Joshua sells a pack of pens for $3.15 which is 5 percent more that he pays for them. Which equation will help find x, the amount he pays for a pack of pens? how many solutions will this equation have?A) x+0.05x=3.15 infinitely many solutions.
B) x+0.5x=3.15 one solution
C) x+0.05=3.15 one solution
D) 0.05x=3.15 no solution

Answers

Answer 1
Answer:

Answer:

x+0.05x=3.15

Step-by-step explanation:x= the amount he pays for a pack of pen

x+0.05x=3.15   , which has one solution.

1.05x=3.15

x=3.15/1.05=3

he pays for a pack of pens 3

Answer: x+0.05x=3.15   , which has one solution.

The area of a sector of a circle with a radius of 4 centimeters is 2.512 square centimeters. The estimated value of ╥ is 3.14. The measure of the angle defining the sector is

Answers

The equation for the area of a sector of a circle is expressed as the product of pi, square of the radius and the ratio of the angle of the sector and 360 degrees.

Area = πr^2 (α / 360°)

We obtain the angle by manipulating the equation.

α = (Area x 360°) / πr^2 
α = (2.512 cm^2 x 360°) / (π x 4^2)
α =35.98°

The plaid flannel shirt that you have
wanted for months is now on sale at the mall for $35. Sales tax at the
mall is 7%. Before you leave to buy the shirt, you see an ad for the
same shirt for $30 with a sales tax of 9.5% at a shop 20 miles away.
Decide which shirt is the better buy and tell why. Can you think of one
reason that would make the more expensive shirt a better buy?

Answers

The shirt that costs 35.00 is the better buy because even though the shirt is more expensive than the other, it also has less tax. Also the shirt is local which saves you money on gas and wear and tear on your vehicle. In the end the 35.00 shirt is your smartest bet!

How do you evaluate expressions?

Answers

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
