Pete Smith bought two new car tires from Firestone for $89.95 per tire. Firestone charged Pete $3.25 per tire for mounting, $2.6
den301095 [7]
First youll need to add all the numbers together to get the cost of one tire
89.95 + 3.25 + 2.60 + 3.80 = $99.60 
now that we know how much one tire costs, we can multiply the price of one tire by two to found out his final bill
99.60 x 2 = $199.20
Pete's final bill is $199.20 
let me know if you have any other questions

Solve the following system of equations: x + 3y = 10 and 2x + 2y = 12
Thepotemich [5.8K]

Answer:

x=4 and y=2

Step-by-step explanation: Step 1: Solve x+3y=10 for x:

x+3y=10

x+3y+−3y=10+−3y(Add -3y to both sides)

x=−3y+10

Step 2: Substitute−3y+10for x in2x+2y=12:

2x+2y=12

2(−3y+10)+2y=12

−4y+20=12(Simplify both sides of the equation)

−4y+20+−20=12+−20(Add -20 to both sides)

−4y=−8

−4y

−4

=

−8

−4

(Divide both sides by -4)

y=2

Step 3: Substitute 2 for y in x=−3y+10:

x=−3y+10

x=(−3)(2)+10

x=4(Simplify both sides of the equation)

So your answer would be x=4 and y=2

Hope this helps

<h3>Trigonometric ratio</h3>

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let b represent the base of the triangle and h the height, hence:

sin(60) = h / 18

h = 15.6 feet

sin(30) = b / 18

b = 9 feet

The area of triangle = (1/2) * b * h = 0.5 * 9 * 15.6 = 70.1 ft²

70.1 ft² of fabric is needed by Lacy to make the sail boat.
