The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x.

Hint: Triangles have 3 sides.

Answers

Answer 1
Equilateral triangle have the same side lengths. Perimeter = sum of all sides
(4x - 3) + (4x - 3) + (4x - 3) = 63
Remove parentheses
4x - 3 + 4x - 3 + 4x - 3 = 63
Combine like terms
12x - 9 = 63
12x = 72, x = 6

Solution: x = 6

4x + 10 = -26

Subtract 10 from both sides

4x = -36

Divide each side by 4

x = -9

To check it, substitute -9 for x in the original equation.

4(-9) + 10 = -26

-36 + 10 = -26

-26 = -26

Answer:

X=-9

Step-by-step explanation:

A bank offers a savings account with a yearly simple interest rate of 2%. Suppose you deposit $550 into a savings account. How much simple interest will you earn in 4 years and six months?

Answers

Answer:

49.5(interest)

599.5 (total amount)

Step-by-step explanation:

A=P(1+rt)

A=550(1+.02*4.5)

A=550(1+.09)

A=550(1.09)

A=599.5 (total amount)

599.5-550=49.5(interest)

550 x 0.02 = 11

11 x 4.5 = 49.5

Answer:

Part A: The equations are:

y = -1/2x + 2, and

y = 3x - 5

Part B: The solution is (2,1)

Step-by-step explanation:

Part A: There are two equations we need to find, each line is the graph of a function.Graphs are written in y = mx + b, m is the slope, which is the change in y divided by the change in x, and b is the y - intercept. To find the function of the first graph, the one going slightly down, the slope is: y goes down by one, and x increases by 2, so change in y/ change in x is -1/2. The y - intercept is where the graph goes through the point where x is 0, on this graph, the point is (0,2), the y - intercept is 2, so y = mx + b is y = -1/2x + 2

For the other equation, slope is when y increases by 3, x increases by 1, so 3/1, or 3. The y - intercept is -5, so y = 3x + (-5), or y = 3x - 5

Part B: The solution to this equation is the point where both of the functions meet, here, this point is (2,1), y is 2 and x is 1.

The drama club sold 415 Manatee tickets to the school's play for $7.95 each 18 of the tickets were refunded estimate the tickets is your estimate and overestimate or an underestimate. PLZ HELP ASAP!!!!!!

Answers

since you always round up when you estimate in the middle lets say theres 420 tickets. Each is 7.95, but we'll round it to 8.00. 420x8.=3,360. After that part we need to find about how much tickets were refunded. So we round 18 to 20 and each ticket is still 8$. 20x8=160. Finally in all, we do 3,360-160=3200. Its an overestimate because we rounded up. Im not sure what else youre asking but thats the basic answer.
