Answer:
x = 40
Step-by-step explanation:
Using similarity theorem, we have the following:
Solve for x
Cross multiply
Subtract 24x from each side
Divide both sides by -15
40 = x
x = 40
Answer:
The graph is attached.
Step-by-step explanation:
The graph of the line with the slope and the y-intercept , has the form
In our case the rate of change is ; therefore we have the equation
The graph of which is attached.
<em>P.S: we have set </em><em> by default, because we are not given any information for it. </em>
For this case we propose a system of equations:
x: Variable representing the amount of oranges
y: Variable that represents the amount of grapefruit
We have to meet a citrus gift package:
From the second equation we have to:
We replace in the first:
Thus, the package has 3 grapefruits.
On the other hand:
Thus, the package has 9 oranges.
Answer:
9 oranges
Plug in (1,8) to y ≤ 2x+2 and you get 8 ≤ 2+2 which is not true
90% of 130 is 117 because 10% is 13 and 13x9 is 117 so that is part a. 130-117 is 13 so that is part b. And part c is correct because 100%-90%=10%. I hope this is helpful.
