Answer:
<em>He bought 6 hotdogs and 2 drinks</em>
Step-by-step explanation:
<u>System of Equations</u>
Kevin and his children went into a restaurant and bought $31.50 worth of hotdogs and drinks. Each hotdog costs $4.50 and each drink costs $2.25.
To solve the system of equations, we'll call the variables:
x = number of hotdogs
y = number of drinks
The first condition yields the equation:
4.50x + 2.25y = 31.50 [1]
It's also known he bought 3 times as many hotdogs as drinks, thus:
x = 3y [2}
Substituting [2] in [1]:
4.50(3y) + 2.25y = 31.50
Operating:
13.5y + 2.25y = 31.50
15.75y = 31.50
y = 31.50/15.75
y = 2
And
x = 3*2 = 6
He bought 6 hotdogs and 2 drinks
Equation of line passing through (2, -2) and parallel to 2x+3y = -8 is
<h3><u>
Solution:</u></h3>
Need to write equation of line parallel to 2x+3y=-8 and passes through the point (2, -2)
Generic slope intercept form of a line is given by y = mx + c
where "m" = slope of the line and "c" is the y - intercept
Let’s first find slope intercept form of 2x+3y=-8 to get slope of line
On comparing above slope intercept form of given equation with generic slope intercept form y = mx + c,
We know that slopes of parallel lines are always equal
So the slope of line passing through (2, -2) is also
Equation of line passing through and having slope of m is given by
Substituting the values in equation of line we get
Hence equation of line passing through (2 , -2) and parallel to 2x + 3y = -8 is given as
Seven days and a half
For you work 8 hours a day
It takes you 6 hours to per each
You wanna make 10
10 by 6 is 60 on 8 = 7.5
Best luck!

Answer:
x = 2
Step-by-step explanation:
Given
8(4 - x) = 7x + 2 ← distribute parenthesis on left side
32 - 8x = 7x + 2 ( subtract 7x from both sides )
32 - 15x = 2 ( subtract 32 from both sides )
- 15x = - 30 ( divide both sides by - 15 )
x = 2
