Aweekend at the beach bag hotel in florida includes two nights and four meals for 195. a week includes seven nights and ten meals for $650. how much does a night stay and meal cost

A night stay and meal cost= $40.18

Step-by-step explanation:

Simultaneous equations

2n +4m=195 x 10

7n+10m=650 x 4

28n+40n= 2600

20n+40n=1950

Subtract

8n=650

1 night= 81.25

Substitute

81.25 x 2 +4m=195

162.5+4m=195

4m= 32.5

1 meal= 8.13

1 night and meal= $40.18

yes

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
