x^2+2y^2+5xy-2y+5x^2-3y^2
move all x's together all y's together and all xy's together

-3x^2+5x^2+2y^2-3y^2+5xy
combne like terms
2x^2-y^2+5xy

3 terms
1 term is negative

Which point on the axis satisfies the inequality y < x? (1 point)
(0,1)
(-1,0)
(1,0)
(0,0)

Answers

y < x means the value of y is less than the value of x the values in your coordinates are (x,y) so plug them in option C is correct 0 < 1
