Answer: There are 4 more wrenches in the toolbox then the screwdrivers.
Step-by-step explanation: Add the 6 wrenches Sid put in the toolbox with the 8 wrenches Bella added to get 14 wrenches in total. Then, subtract the 10 screwdrivers from the 14 wrenches to get 4 wrenches.
Direct proportion equations have the following form:
Where "k" is the Constant of proportionality.
In this case you know that "y" is directly proportional to "x" and when:
Having these values, you can substitute them into the equation and solve for "k":
So, substituting the value of "k" into the first equation shown above, you get that the equation that models the given relationship is:
Now, to find the value of "x", when the value of "y" is -24, you must substitute this value into the equation that models the relationship and then solve for "x". Then, you get:
Therefore, the answers are:
All the angles make a full circle which needs to equal 360 degrees.
Add all the angles together to equal 360:
X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360
Combine like terms:
9x -30 = 360
Add 30 to both sides:
9x = 390
Divide both sides by 9:
X = 390/9
X = 43.3333. ( 43 and 1/3)
Answer:
b. 5x + 4y = 80
Step-by-step explanation:
Let us assume the remaining balance left be Y
and, the number of songs purchased be X
Given that
Wins a gift card of $20
And, the songs purchased is 16
Now if we take the fraction
= 20 ÷ 16
= 5 ÷ 4
So if we reverse this fraction
So it could be 5x and 4y
And, the amount that would come is
= $20 × 16 ÷ 4
= 80
So, the equation is 5x + 4y = 80
Hence, the correct option is b.
