Answer:

Option b is right.

Step-by-step explanation:

Given that 8 more than twice a number is fifty

We have to create an algebraic expression for this.

SInce we do not know the number let us assume the number to be N.

Twice the number = 2 times N

= 2N

Now 8 more means we have to add 8 to the value

i.e. 2N+8

This equals 50 is given

Hence 2N+8 =50

Option b is correct.

grandma gigi gave leyla a rare purple stone for her sweet 16 birthday. at that time,the stone was worth$245. it has been increas

sergij07 [2.7K]

This is a compound interest problem, therefore s(t) should be in the form:
$s(t) = a(r)^{t}$

where:
t = time in years
s(t) = the value of your item after t years
a = the initial value of your item
r = rate

Therefore, we already know that a = 245$.

Now, we can calculate r:
$r^{t}=\frac{s}{a}$
$r = \sqrt[t]{ \frac{s}{a} }$
$r = \sqrt[5]{ \frac{560.50}{245} }$
= 1.18

Therefore, the correct answers are a = 245 and r = 1.18

An angle measures 73.6° less than the measure of its supplementary angle. What is the measure of each angle?

Vladimir79 [104]

Answer:

Smaller angle = 53.2

Larger angle = 126.8

Step-by-step explanation:

Lets say x is the measure of the supplement. Since we know they're supplementary, we know their angle measure sum will equal 180. We can set up our equation like this $x + (x-73.6) = 180$ . Note: (x - 73.6) is the measure of the smaller angle. By solving, we get 126.8 degrees for the measure of the supplement. If we plug in the value of x into (x-73.6), we get 53.2 degrees as the angle measure of the smaller angle.
