If m∠ABC = 72°, what is m∠DAB?
A) 72°
B) 108°
C) 144°
D) 216°
If m∠ABC = 72°, what is m∠DAB? A) 72° B) - 1

Answers

Answer 1
Answer: m∠DAB + m∠ABC = 180°

m∠DAB + 72° = 180°

Subtract 72° on both sides.

m∠DAB = 180° - 72°

m∠DAB = 108°


Your final answer is B. 108°
Answer 2
Answer: m<DAB + 72 = 180

m<DAB = 108

The answer is B) 108

Jon has to pay $7.50 admission for the skating rink and $1.50 per hour to rent rollerblades. Write an equation for the cost (y) based on the number of hours(x).

Answers

Answer:

y = 7.50 + 1.50x

Step-by-step explanation:

The admission costs $7.50 and after x hours Jon has to pay $1.50*x. Then the cost y in dollars is

y = 7.50 + 1.50x where x is the number of hours.

Solve for x. Show all steps:1/5x+1/4x=1/2x+2

Simplify.

S-rs=a-ar5 how do i solve for s

Answers

Answer:

The value of s in the given equation is (a(1-r^5))/(1-r)

Therefore s=(a(1-r^5))/(1-r)

Step-by-step explanation:

Given equation is s-rs=a-ar^5

To find the value of s :

s-rs=a-ar^5

Taking common term "s" outside in LHS and common term "a" outside in RHS

s(1-r)=a(1-r^5)

Dividing by (1-r) on both sides we get

(s(1-r))/(1-r)=(a(1-r^5))/(1-r)

s=(a(1-r^5))/(1-r)

Therefore the value of s in the given equation is (a(1-r^5))/(1-r)

Therefore s=(a(1-r^5))/(1-r)

A student claims that 3x + 2y = 5xy. Use a visual representation to show whether this is true or false

Answers

Answer:

It is true, except when x = 2/5, since it is an asymptote.

Step-by-step explanation:

3x=5xy-2y

3x=y(5x-2)

3x/5x-2=y

5x-2=0 -------> 5x=2 --------> x=2/5

What expression can be used for estimating 868 divided by 28

Answers

868 is about 870, and 28 is about 30, so your expression would be 870 divided by 30 which would be 29 and the actual answer is 31, so your estimate would be close to your actual answer.
You could do 870/30=29.
Or you could do 868/28=31 and then round it but it looks like it doesn't need rounding.
