Answer:

See below

Step-by-step explanation:

16 + (18 + 10) = (x + 18) + 10x

16 + 28 = (x + 18) + 10x Add like terms in the parentheses

44 = (x + 10x) + 18 Use the community property to regroup like

terms

44 = 11x + 18 Simply

-18 = -18 Substract 18 from both side

26 = 11x Simply

26 = 11x Divide by 11

11 11

$2\frac{4}{11} = x$ Reduce

Incomplete question

Complete question;

A group of eight golfers paid $430 to play a round of golf . Of the golfers one was a member and 7 were not.

Another group of golfers consists of two members and one nonmember. They paid a total of $75. What is the cost for a member to play a round of golf, and what is the cost for a nonmember?

Answer: X = $82.695 for members

Y = $49.615 for non members

Step-by-step explanation:

Let's use X to denote members and Y for non-members.

Therefore, amount paid by one member to play + amount paid by 7 non-members to play = 430

X + 7Y = 430. . .1

Amount paid by 2 members to play + amount paid by one non-member to play = 215

2X + Y = 215. . .2

Solving both equations simultaneously

X+7Y = 430

2X +Y = 215

Therefore, from eqn 1. X = 430-7y

Substituting this into wan 2 gives

2(430-7Y) + Y = 215

860-14Y + Y = 215

860-215 =13Y

645 = 13y

Y = 49.615

Therefore substituting Y = 49.615 into any equation above

X + 7(49.615) = 430

X = 430-347.05

X = 82.695

Question 2 (5 points)

IrinaK [193]

Answer:

$x - y + 5 = 0$

Step-by-step explanation:

Given:

Line passes through (-2,3) and (2,7)

Required:

Find the equation of the line

The equation of the line passing through two points is given by

$\frac{y-y_{1} }{y_{2}- y_{1} } =\frac{x_{}- x_{1} }{x_{2} -x_{1} }$

So, $\frac{y-3}{7-3} =\frac{x-(-2))}{2-(-2)}$

$\frac{y-3}{4} =\frac{x+2}{2+2}$

$\frac{y-3}{4} =\frac{x+2}{4}$

Now, $y-3 = x+2$

On rearranging,

$x - y + 3 + 2 = 0x - y + 5 = 0$

Therefore, the equation of the line is $x - y + 5 = 0.$

stira [4]

Answer:

$x = 25$

Step-by-step explanation:

Interior angles of a triangle = 180°

$3x + 67 + 38 = 180 \\ 3x + 105 = 180 \\ 3x = 180 - 105 \\ 3x = 75 \\ \\ x = \frac{75}{3} \\ \\ x = 25$

I hope I helped you^_^
