4 oz/2.5 gal garden spray = <em />6/<em>x
</em>4<em>x = 15
x </em>= 15/4 or 3.75
Answer:
Step-by-step explanation:
(5⅔)/4 = (17/3)/4 = 17/12
Let, cost of 1 hot dog and 1 drink is x and y respectively.
Carl bought 4 hot dogs and 6 drinks and paid $23.80.
4x + 6y = 23.80 ....1)
Susan purchased 4 hot dogs and 2 drinks and was charged $15.40.
4x + 2y = 15.40 ....2)
Subtracting equation 2 by 1, we get :
(4x + 6y) - (4x + 2y) = 23.80 - 15.40
4y = 8.4
y = $2.1
4x + 6×2.1 = 23.80
4x = 23.80 - 12.2
4x = 11.6
x = 2.9
Therefore, the cost of 1 hot dog and what is the cost of 1 drink is $2.9 and $2.1 respectively.
Hence, this is the required solution.
Answer:
5.5
Step-by-step explanation:
y = 0.5x + 5
Use the slope-intercept form to find the slope and y-intercept.
<em>Slope: 0.5
</em>
<em>y-intercept: 5
</em>
Any line can be graphed using two points. Select two <em>x</em> values, and plug them into the equation to find the corresponding values.
To find the y intercept using the equation of the line, plug in 0 for the <em>x</em> variable and solve for y.
<em>y = 0.5(0) + 5
</em>
<em>y = 5</em>
To graph the y intercept using the equation of the line, plug in 1 for the x variable and solve for y.
<em>y = 0.5(1) + 5
</em>
<em>y = 5.5
</em>
Which means when x is 0, y intercept at 5 and when x is 1 y intercept at 5.5. Graph the line using the slope and the y-intercept, or the points.
This tells us, in practical terms, that, for every one unit that the x-variable increases (that is, moves over to the right), the y-variable increases (that is, goes up) by 50% of a unit.
