How do you evaluate expressions? - 1

Answer 1
Answer: 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.

Tom has offered to sell Julian his motorcycle for $1,200. Julian knows this is a very good deal, since the same motorcycle can be purchased at the dealership for $1,800. Since Julian doesn’t have $1,200 and Tom does not accept credit cards, they both think a cash advance might be a good idea. Julian’s credit card company can offer him a cash advance for the $1,200 he needs at an interest rate of 26%. He would then pay off the balance in 24 months. Should Julian use the cash advance to purchase the motorcycle? a. No. Julian would be paying too much in interest to warrant using a cash advance. b. Yes. Even with the interest, the total cost of the motorcycle would be less than at the dealership. c. Yes. The interest rate on the cash advance is low. Julian will not have to pay much interest on the cash advance. d. No. The high interest rate on the cash advance would make the purchase of the motorcycle almost twice than the price at the dealership.

WHAT IS THE VALUE OF ANGLE N?

Answers

Answer:

32 degrees

Step-by-step explanation:

An inscribed angle is an angle with its vertex on the circle, formed by two intersecting chords. Angle N perfectly fits this description. An inscribed angle is equal to 1/2 of its intercepted arc (the arc opposite the angle). The arc opposite angle N is equal to 64 degrees, so angle N is equal to 1/2 of that, or 32 degrees

PLEASE SOLVE THIS!!

Answers


-3X+4=16

Subtract 4 from each side.

-3x+4-4=16-4

-3x=12

Divide each side by -3.

x=-4

I hope this helps!

-3x+4=16
Subtract 4 from 16 
-3x=12
x= -4 because 3 times 4 =12 yet in order to make a negative number into a positive number, put two negative numbers together, and it's positive.

If the midpoint between (x, 3) and (9, 9) is (7, 6), find the value of x.

Answers

The midpoint formula states that the midpoint is equal to (x1 + x2/2, y1 + y2/2). However, in this instance, we only have to deal with the x-values because that is where our unknown variable x is. Using our formula for the x-values, we can set up the following equation:

(x + 9)/2 = 7

To solve this equation, we must first multiply both sides by 2 to get rid of the denominator on the left side of the equation.

x + 9 = 14

Next, we should subtract 9 from both sides of the equation to get the variable x alone on the left side.

x = 5

Therefore, your answer is x=5.

Hope this helps!
