A triangle has angles that measure 43°, 7 minus 3x.° and 6x.°. Which equation can be used to find the value of x?

The value of is 15.222. We need to use the following equation:

Step-by-step explanation:

From Euclidean Geometry, we know that the sum of measures of internal angles in a triangle equals 180º. Then, we can find the value of by this formula:

(1)

The value of is 15.222.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
