Solve the following system:
{x + 3 y = 8
{4 x - y = 6
Solve for x:
x/3 + y = 1
Subtract y from both sides:
x/3 = 1 - y
Multiply both sides by 3:
Answer:  x = 3 - 3 y

Three friends go bowling at "Strike Out" on Friday night. The cost per person per game is $5.30. The cost to rent shoes is $2.50
kvv77 [185]

Answer:

They played 3 games of bowling.

Step-by-step explanation:

Assuming each person only rents one pair of shoes, that would come out to $7.50.

Subtract this amount from the total ($55.20) and you get $47.70 leftover.

Divide the leftover amount by the price of games per person ($5.30) and you'll get nine, divide that by the number of people playing, since it's per person, and you can determine they played three games.

Use Heron's Area Formula to find the area of the triangle. (Round your answer to two decimal places.) A = 79°, b = 77, c = 43
BlackZzzverrR [31]

Answer:

1549.5

Step-by-step explanation:

Hello There!

Heron's area formula is

A=\frac{(a)(b)sin(c)}{2}

all we have to do is plug in the values

so

A=\frac{77*41sin79}{2} \\77*41=3157\\3157sin79=3098.997018\\\frac{3098.997018}{2} =1549.498509

so the area of the triangle is 1549.498509

our final step is to round to the nearest hundredth

the answer would be 1549.5
